Description: Suitable for high load, high-speed engine crankshaft connecting rod large end needle roller bearings. The KU/KUZ needle roller bearing cage has higher rigidity, with a large and flat outer diameter surface to effectively reduce the contact pressure between the cage and the inner diameter surface of the large end of the connecting rod; this type is designed with more needle rollers than the KT type, therefore it is suitable for extremely high-speed or high-load engines.

Advantages of PEEK Coating:

PEEK coating offer significantly more wear resistance and durability compared to traditional silver or copper-coated bearings. Moreover, debris becomes embedded within the PEEK coating layer, thereby extending the lifespan of connecting rods and crank pins.

The secret behind PEEK Bearings lies in their ability to embed debris within the PEEK layer during engine operation. Traditional bearings often suffer serious damage due to debris getting stuck between the connecting rod, cage, and crank pin, leading to wear on the connecting rod race or even the crank pin itself.
