SIT TRASCO ES GESAP Hubs (Shrink)
GESAP shrink hubs are parts designed for SIT TRASCO ES zero-backlash shaft couplings. They are sometimes called GES AP series TRASCO ES hubs.
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 GESAP hubs are made of steel with an integrated clamping tapered element with a finished bore according to DIN 69002.

Shaft Coupling Construction
- GESAP shrink hubs with an integrated clamping tapered element with a finished bore according to DIN 69002
- Elastic star-shaped element
Typical Applications
SIT TRASCO ES zero-backlash elastic couplings with GESAP 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.
Properties
- 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
