Gothic Arch Stainless Steel Track Roller - R45ECSS
Gothic Arch track roller bearing from the PBC Linear metric-series track roller lineup, featuring a 8mm bore and a 24mm 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 440 stainless steel, it is sized as a direct fit for compatible Redi-Rail® carriages, and is equally suited to custom cam or track roller assemblies.
