Shaft Coupling Description
TRASCO ES 12 GESM (GESM12F5) - Hub (d = 5F7, Al Alloy) is a part designed for SIT TRASCO ES zero-backlash shaft couplings. It is made of aluminium alloy.
SIT TRASCO ES are torsionally flexible, puncture-proof shaft couplings with two metal hubs with front claws and a polyurethane element. They transmit torque through a high-precision pressure-stressed elastic star-shaped buffer which absorbs shock and torsional vibration. The hubs are manufactured with minimal backlash so that the flexible elements are very tightly inserted into the front teeth to make a so-called zero-backlash coupling. These GESM hubs are made of steel or aluminium alloy with a clamping joint and tightening screw.
GESM hubs are sometimes called GES M series TRASCO ES hubs.
Shaft Coupling Construction
- GESM clamping hubs with a clamping joint and tightening screw
- Elastic star-shaped element
Shaft Coupling Fields of Use
SIT TRASCO ES zero-backlash elastic couplings with GESM hubs are intended for the highest demands in a wide range of industries where the highest precision and minimum backlash are required.
They are used, for example, in machine tools, testing machines, fine mechanics, dynamometers and many other applications, particularly in the food, chemical, paper, metalworking and automotive industries.
Shaft Coupling Characteristics
- Torque transmission without backlash
- Vibration damping from the motor shaft (up to 80%)
- Easy and quick installation
- Couplings are resistant to oil, chemicals and high temperature
- Small size, low moment of inertia
