292 TECHNICAL INFORMATION Salt water spray testing method conforms to JIS H8502. Testing Sample: Flanged Linear Bushing Single Type Antirust Performance 46+ &RVJWBMFOU SUS440C &MFDUSPMFTT /JDLFM 1MBUJOH -PX 5FNQFSBUVSF #MBDL $ISPNF 1MBUJOH Before Test 72 hr 168 hr (Ref. Data) Antirust Performance Comparison Test t Low temperature black chrome plating on linear bushings is 5μm of fluoropolymer layer chemically deposited as a black film, and it has a long-lasting rust prevention effect. t Additionally, the coating is resistant to cracking from extreme and repeated bending. t Low temperature black chrome plated shafts are suitable for places where rusting or reflection of light is undesirable. (Note) No surface treatment is applied to I.D. surface of low temperature black chrome plated linear bushings. * Photograph shows the condition of Linear Bushing after Sliding Test (Sliding Test Conditions) 50km sliding test was conducted with a 412N load on the linear bushing. No performance degradation after the test. 2-JOFBS #VTIJOH .PEFMT "QQMJDBCMF UP -PX 5FNQFSBUVSF #MBDL $ISPNF 1MBUJOH Straight "QQMJDBCMF * % TYPE CODE Single LMUR Ø3~Ø30 #LHU Double -.683 Ø5~Ø30 #LMUW Flanged Type "QQMJDBCMF * % TYPE CODE Single LHF∓R Ø6~Ø30 #LHFC Double LHF∓83 #LHFCW * For details, refer to each page. -PX 5FNQFSBUVSF #MBDL $ISPNF 1MBUJOH Linear Bushings: LMUR12 Linear Shafts : RSFJ12 2Grease Performance Item Conditions Unit Measurement Method L Type G Type H Type Thickener - - - Aromatic Diurea Lithium Type Aluminum Complex Soap Base Oil - - - Ether Synthetic Oil Mineral Oil + Synthetic Hydrocarbon Oil USP White Oil Base Oil Kinetic Viscosity 40°C mm2/s JIS K2220 5.19 103 30 105 100°C 12.8 - 11.5 Miscible Consistency - - JIS K2220 5.3 280 207 310 Dropping Point - °C JIS K2220 5.4 <260 200 238 Evaporation Amount 99°Cx22hr wt% - 0.15% 1.40% 0.27%(ASTMD-972) Oil Separation 100°Cx24hr wt% JIS K2220 514 1.2% 0.8% 2.1%(ASTMD-1742) Operating Temp.
