The primary application of the flexible detachable couplings of the SPIN type is to connect the electric or hydraulic drive motor to the shaft of the driven equipment. They are recommended wherever it is difficult to disassemble the motor.
A Type "U“ insert can be replaced without disassembling the engine from the drive system. Type SPIN couplings should not be used in drive systems with very large dynamic torque changes due to their simple construction (only the elastic element of Type 'U' is used).
SPIN type couplings tolerate angular misalignment between the motor shafts and the driven equipment well but require more precise radial alignment. They can be used in machinery intended for operation in underground mines of methane explosion classes a, b, c, and coal dust explosion classes A and B, provided that machines equipped with these couplings have undergone EC type-examination.
The primary application of elastic SPIN type couplings is to connect an electric or hydraulic drive motor to a shaft of the driven equipment, such as gearboxes in belt and scraper conveyors, compressors, pumps, fans, and other devices. It is recommended to use them in situations where disassembling the motor is difficult. The Type U insert can be replaced without removing the motor from the drive system."
