SIT TRASCO ES Zero-Backlash Couplings
TRASCO ES (zero-backlash) are zero-backlash flexible couplings with a special plastic flexible element, which is very tightly placed in the front teeth of the coupling.
SIT TRASCO ES zero-backlash couplings consist of two steel hubs and a star-shaped flexible element. During transmission, shocks and torsional vibrations are damped.
Couplings Fields of Use
TRASCO ES zero-backlash couplings are used in single-purpose machines, machine tools or in testing technology and fine mechanics.
They are designed for the highest requirements in a wide range of industries, especially for machine tools, testing machines, fine mechanics, dynamometers and many other machines where very small backlash is required.
They are also used in the food, chemical, paper, metalworking and automotive industries.
- Torque transmission without backlash
- Vibration damping from the motor shaft (up to 80 %)
- Low electrical and thermal conductivity
- Easy installation
- Small size, low moment of inertia
- Possibility of using in potentially explosive atmospheres by EG Richtlinie 94/9/EC
- Torque: 0.35 to 190 Nm
