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
