Shaft Coupling Description
TRASCO 55/70 GRMB B1 (GRMB55/70B1) - Hub (Type E, TB 2012, 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 GRMB hubs are made of cast iron with Taper Lock bore in B1 version with external mounting or B2 version with internal mounting.
GRMB hubs are sometimes called as the TRASCO GRB series hubs, or labeled as GR B or GR MB.
Shaft Coupling Construction
- GRMB type B2 for Taper Lock bush with internal mounting
- Elastic star-shaped element
Shaft Coupling Fields of Use
SIT TRASCO elastic couplings with GRMB hubs are intended for the highest performance in a wide range of industries.
They are applied in compressors, pumps and construction machinery. Especially for conveyor systems 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
- Simple assembly without the need to modify the bore
- Couplings areresistant to oil, chemicals and high temperature
