TEN-SIT® 2.0 is a new electronic gauge, used for the correct tensioning of all types of belt drives. Its operating principle is based on the relationship between belt tension and the vibration frequency of the belt itself. TEN-SIT® 2.0 is able to accurately measure the tension of any belt due to its flexible microphone, filtering undesired noise. Benefits Handy and versatile Suitable for any kind of belt New sensitivity range 8 ÷ 600 Hz

SIT-LOCK® self locking units, made of hardened and tempered steel, allow machine parts with round bore to be locked on shafts.

SER-SIT® taper lock bush is designed to give the following: 1) perfect assembly; 2) rapid dismantling of the pulley and other transmission equipment;   3)no special tools requirement except hexagonal key.

The SIT VARIO belts are used for high power transmission on variable speed drive systems. Belt characteristics Wide range of sections and lengths Temperature: -30/+75 °C Tensile members: Flexten® (similar performances to Aramid) Compound: Chloroprene Oil, ozone and abrasion resistance Variable Speed Pulleys – VAR The variable speed pulley is a well established drive; designed to give continuous speed variation at a comparative low cost. Unfortunately, it is well known that this design is subject to excessive flange wear due to the type of drive systems employed. The hub is made from induction hardened steel, hard chrome plated and ground to give uninterrupted slide fit with flanges. Keys are not used with this application. Moving flanges give a wide contact area therefore eliminating uneven belt pressure. The pulley flanges are coupled by means of nylon (6,6) sleeve couplings to the outside of the flanges and by two flats machined on each end of the pulley hub. Two springs situated inside the nylon coupling give the desired pressure. Fixed Pulleys Fixed driven pulley have been specifically designed to be used with VAR pulleys. They are manufactured in grey cast iron (GG20 -GG25) and are treated with a black manganese phosphating process.

  SITEX® ST couplings are fully manufactured in high quality steel. The special OPTIGEAR profile, allows very high torque transmission and the compensation of axial, angular and radial misalignment.  

SITEX® FL gear coupling, made of a steel hub and a Nylon flange fibreglass reinforced,with high mechanical resistance and dimensional stability at different operating temperatures.   SITEX® FL gear coupling is tipically used to connect the engine flywheel to different “end users” such as hydraulic pumps, blade and piston air compressors.   Couplings can be supplied according to ATEX DIRECTIVE 94/9/CE. "Equipment and protective systems, which may be used in areas endangered by potentially explosive atmospheres".

Gear coupling with nylon sleeve, torsionally rigid, double cardanic.  

SIT BANDED belts are built with strong Polyester tension members. This provides the high-strength, high-horsepower rating capacity needed to effectively transmit drive power. SIT BANDED belts are available in a cut-edge construction with cogs for increased flexibility and heat dissipation or envelope construction for drives where pulsation, shock loads, high tension, and long centers are involved.  

SERVOPLUS® bellow couplings are the perfect coupling in all servo motor applications where high torsional rigidity, truly backlash free torque transmission, low inertia and superior reliability are required. The innovative modular system allows quick delivery and competitive cost advantage. Features: backlash free for highest torque transmission precision low moment of inertia excellent dynamic characteristics, for superior drives at high speed and torque inversions allow for axial, radial and angular misalignment easy mounting high torsional rigidity wear and maintenance free working temperature up to 300 °C innovative modular execution

SERLOCK® is the innovative and patented locking device, joining Taper Bush versatility with common self locking unit advantages.Suitable for taper bores 1108, 1210, 1610, 2012, 2517, 3020.  

Shaft version. The shaft is of variable length and can be delivered in welded aluminium or steel.

SIT offers a vast range of ball joints, spherical terminals and spherical joints in order to cover the widest range of uses in the industrial field.  ESBAL® spherical joints are used everywhere it is necessary to transmit movement between elements that have variable angles between them, in the case of levers, drives, hydraulic or pneumatic cylinders. These elements are in wide, general use, enabling a reduction of construction costs and aiding mounting in all cases where a system’s mechanical parts are subject to variable geometries or rotary motion at limited speed.
