SITEX® gear couplings consist of two toothed hubs which are connected with one internally toothed sleeve. The sleeve is manufactured from stabilized 6.6 superpolyamide resin.
The torsional rigidity of the sleeve prevents angular speed variation. The combination of steel hubs with polyamide sleeve makes the coupling maintenance and lubrication free.
The particular toothed profile prevents contact of tooth edged with the sleeve, ensuring long life of the coupling.
TRASCO® ES is our zero backlash coupling designed to compensate for misalignment and vibration dampening for indexing applications. The compact design of TRASCO® ES makes it the right choice for all precise motion applications.
The TRASCO ES consist of two hubs, which are either made of high-strength aluminium (up to the 38/45 size) or steel (from size 42) that are connected with an elastic element.
