Technical Information

■Calculation of Life

When the linear systems are in motion with loads, rolling surfaces and races are subject to repeated stress and will show stress-induced scaly damages called "flaking". The total run distance of a linear system until this flaking first appears is the life of a linear system.

Rated life can be calculated using the formula below from the basic dynamic load rating and the actual load applied to the linear bushings.

L = ( f_H· f_T· f_Cf_w· CP )³· 50

L: Rated Life (km)
C: Basic Dynamic Load Rating (N)
P: Applied Load (N)
f_w: Load Factor (Refer to Table-4)
f_H : Hardness Factor (Refer to Fig.-1)
f_T : Temperature Factor (Refer to Fig.-2)
f_C : Contact Factor (Refer to Table-3)

Hardness Factor (f_H)

Temperature Factor (f_T)

When using linear systems, ample hardness of the shafts in contact with balls is needed as well.
If the ample hardness of the shafts are not obtained, the allowable loads are reduced and the life will be shortened.

When linear systems are exposed to temperature higher than 100°C, hardness will be reduced, and allowable loads and life will be reduced.

Fig. 1. Hardness Factor

Fig. 2. Temperature Factor

Contact Factor (f_c)

Load Factor (f_w)

Generally, more than 2 linear systems are used for 1 shaft. In this case, the load applied to each linear system will vary depending on machining accuracies and will not be equally distributed. As the result, allowable load per linear system will vary depending on the number of linear systems used on one shaft.

To calculate the load applied to the linear systems, in addition to object weight, it requires inertia force attributed to motion velocity or moment loads. Furthermore, it is necessary to accurately determine the temporal change of each. However, in reciprocating motion applications, it is difficult to obtain accurate calculations due to the effects of vibrations and shocks, in addition to those of repeated starting and stopping motions. Therefore, use the Table below in order to simplify the Life Calculations.

Table-3. Contact Factor

Table-4. Load Factor

Number of bushings on one shaft	Contact Factor f_c
1	1.00
2	0.81
3	0.72
4	0.66
5	0.61

Conditions of Use	f_w
No external shocks or vibrations when running in low speed: 15 m/min. or less	1.0 to 1.5
No excessive external shocks or vibrations when running in medium speed: 60 m/min. or less	1.5 to 2.0
External shocks and vibrations given when running in high speed: 60 m/min. or more	2.0 to 3.5

Life in hours can be obtained by calculating travel distance per hour.
If the stroke length and number of strokes are constant, life in hours can be calculated using the following formula.

L_h = L· 10³2· ℓs· n₁· 60

L_h: Life Hours (hr), Ls: Stroke Length (m), L: Rated Life (km)
n₁: Reciprocating Cycles per Minute (cpm)

Description/Basics

Linear ball bushings convert the rolling motion of steel balls (4) into infinite linear motion. They can implement highly precise and low-friction linear motion and can be used in almost all industries, e.g., in systems for semiconductor parts, electronic components and in food packaging.

Ball recirculating bushings are used in conjunction with linear shafts. The linear movement mechanism uses steel balls (4) for unlimited linear movement.

Linear bearing units allow linear shafts to travel indefinitely through steel balls that are constantly circulating within the running grooves directed by the outer cylinder and ball cage (3).

Compared to plain bearings, ball bushings perform linear movements with lower friction and high accuracy. They are used in many applications, such as conveyors and semiconductor manufacturing facilities.

Areas of Application

Linear ball bushings have a linear working direction and can be used for horizontal or vertical linear movements. Therefore, MISUMI linear ball bushings can be used in almost all industries. Since linear ball bushings are intended only for axial movement, rotational use would lead to premature fatigue or destruction of the ball bushings. For rotary movements, we therefore recommend ball cage guides, which enable not only infinite linear movements (stroke-limited) in addition to infinite rotary movements.

Common applications are lifting mechanisms or guides for cylinders. The ball bushings are also a good variant for additional guide. In addition, these linear ball bushings are often found in 3D printers, metering systems, measuring devices, positioning and alignment devices, bending devices and sorting systems.

For systems with increased particle development (e.g., dust and other abrasive particles), the linear systems should be protected with covers or bellows. The ingress of particles leads to a clumping of the lubricating grease or to significantly increased abrasion. By clumping the grease, the balls block in the ball circulation, which results in unscheduled maintenance.

Materials

Linear ball bearings consist of different materials due to their design and the individual components. MISUMI uses high-quality materials to achieve the longest possible service life. The following materials are available:

- External cylinder: stainless steel (stainless steel) ~56HRC, steel with ~58HRC
- Ball: stainless steel (stainless steel), steel
- Ball cage: plastic, stainless steel (stainless steel)
- Housing: aluminum, stainless steel (stainless steel), steel
- Seal: nitrile rubber

You can find more detailed material information in the tab Technical Drawing.

Coatings

To protect linear ball bushings from corrosion, the surface can be chemically nickel-plated.

As an alternative to a chemical nickel-plating, ball bushings can also be coated with LTBC. The LTBC coating (Low Temperature Black Chrome Platinum) is a surface treatment that protects against corrosion and has low reflection. The coating consists of a 5 μm thick chrome ceramic layer with fluoropolymer infusion and it deposits as a black film. In addition, the LTBC coating is crack-proof and interchangeable and is therefore resistant to delamination due to extreme or repeated bending. LTBC-coated linear ball bearings are thus particularly suitable for locations where corrosion or light reflections are undesirable.

Note: the inner wall of LTBC coated linear bushing units is not surface treated.

Instructions for Use / Installation Information - Linear Ball Bushings

Instructions for use

- MISUMI linear bearings should be used in conjunction with MISUMI linear shafts.
- We recommend using a hardened linear shaft in the g6 tolerance.
- An additional hard chrome plating of the linear shaft makes it more wear-resistant.
- When installing ball bushings in housings, we recommend an H7 housing tolerance. Too close a tolerance will reduce the internal contact travel [dr] to the shaft and can lead to increased wear and premature failure.
- The utilisation of two ball bushings on a steel shaft improves the shaft guide in a system. However, if the angular errors are too high, a self-aligning linear ball bushing should be selected.
- When utilising two linear shafts, the drive should be centred in the system to avoid unnecessary stresses/lever effects.
- The service life, also called nominal service life, should be calculated using the present load case. Here you can perform your service life calculation.
- Depending on local conditions such as temperature, humidity and gases, a variant made of stainless steel or an LTBC coating is recommended.
- When the linear shafts bend sharply, a self-aligning/self-adjusting linear ball bushing should be selected.

Installation Information

General installation instructions for linear ball bushings and linear shafts

MISUMI linear ball bushings should be used in conjunction with MISUMI linear shafts (hardened, tolerance g6).

MISUMI tolerance range: inner diameter linear ball bushings (LMU) and outer diameter linear shafts (SFJ).

General installation instructions for linear ball bushings and housings

MISUMI linear ball bushings should be used in conjunction with MISUMI housings (tolerance H7).

MISUMI tolerance range: outer diameter of linear ball bushing and inner diameter of housing.

Standard linear ball bushing installation instructions

1. When installing standard linear ball bushings, you can use the following locking means: retaining rings (clamping rings), stoppers

(1) retaining rings, (2) housing, (3) stopper/LMST fixing plate

2. Ball bushings are not suitable for rotary motion and applications requiring repetitive insertion and removal of linear shafts. Such a misuse of the linear ball bushing could damage the recirculating ball bushing.

3. Simple linear ball bushings are not suitable for large torque loads (offset load/lever effect). The use of double or multiple linear bushings is recommended for these load cases.

(1) Linear ball bushing with two grooves

4. When assembling linear shafts, forceful slanted insertion into the linear ball bushing can cause the ball cage to bend and the balls to fall out. Be sure to centre the steel shaft to the linear ball bushing before inserting the steel shaft into the linear ball bushing.

Installation instructions for linear ball bushings with stopper/fixing plate

Through the stopper plates, the versions can be designed independently of the housing length.

(1) Attachment, (2) linear ball bushing – standard, (3) linear shaft, (4) LMST fixing plate

The stopper plates enable the ball sleeve and linear shaft to be installed flush against the end faces.

Assembly Instructions for Linear Ball Bushings with Flange and Lubrication Unit MX

When fastening the linear ball bushing with the lubrication unit MX, do not insert the housing of the lubrication unit as guide as shown in (2), as this can damage the housing. Instead, use the flange and guide version as shown in (3).

Do not disassemble the linear ball bushing with flange and lubrication unit MX, as this will impair function.

Assembly Instructions for Linear Ball Bushings with Housing and without Cylinder Pin Hole

During interface assembly, centring on the lateral reference surface can be eliminated by means of the cylinder pin holes.

This reduces the machining effort of the upper plate to be mounted on the block.

Maintenance - Linear Ball Bushings

General Maintenance Instructions

Grease the rows of balls inside the ball bushing before use. Then grease regularly during use. Grease reduces friction by forming a layer between the balls and rolling shaft surfaces and prevents seizing. Loss of grease and degradation of grease shorten the service life of linear guides.

- Recommended grease: lithium soap grease
- Recommended lubrication interval: every 6 months
*Every 3 months for extended work or every 1000 km. Maintenance intervals vary depending on the application and ambient conditions.

Lubrication

Linear ball bushings from MISUMI are delivered coated with a corrosion protection oil. Exceptions to this are the designs with lubrication unit MX. After removing the anti-corrosion oil, we recommend lubricating the bearings.

If you select one of the following lubricants in the configurator, you can order pre-lubricated versions. The versions L, G and H are prefilled with grease, whereby L and G offer a strong reduction in particle formation by means of a suitable grease distribution during operation (see quantitative comparison of particle formation below). Lubrication units MX are filled with lithium soap grease.

Assembly of the lubrication unit MX

The lubrication unit MX is equipped with a fibre insert with lubricant. The capillary effect allows the lubricant to be properly applied to contact surfaces. For this purpose, a constant oil film is formed between balls and steel shaft, which significantly prolongs the lubrication intervals.

Properties of the MX lubrication unit

Longer maintenance intervals: the long-lasting lubricant performance leads to a significant reduction in maintenance, especially in machine and equipment environments where lubrication is difficult to achieve.
Environment: the MX lubrication unit helps reduce lubricant consumption and thus protects the environment.
Cost benefit: it contributes to reducing maintenance costs and failure rate caused by failing to lubricate.
Less effort: it is not necessary to refill the lubricant prior to use, since the ball parts are already filled with a lithium soap-based grease in addition to the lubrication unit.

Comparison test of linear ball bearings and linear ball bearings with lubrication unit

Test conditions:
- Sample: linear ball bushing LMU12 with rust protection oil and linear ball bushing with lubrication unit LMU-MX12
- Effective load: 206N (50% of the dynamic load rating of 412N)
- Average speed: 42 m/min (0.7 m/s)
- Stroke: 100 m
- Lubricant: lubricating grease, only initial filling (only LMU-MX12)
- Shaft material: EN 1.3505 Equiv. (58HRC)
- Duration: 24-hour continuous operation
*The above test conditions serve only as reference values and cannot be considered as a manufacturer warranty.

Test result:

With an effective test load of 50% of the load-carrying capacity of 412N, the design with the MX lubrication unit could achieve a continuous output of 2.5-fold longer than with no MX lubrication unit.
*Since the 2007 catalogue, the data have been updated after the safety limit has been confirmed by further data from test results.
