Material: Hubs made of stainless steel 1.4305 (AISI 303).

Sliding disc made of black polyacetal. These 3-part zero backlash couplings provide electrical insulation. They consist of two hubs and a sliding disc. They are versatile and of robust design. Large radial compensation, easy mounting even in confined spaces. Applications: Ideal for stepper motors due to the damping properties of plastic sliding disc. Positioning drives, position encoders and incremental or absolute encoders, pumps etc.
