Shaft Coupling Description
TRASCO 55/70 GRMP (GRMP55/70A) - Hub (Type A, Unbored, Cast Iron) is a part designed for SIT TRASCO shaft couplings. It is made of gray cast iron.
SIT TRASCO are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and a polyurethane element. They transmit torque through pressure-stressed elastic star-shaped buffer which absorbs shock and torsional vibration. These GRMP hubs are made of steel or cast iron in short or long version with a seating or in straight design as unbored. They are therefore supplied as semi-finished products and the bore must be adjusted before mounting the coupling on the shafts.
GRMP hubs are sometimes simply called as the TRASCO GR series basic hubs, or labeled as GR P or GR MP.
Shaft Coupling Construction
- GRMP type A (with a seating) unbored hub
- GRMP type B (straight) unbored hub
- Elastic star-shaped element
Shaft Coupling Fields of Use
SIT TRASCO elastic couplings with GRMP hubs are intended for the highest performance in a wide range of industries.
They are particularly applied in compressors, pumps, conveyors and construction machinery. From small precision instruments to heavy duty conveyor drives and packaging machines in the food, chemical, glass, paper, wood and rubber industries.
Shaft Coupling Characteristics
- High transmitted power
- Small size, compact version
- Polyurethane elastic element allows the compensation of angular, axial and radial transplanting
- Possibility of settlement of length shafts deviations
- Couplings areresistant to oil, chemicals and high temperature
