Gothic Arch Track Roller - R18EG
Gothic Arch track roller bearing from the PBC Linear inch-series track roller lineup, featuring a 0.375in bore and a 1.21in maximum outer diameter. The roller's outer race is ground with a Gothic arch (four-point contact) profile, allowing it to ride smoothly and self-align along a hardened steel shaft or raceway rail. Built in 52100 chrome bearing steel, it is sized as a direct fit for compatible Redi-Rail® carriages, and is equally suited to custom cam or track roller assemblies.
