Torsionally-Stiff Couplings HZ with Blind Holes (Part Numbers)

Volume Discount

Material: Hubs made from aluminium alloy with iridite NCP finish.
Sliding disc made from 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 torque rings. Positioning drives, position encoders and incremental or absolute encoders, pumps etc.
Temperature range: -20ºC to +60ºC.
