Bore & Shaft Adaptors

Bore & Shaft Adaptors

Several EPC Accu-Coder™ thru-bore and hollow bore models use interchangeable bore adaptors. These allow the encoder to be applied to shafts of varying diameters. Bore adaptors made of Ultem 1000 composite material provide a measure of thermal and electrical isolation as well.  EPC also offers specialty shaft adaptors for selected servo motor applications. Bore adaptor kits allow for field replacement when needed.
