Torsionally-stiff coupling HZ with blind hole bore 4mm max. torque 0.5 Nm outside diameter 12.7mm
Material: Hubs to outside-Ø 12,7mm made of brass, bigger hubs made of aluminium alloy with iridite NCP finish. 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. Temperature range: -20°C to +60°C. 1) Operating factors (without shaft displacement): Load Period - Operating Factor short term - 1 1 hour per day - 2 3 hours per day - 4 6 hours per day - 6 12 hours per day - 8
