1 Pcs, RNA4905 Needle Roller Bearing Without Inner Ring

Key features

• Adopts integral machined solid outer ring with high structural rigidity, delivers strong radial load capacity, adapts to heavy load and impact working conditions
• Compact structure without inner ring, reduces radial installation space, works directly with properly hardened and ground shaft surfaces
• Made of precision hardened chrome steel, features good wear resistance and mechanical strength, maintains stable performance under continuous heavy load
• Precision engineered cage keeps needle rollers evenly positioned, reduces friction and vibration during rotation, ensures smooth and reliable operation
• Suitable for machine tools, engineering machinery, gearboxes and heavy industrial transmission assemblies, please confirm dimensions before purchase

Manufactured from hardened chrome steel with precision machining, this bearing consists of a solid outer ring, needle rollers and a cage assembly. Since no inner ring is included, it requires matching with a shaft that meets specified hardness and surface roughness standards to achieve expected load-bearing performance and service life. This bearing is widely used in machine tools, engineering machinery, industrial gearboxes, heavy transmission systems and other heavy-duty equipment. Please verify the bore diameter, outer diameter and width to ensure compatibility with your equipment before ordering. Proper grease lubrication before installation is recommended for optimal operation.
