Gear and sleeve-finger couplings transmit torque. The device connects shafts located on the same axis. Parts are suitable for stationary and mobile units. This product is capable of transmitting mechanical energy without changing its value. Individuals and heads of service centers buy gear MZ and MUVP couplings in the company Steel Chain LLC. This organization supplies quality products to leading enterprises in the CIS countries.The described construction consists of coupling halves and bushings. A cylindrical drum is used as the body. External teeth are located on the hub. The product is equipped with safety covers with integrated cuffs.Parts are made of high carbon steel grades. The teeth of the product are heat treated. To increase the wear resistance of parts, oil is used. Lubricant is poured into the drum to the bottom of the O-ring.MZ series products are lightweight. The presence of the coupling will not create additional load on the electric motor or ICE. Toothed parts withstand extreme temperature changes. They are able to work both indoors and outdoors under a canopy. High viscosity oil does not freeze even on the coldest winter days.
