The XRAY 930250 Ceramic Axial Thrustbearing, sized at 5x10x4mm, is designed to improve smoothness and longevity in ball differential systems. This thrustbearing uses Si3N4 silicone nitride ceramic balls noted for their hardness and wear resistance.
Ceramic balls cut friction and vibration versus steel counterparts, which translates to steadier differential action and reduced drag. Their extra-hard composition helps components last longer and supports higher RPM running in demanding setups.
This thrustbearing suits hobbyists chasing consistent, precise differential performance. Whether tuning for club racing or reliable weekend runs, it helps the differential operate cleanly across varied track surfaces.
