Locking Devices 

SIT-LOCK® units are suitable to connect any type of hub (flywheels, pulleys, chain wheels, gears, levers, eccentrics, couplings, etc.) and can be utilized in a varied range of industrial applications.

Features

TRASCO Couplings 

TRASCO® coupling is the flexible and omocinetic coupling that assures the best performance in relation to the physical space occupied in its class. It has a very compact design and allows safe power transmission by absorbing peak loads and torsional vibrations. Moreover, the elastic design of the polyurethane gear ring compensates for angular and radial misalignments and also absorbs small shaft length variation. 

SITEX  Coupling

SITEX® toothed couplings consist of two toothed steel hubs, which are connected with one internally toothed sleeve manufactured from stabilized 6.6 super polyamide resin. 

Universal Joints 

High precision universal joint, complying according with DIN 808/7551.

Every execution is made by 2 hubs with forks and a central block.

Between pins and bores there are:

In the central blocks of P and E series there are the holes for the lubrication.

For the H series (high-speed applications) no lubrication is needed, because the roller bearing are maintenance free.

P series joints is designed for high precision and lifetime applications.

Every execution can be supply with extensible shaft.

V-Pulleys 

V-pulleys according to DIN2211–ISO 4183 (except C type ) suitable for standard application for use with the belt types SPZ – SPA – SPB – SPC (ISO 4184 DIN 7753/1), classical Z – A – B – C (ISO 4184 DIN 2215) and American Narrow 3V – 5V – 8V (RMA-MPTA)

SIT taper bushing 

SER-SIT® taper bushing is designed to give the following features.

Features

Rapid dismantling of the pulley and other transmission equipment; No special tools requirement except hexagonal key.
