Product Description

The INA IR17X20X20,5-XL is a cylindrical inner ring designed for use with needle roller and cage assemblies or drawn cup needle roller bearings running directly on a hardened raceway.

By using a separate inner ring, you:

• Avoid grinding or hardening the shaft
• Obtain a high-quality, hardened raceway for the needle rollers
• Improve bearing life and running accuracy

The X-Life (XL) execution offers optimized surface finish and geometry for reduced friction and increased load capacity.

Typical Applications

• Needle roller and cage assemblies
• Drawn cup needle roller bearings without inner ring
• Gearboxes
• Automotive and industrial transmissions
• General machinery where the shaft cannot serve as the raceway
