SITEX
®
teeth couplings
Description
SITEX
®
couplings consists of two hubs which are connected with one internally toothed sleeve. The hubs are mad of steel and the
teeth, which are both profiled and section crowned are abtained from milling. The sleeve is manufactured from stabalized 6.6
superpolyamide resin.
Features
SITEX
®
couplings are members of the elastic coupling family range. In an excellent way they compemsate for axial, radial and angular
displacement of the connected shafts. The double cardanic action eliminates the imposition of loads on the shafts, which results from
radial and axial misalignment. The combination of steel hubs with polyamide sleeve makes the coupling maintenance and lubrication
free.
The particular toothed profile prevents contact of tooth edges with sleeve, ensuring long life of the coupling.
Dimensional characteristics
Due to compact dimensions and to their excellent performances, SITEX
®
couplings may be used in a wide range of applications.
Couplings are aveilable from stock, both the standard and the "long" hub execution which entirely covers the motor shaft.

** Values are for complete couplings, amx bore diameter, only.
Performances
Mounting can be in both the horizontal and vertical planes. Installation is simple and quick, which contributes to low installation costs.
The coupling is suitable for operating in temperatures ranging from -25°C to +90°C. For short intervals, temperatures of + 125°C can
be tolerated. Components of the couplings are resistant to all types of lubricants and hydraulic fluids.
