SIT-LOCK® locking assembly unit consists of four pieces with two inside double-one rings joined through a set of tightening screws. It is recomended for medium torques. Although it is not self centering, it can be easily assembled and diassembled.
SIT-LOCK 14 are shrink discs for external, series "14", are characterised by a single tapered ring instead of opposite tapers of the 3 pieces shrink discs SIT-LOCK series "11". The SIT-LOCK 14 Shrink discs offer a better concentricity and centering and very good balancing. These features make the series highly suitable for mid-high speed applications.
SIT-LOCK 14 are manufactured in five different types :
- 14-21 for mid torque transmission
- 14-22 for high torque transmission
- 14-81 for very high torque transmission
- 14-23 eqivalent in size to the type 14-22 but able to transmit an extra 20-30% of torque
- 14-83 eqivalent in size to the type 14-81 but able to transmit an extra 20-30% of torque
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.
