Namura Needle Bearing – 16x21x19.5

Namura Needle Bearings are high-performance top-end piston bearings engineered to handle high RPM and heavy engine loads. Commonly used in motorcycles, ATVs, and snowmobiles, they are manufactured from durable SCM415 chromoly steel and feature a silver-plated cage for improved heat resistance and reduced friction.

Features:

• SCM415 chromoly steel construction.
• Carbon nitriding treatment improves fatigue strength while enhancing heat dissipation.
• Copper-coated and silver-plated to reduce friction and help prevent seizure under extreme conditions.
• Specifically built for top-end piston and wrist pin applications in high-stress, high-RPM engines.
