IR 150x165x40 NAF Inner Ring Bearing 150x165x40

Main description

The IR 150x165x40 NAF inner ring is a precision-engineered component designed to provide a hardened raceway surface for needle roller bearings in demanding industrial applications.

This type of component supports the performance of best ball bearings and needle bearing systems by ensuring proper load distribution and reducing wear when the shaft surface is not suitable for direct operation. It is commonly used in heavy-duty systems where durability and precision are critical.

The IR 150x165x40 NAF is a hardened steel inner ring that functions as a raceway for needle rollers, enabling reliable operation under high loads and continuous mechanical stress.

With dimensions 150x165x40 mm, this inner ring is intended for large-scale industrial machinery where high load capacity and long service life are required.
