Material: Up to D1 = 28 mm hubs made of brass, chromated and
passivated. From D1 = 41,4 mm aluminium alloy with iridite NCP
finish.Torque ring made of black polyacetal. These unique, zero
backlash, general purpose couplings provide electrical insulation. They
are designed for the lower torque range and offer generous angular and
radial misalignment compensation. Their axial stiffness is unique and
they can anchor unrestricted shafts or perform light push/pull duties.
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. 1) At lower speeds the couplings can compensate up to +/-1 mm
radial and 10º angular displacement. 2) Operating factors: see coupling
