SIT-LOCK® 8 has a very small axial dimension, is self centering and has been designed to suit various shaft diameters although the overall dimensions are the same. SIT-LOCK® 8 is recommended for applications with medium torques which need a good axial positioning. The limited number of screws make the installation fast.
For the dimension of the product, please download the catalog in the document section.
Shrink discs are external locking devices which are installed over hub projections. By locking the screws, radial pressures act on the hub allowing an effective and solid connection.
Recommended for medium and high torque. For SIT-LOCK® is also available in "SPLIT" and "HALF" for special applications.

Our pulleys can be used for application with a speed up to 35m/s. The pulley dimensions are very accurate as they are manufactured only by means of CNC or automatic lathes.
For higher speed is strongly recomended to use steel as material of construction. Our PBT pulleys are satically balanced according to ISO.
The PT pulleys are not balanced, as they do not have a finished bores.
Here are the dimensions of "PBT" SPA with taper bush 1108 :
- Belt type : SPA
- Taperbush : 1108
- Shaft diameter range : 11 - 28 mm
- Pitch diameter : refer to numbers writen after "PBT" in every product name.
For example, product name : PBT075SPA2 (1108); so, the pitch diameter is 75 mm
- Outside diameter : you can add the pitch diameter with 5.6 to know the length of outside diameter.
For example, the product is PBT075SPA2 (1108); so the outside diameter is 75 + 5.6 = 80.6 mm
- Groove : refer to the last number in every product name.
