Product Details

Namura Needle Bearing by SPI®. Top-End needle bearings are the key components in transmitting the engine’s explosive force from the crown of the piston to the rotating assembly below. Namura’s bearings are manufactured from SCM415 Chromoly Steel and treated using a process called carbonnitriding; this enhances the fatigue strength and heat dissipating capacity of the cage. The overall bearing structure and high rigidity allows them to withstand the significant stress levels created by varying/high RPM’s and the impact of an engine’s stroke. Another key feature that our bearing assemblies have is a silver coated cage. Yes, the cage that holds our needle bearings is electroplated first with copper and then a second coating of silver to better resist the erosive materials it is exposed to. This coating also decreases the friction between the cage and the bearings allowing for longer assembly life and increased reliability.
