Guide wheel bearings are precision ground, double row, angular contact bearings. These bearings are pre-lubricated and available in either 52100 chrome or 440C stainless steel. Although the standard chrome steel version is available either sealed or shielded, the stainless steel design is available sealed only. The concentric and adjustable bushings provide a simple, effective means of adjusting the free play of the guide wheel system.
