GCR15 AE Roller Type One-Way Backstop Clutch is a robust and reliable mechanism manufactured from GCR15 high-carbon chromium bearing steel. Utilizing a roller-and-ramp design, it permits free rotation in one direction while instantly and rigidly locking to prevent reverse motion in the opposite direction. Primarily installed on high-speed shafts, it serves as an essential safety component in systems like scraper conveyors and reducers to ensure operational stability and prevent equipment backdriving.

Product Detail

Product Description:

Type AE is a roller type freewheel non-bearing supported. Bearings are required to support axial and radial loads. Lubrication and sealing must also be provided by the installation. Nominal outside diameter is a standard ball bearing dimension.

A typical arrangement is to install this type beside a bearing with the same housing diameter tolerance.

The inner race is keyed to the shaft. The outer race has a h6 tolerance and should be fitted in a housing with a K7 tolerance. Additional side notches provide for positive torque transmission.

If the housing tolerance is to R6, use of the notches is not necessary, but the housing must be strong enough to not expand after assembly.
