4. Function and application of RU-STEEL type A coupling:
RU-STEEL elastic couplings are made of two equal tooth rings, which mesh in sequence by alternating high-resistance elastic blocks, which operate only by compression. The tooth rings are completely equal and symmetrical in transmission and allow for inflexible coupling in the event of rubber gasket failure, not for long periods of time, without causing damage to the coupled machines.
RU-STEEL Type A couplings have many applications in various industries:
– Pumps: Ensure efficient operation in water pumping systems, wastewater treatment and chemical pumping.
– Compressors: Connect and transmit force between the motor and the compressor, suitable for air compression and refrigeration.
– Cement plants: Ensure quality and efficiency of cement production, withstand large loads and are durable.
