[Application Features] JDB-5 steel base inlaid bearing, is reinforced products, with high compression performance, at work can discharge lubricant particles that produce a membrane between the shaft and sleeve, played a ratio of monomer more resistant to bite lubrication advantages, especially adapted to the lifting machinery support site. [Applications] For example: Roll field machine support, crane support, but should not be used in water or acid occasions. The main parameters Bearing Base material: GCr15 Dynamic load limit: 250N / mm2 basic hardness: HRC58 ~ 60 friction coefficient μ: <0.17 Maximum sliding speed: 0.1m / s maximum operating temperature: 350 ℃ Limiting PV value: 2.5N /mm2.m/s
