1. Product details:
1). Bore tolerance ISO standard H7
2). Keyway tolerance as per DIN6885/1 JS9
3). Material: cast iron, steel and aluminum alloy
4). Finishing: blackening, phosphate, and zinc plating

 
2. Abstract:
A coupling is a device used to connect two shafts together at their ends for the purpose of transmitting power. Couplings do not normally allow disconnection of shafts during operation, however there are torque limiting couplings which can slip or disconnect when some torque limit is exceeded.

 
3. Features:
1). Widely used in various mechanical and hydraulic fields.
2). No backlash, rigid in twisting direction.
3).High precision in transmission and high rotating speed.
4).The highest applicable temperature is 280 degree
5). Good elasticity, height strength, corrosion resistant, wearable
6). No need to lubricate, quiet operation, no wear or slipping, reducing energy losing
7). Quick and easy mounting and disassembly
8). Small dimension, low weight, high transmitted torque
9). Elastomers made of polyurethane with shore hardness 80-98
10). Compensating the axial relative drift, buffer and vibration reduction

 
4. Applications:
1).To provide for the connection of shafts of units that are manufactured separately such as a motor and generator and to provide for disconnection for repairs or alternations.
2).To provide for misalignment of the shafts or to introduce mechanical flexibility.
3) To reduce the transmission of shock loads from one shaft to another.
4) To introduce protection against overloads.
5) To alter the vibration characteristics of rotating units.
