Product Overview

The P-PAJ502601KD Needle Bearing is a premium, industrial-grade rolling element component manufactured to match strict Kawasaki OEM specifications. Specifically optimized as a rear drive shaft needle bearing, it is engineered to support rotating components inside heavy-duty hydraulic pumps, most notably the Kawasaki K5V80 series pump assembly. This bearing utilizes high-density cylindrical rollers that drastically reduce friction, limit operating temperatures, and withstand intense radial load spikes within highly confined mechanical footprints. It serves as a critical direct-fit replacement component vital for eliminating shaft play, preventing internal system vibration, and extending the service life of excavator oil pumps and travel drive systems.
