Shaft Couplings - for Stepper and BLDC Motors

Description
Technical Data
Dimensions
Documentation

The Oldham couplings from Nanotec are easy to install due to the efficient design, and can transfer high forces at low shaft displacement. Through the clamp fastening, damage to the shaft is ruled out. A nylon transmission disc dampens noise and provides good insulation properties (3 kV between two shafts) with a potential-free construction.

The couplings from Nanotec are also available without a hub hole for installation by the customer. Always order 2 couplings + 1 transmission disc.

Temperature range-20 °C to +60 °C
MaterialsHub of aluminum alloy 2014 T6
Transmission discNylon 11 (colorless)
Tapped blind holeLength of the parallel borehole ±0.2, boreholes end with 118 ° bevel
