Composed by two half-conical rings, an inner ring and an outer ring. It is particularly suitable for applications requiring a wide tolerance.

Composed of two tapered rings, it is suitable for applications that require smaller dimensions.

Comprised of a cut inner ring and outer ring, and a spacer which prevents the hub from moving in relation to the shaft when tightening the screws. This locking device is particularly suitable for applications which require low hub pressures.

Recommended for use with aluminium hubs or hubs with lower mechanical properties.

Composed of two tapered rings and one outer slit ring. It is particularly suitable for applications that require high torque transmission.

Composed of an inner ring and outer ring both with slits. This type of locking device is particularly suitable for applications that require good hub-to-shaft concentricity and perpendicularity. It is also used for locking hubs with lower mechanical properties.

Clamping bushing with unique cone design. Provides good concentricity and good self-centering. A small axial movement of the hub may occur during the installation operation. They are not recommended for applications that require precise axial positioning with this type of bushing.. The SITLOCK® 6 bushing is recommended for torque applications to transmit media.

Clamping bushing with unique cone design. Provides good concentricity and self-centering. It is recommended for medium torques.The flange design prevents axial movement during installation.It is suitable for applications with medium torques, which require a very precise axial positioning.

Clamping hub with unique cone design. The flanged design prevents axial movement during installation. The SIT-LOCK ® 8 has a very small comparative length, is self-centering and has been designed to adapt to various shaft diameters, with the same external dimensions.

SIT-LOCK® 8 is recommended for applications with medium torques that require good axial positioning. The limited number of screws make installation quick.

It consists of two conical rings and a fixing nut. Its simple design allows an agile assembly/disassembly. SIT-LOCK® 9 is suitable for applications with medium and small torques.

SIT-LOCK® 10 are clamp bushings with double cone design. They offer very easy angular synchronization and axial adjustment of the shaft ends. They transmit high torque and offer a low-cost solution for rigid shaft-to-shaft connection.

Clamping bushings designed for joining hollow shafts with
. By locking the Ballscrews, radial pressures act on the shaft, allowing for an efficient and solid connection
. Recommended for medium and high pairs. SIT-LOCK® 11 is also manufactured in “SPLIT” and “HALF” versions for special applications.

3D Cal12 SIT-LOCK® 12 it is a clamping bushing. Suitable for large quantities in medium torque applications.

The SIT-LOCK ® 13 bushing similar to the standard type SITLOCK ® 9 but with a longer execution. Composed of two conical rings and a fixing nut.

The clamping bushing of the 14 series consists of a single conical ring in difference to the type 11 which consists of 3 pieces.These bushings feature superior concentricity and self-centering and a higher degree of dynamic balance. Suitable for applications with medium-high speeds.
They are manufactured in 5 different variants.

Suitable for servo motors and small diameter pulleys. It generates a capacity of axial force similar to the resistance of the Ballscrews and the axial movement that it generates in the assembly can be used for axial locking of the bearings

Composed of a single cylindrical ring in which a tapered hole is cut. A special screw with a tapered surface is inserted into the tapered hole.
The screw is of quality 12.9 in order to allow the tightening torques indicated in the tables.
