EXPANDING SLEEVES WITHOUT A FLANGE Kostyrka Vietnam

Expanding sleeves without a flange are able to absorb axial forces. Customized sizes start at a diameter of 8 mm (0.32 in) and can go up to a clamping diameter of over 2000 mm (80 in).

Depending on the application, a distinction is made between expanding sleeves with and without a flange. Expanding sleeves without a flange can absorb purely axial forces, while sleeves with a mounting flange are able to absorb both axial forces and torques.

Clamping diameters from 8 (0.32 in) to over 1,000 mm (40 in), pressures up to 600 bar (8700 psi)

The smallest KOSTYRKA® expanding sleeve currently available has an outer diameter (clamping diameter) of 8 mm (0.32 in). The largest expanding sleeve currently produced has a clamping diameter of over 1000 mm (40 in). Operating pressures of up to 600 bar (8700 psi) are also possible. KOSTYRKA is also happy to move into other dimensions together with the customer.

Usually, the clamping sleeves are made of bronze. In special applications, for example for spindle clamping devices or very fast rotating parts, the sleeves are made of steel.
