NRB roller

BCHH NRB (Needle Roller Bearings) Rollers represent our precision manufacturing capabilities honed over 

20+ years of specialized experience. These through-hardened rollers are manufactured under ISO 9001 

certified processes, utilizing high-carbon chromium steel to achieve superior surface hardness and core 

toughness. With diameter tolerances as precise as ±0.002mm and length-to-diameter ratios optimized for 

maximum load distribution, our NRB rollers ensure reliable performance in high-stress applications while 

maintaining dimensional stability.

Applications:

• Automotive transmission systems and gearbox assemblies

• Industrial robot joints and precision reducers

• Construction equipment pivot points

• Agricultural machinery implement linkages

• Electric power tool gear mechanisms

• Packaging machinery drive systems
