Needle roller bearings are usually grease lubricated, but oil or oil mist lubrication is preferred for heavy duty or high speed applications. Many light duty needle roller bearings never require relubrication, but high loads or high speeds do.

Application: Automobile, Motorcycle, Cycle, Electric tool, Spinning machine, Agriculture machine, Industrial sewing machine, Engineering machinery and etc.

1. High quality raw materials

With world-class high-quality steel and salt bath quenching and hot combing technology, the wear resistance of the material is greatly improved, and the service life characteristics and high core toughness are improved, and the comprehensive durability is improved.

Separate components of the bearings are interchangeable for easy installation, maintenance and disassembly

After the outer ring is quenched by advanced salt bath, it has sufficient hardness to ensure sufficient running life and satisfactory load carrying capacity.

4.High precision rolling element

High-precision rolling body is preferred, which improves the rotation accuracy more effectively, and the accuracy level is P5.
