Flexible Shaft Couplings

Flexible Shaft Coupling Description

To attach an encoder shaft to another rotating shaft, a coupling device is needed. Because shaft run-out or endplay can result in excessive loads on encoder bearings, EPC recommends use of flexible couplings designed for encoder applications. It's far more cost-effective to replace a coupling than to replace an entire encoder.

EPC also offers magnetic couplings that can be used for temporary applications, or for attaching hollow bore or thru-bore encoders to large diameter shafts.


Shaft couplings to fit any size bore

Magnetic Shaft Coupling Specifications

For use with Models 260 and 25T. For easier centering on a shaft, a pilot hole is located in the center of the coupling.
