Clamping sleeve 1008 25 optibelt TB

Product detailed description

The Optibelt TB Taper Bush, designation 1008 25, is designed to effectively secure pulleys and pulleys to the shaft via a tapered connection. This system ensures precise centering and high connection strength, while allowing easy assembly and disassembly. The bush has a bore diameter of 25 mm and a width of 22.3 mm, with a maximum tightening torque of 5.7 Nm.

It is made of high-quality grey cast iron EN-GJL-200, which is known for its durability and vibration-damping ability. This material, previously known as GG-20, provides reliable mechanical properties required for industrial applications. The housing is supplied fully machined, including metric holes and a keyway according to DIN 6885/1 or BS46, which simplifies its integration into existing systems.

Optibelt TB is a universal solution for fastening components in industrial transmissions where fast and flexible replacement is required. Thanks to internationally standardized dimensions, it is possible to easily change the bore diameters without the need to modify the pulley or other components. The design allows for a short installation length and effective axial fixation, which is achieved by the conical clamping principle. This system is suitable for new designs and modernization of existing drives, while allowing the transmission of smaller torques even without the use of a classic key.
