WGB650 Solid-self-lubricating Bearings Standard size

Solid-self-lubricating Bearings advantage

1.Can be used without oil.
2.Under high load and low speed, it can still exert superior performance.
3.In places where oil film formation is difficult such as reciprocating motion, rocking motion, frequent starting and stopping, etc., it can still exert superior wear resistance.
4.Superior chemical resistance and corrosion resistance.
5.The design is flexible, simple, convenient, rich in standard products, and can be used with standard shafts.

Precautions for use

1.When possible, try to use standard specifications when designing;
2.Please pay attention to whether there are foreign objects on the surface when assembling;
3.After use, the sliding surface is black or gray due to the oil film formed by the solid lubricant. Please do not scrub and use it as usual;
4.Before assembling, if lubricating oil is applied to the grinding parts, the running-in period can be shortened, which is conducive to mechanical operation and operation;
5.When assembling, it should be pressed in slowly and beating is strictly prohibited to avoid damage to the bearing and cause deformation;
6.When designing, suitable materials should be selected for different parts in order to improve the mechanical performance and extend the service life of the bearing;
7.In high load, reciprocating motion, it is recommended to use screws to fix;
8. When working in fresh water, sea water and at sea, it is recommended to use stainless steel or Chrome-plated surface.
