WGB250 Standard size

Bearing characteristics

WGB250 material provides a self-lubricating solution, combining the wear resistance and mechanical strength of cast iron and the self-lubricating performance of solid lubricants, so that it does not require or less oil maintenance during use; it is especially suitable for high load, low speed and intermittent Used under swing conditions, such as automobile covering film, metal stamping abrasive tools, injection molding machinery and metallurgical equipment, etc.

Product advantages

The products are widely used in high-load, intermittent or swing motions, such as automobile and motorcycle production lines, stamping dies, continuous casting machinery, etc. Compared with WGB650, it has lower production cost.

The main factors affecting life

1:Load P: The greater the load, the shorter the bearing life; in any case, the maximum load cannot exceed the theoretical maximum allowable load value.
2:Speed ??V: The higher the speed, the shorter the service life of the bearing; in any case, the maximum sliding speed cannot exceed the theoretical maximum allowable value.
3:PV value: The working life of the bearing depends on the PV value, that is, the product of the actual load P and the sliding speed V. The smaller the PV value, the longer the bearing life.
4:Temperature: The life of the bearing also depends on the temperature when the bearing is used. The higher the temperature, the shorter the service life of the bearing. Therefore, the heat dissipation characteristics of related components should be considered when designing and selecting.
5:Surface roughness of grinding parts: For grinding parts, alloy steel or hard chromium-plated shafts are used. When the surface roughness Ra=0.4-0.63 range, the service life of the bearing can be significantly improved.
6:Other factors such as the design of the bearing seat and lubrication conditions.
