Inch Open Type C Thin Section Bearings

The C-Type, radial contact ball bearing is designed with deep ball grooves to withstand high loads. Although this bearing is used primarily in applications with radial loads, it can withstand moderate axial loads, reversing axial loads, and moment loads.

Contact Silverthin™ for radial bearing use with combined radial loads, with axial or moment loading, and for limiting speeds and separator selection.
