China OEM Flexible Normex Flange Shaft Flexible Nm Coupling with Rubber PU Element for Air Compressor Parts
The NM flexible shaft coupling is designed to transfer torque through a cylindrical pin made of non-metallic materials, which is placed between two sides of the coupling and the inner surface of the outer ring. The design provides a device to transfer the torque through the column pin to realize the connection between two half couplings. The NM flexible shaft coupling has a slider made of bakelite cloth or polyurethane, which is suitable for high speed, large torque, and no sharp impact of the two connections. The maximum allowable torque is 850N m, and the maximum shaft diameter is 50 mm.
