Needle Roller Bearing

Needle roller bearings are roller bearings with cylindrical rollers. The rollers are both thin and long relative to their diameter. This type of roller is called a needle roller. Despite the small cross-section, the bearing still has a high load bearing capacity. The needle roller bearing is equipped with thin and long rollers, so the radial structure is compact, and its inner diameter size and load capacity are the same as


BCHH Needle Roller Bearings are precision-engineered components designed for applications with high 

radial load requirements and limited space constraints. Utilizing our 20+ years of specialized manufacturing

 expertise and ISO 9001 certified quality systems, these bearings feature small-diameter rollers with high 

length-to-diameter ratios, providing maximum load-carrying capacity in minimal radial space. 

Manufactured from high-carbon chromium steel with precise heat treatment and surface finishing, they 

deliver exceptional durability, smooth operation, and reliable performance in compact design applications.


Applications:

Automotive transmissions and rocker arm pivots

Industrial gearboxes and small reducers

Agricultural machinery implements

Construction equipment joints

Motorcycle engines and power transmission systems

Packaging machinery and automation equipment
