4Pcs B912 Needle Roller Bearings 9/16" X 3/4" X 3/4" Chrome Steel Open End

Description Durable Material: These needle roller bearings are made of bearing steel, undergo surface carburizing and overall hardening heat treatment, and are wear-resistant, high in hardness, with a tough core, allowing them to withstand impact loads without cracking. Hardened Process: Hardened raceways significantly reduce friction and wear, resulting in smooth rotation and extended service life. They can withstand continuous operation under high-speed and harsh conditions. Needle Roller Design: Internal needle rollers feature a closely spaced structure, providing high load-bearing capacity, ensuring precise rotation, stable high-speed operation, while reducing noise and heat generation. Wide Applications: These needle roller bearings are suitable for automotive transmissions, gearboxes, motorcycle clutches, industrial machinery, power tools, agricultural equipment, and a variety of rotating components with limited axial space. Specifications Material: Bearing Steel Process: Hardened Model: B912 Inner Diameter (ID): 9/16" Outer Diameter (OD): 3/4" Thickness: 3/4" Package Content: 4 x Needle Roller Bearings
