Torsionally-Stiff Couplings HFD with Through 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.
