Description/Basics

Bearing housings are highly robust and allow for easy and quick assembly. They are used to accommodate rotating machine elements in mechanical engineering. The housing bearings are generally provided for receiving rotary shafts or torsional shafts. Bearing housing types include pedestal bearings, flange bearings, tension bearings, and pillow blocks. They can be fitted with simple ball bearings. However, there are bearing housings in which angular contact ball bearings are installed that can also absorb axial forces. Housing bearings are available with single-row, double-row and three-row deep-groove ball bearings or angular contact ball bearings. The different designs of the bearing housings can be used horizontally or vertically. For horizontal mounting, MISUMI offers bearing housings as a vertical pedestal bearing in L- and T-shape, as well as a square bearing block. Flange bearing housings, also called flange bearings, are often used for vertical mounting. A bearing unit from MISUMI, whether a pedestal bearing or a flange bearing, is available in double or triple bearings (with rolling bearings) to absorb any lever forces.
The ball bearings are secured in the bearing housings with retaining rings or bearing covers. The bearing can thus be replaced as needed.

Two-row and multi-row bearing housings

Multi-row bearing housings are well-suited for applications subjected to lever forces. They can contribute to increased rotational stability as a flange bearing housing or a pedestal bearing housing.
The flange bearing with angular ball bearing and screwed bearing cover can be used as a fixed bearing. In this case, a floating bearing is recommended in the assembly group.
The combination of fixed and floating bearings can ensure length compensation. This prevents an undesirable compression of a shaft or a threaded drive. A compression can create an imbalance and thus vibrations in an application and lead to inaccuracy

Example of double row flange bearing - three row flange bearing - flange bearing housing with grooved ball bearing - flange bearing housing with angular ball bearing - bearing with housing

Example – multi-row bearing housing – (1) deep groove ball bearing, (2) flange bearing housing, (3) bearing cover, (4) bearing cover screw, (5) angular ball bearing, (6) spacer sleeve, (7) spacer sleeve for inner ring

Ball bearing seals for bearing housings

ZZ (2Z): double encapsulated
VV (2RZ): contactless rubber seal
DD (2RS): contact rubber seal (slightly increased friction)

Areas of Application

MISUMI’s bearing housings, flange bearings and pedestal bearings can be used in almost all applications. Bearing housings are often used as flange bearings or pedestal bearings for the bearing of ball screws and rotary shafts. In addition, they are often found in conveyor belts, or in the bearings of shafts in timing belts, as well as chain transmission. As a fixed and floating bearing, the bearing units can withstand high loads and speeds of rotation. In addition, the encapsulated or sealed bearings are protected from external influences.

Materials

Bearing unit housings are available in steel, stainless steel, and aluminum. Due to the alterations of selecting the ball bearings, a pedestal bearing housing or flange bearing housing can consist of various types of materials. The bearing housings are optionally installed with steel or stainless steel ball bearings. In addition, a bearing housing that can be used as a fixed bearing can additionally be provided on the bearing housing with a rubber seal.

Coatings

MISUMI’s pedestal bearings and flange bearings made of steel can be optionally burnished, painted, chemically nickel-plated. The aluminum bearing housings can be anodized to provide the best possible protection against corrosion depending on the need or the environmental conditions.

Dimensions

Types of pedestal bearings

Shape	Mounting method	Features
T-shape (extruded)		- economically extruded housing - up to 30% less expensive than milled housings - higher security thanks to rounded corners
T-shape		- stable despite its narrow design - available for high positioning accuracy with groove - optionally with lubricant for low particle formation
L-shape		- Low width
Block shape (internal thread)		- Fastened from underneath through the internal thread - Compact design for limited installation space
Block shape		- Low assembly height
Straight		- Fastening from the front - Compact design for limited installation space - Offset design with height accuracy +/- 0.02 mm

Instructions for Use / Installation Information - Bearings with Housing

Installation Information

When assembling bearing housings, care must be taken to ensure that they are installed without tension to prevent vibration, noise and damage. The holes or threads on the mounting surface should therefore be positioned as accurately as possible to prevent stresses on the shaft or spindle. In addition, dowel pins in the base plate can be a helpful option. Also, when installing the bearing housings, make sure that the contact surfaces are clean.
In addition, MISUMI offers special types of bearing housings, which have a positioning groove on the underside to predetermine a precise alignment.

Application example – pedestal bearing mounting with dowel pin, pedestal bearing mounting with keyway, (1) dowel pin

The alteration [NA] allows for the bearing housings and ball bearings not to be delivered pre-assembled. This can significantly simplify assembly depending on the assembly procedure.
In some variants with angular contact bearings, the bearings must be greased during assembly.

Flange bearing housing with female thread

MISUMI offers another special form with the flange bearing with female thread. This flange bearing has the advantage that it can be mounted from the front and the rear. This flange bearing housing provides high mounting flexibility and the ability to standardize and reduce the variety of bearing housings.

Application example – (1) Flange bearing housing assembly with female thread, (2) flange bearing housing mounting with counterbore

Bearing housing for axial load

If high axial forces occur, MISUMI offers a special form of flange bearings in the combination of needle bearings for radial forces and axial ball bearings for axial forces.

Application example – (1) bearing housing with needle bearing and BGCT axial ball bearing, (F) load direction

Maintenance

For bearing housings, the installed bearing can be replaced after the service life has been reached. If the bearings are pressed into the bearing housing, it is recommended to replace the bearing together with the housing. The bearing number installed in the MISUMI bearing housing is discernible from the article number of the bearing unit.
Further information about the various application of bearings can be found under the tab More Information.
Note : After determining the bearing number, you can enter it in the search window to determine the load values and specifications of the bearing for the calculation.
