The principle: Ingeniously simple, simply ingenious

For over 50 years, the KOSTYRKA principle has enabled top performance in modern machine tools and fixtures. KOSTYRKA® clamping sleeves are holding round machine elements such as shafts, bolts, spindles or quills and enable extremely high holding forces and short cycle times despite their compact size.

The heart of all KOSTYRKA® clamping sleeves is a flexible base body made of a metal-plastic composite. Once installed, they enclose the part to be clamped and hold it in place by applying hydraulic pressure. A particularly interesting feature of the KOSTYRKA principle is that the oil pressure is converted into an extremely high, radial clamping force without any loss or reaction. A unique feature is the full-surface application of force to the part to be clamped. Once the oil pressure is released, the sleeves spring back into their original position and release the previously clamped part. With this frictional connetion, the surfaces of the parts to be clamped are not damaged.

Focus on customer requirements

Depending on the application, a basic distinction is made as to whether the clamping sleeves require a flange or not. While clamping sleeves without a flange can only absorb axial forces, sleeves with a mounting flange are able to absorb both axial forces and torques.

At KOSTYRKA, partnership with the customer means finding individual solutions and supporting development processes right from the start - which is why clamping sleeves are often custom made. Based on customer specifications, KOSTYRKA can create almost any solution required.

KOSTYRKA® clamping sleeves are currently available with internal diameters from 6 (0.25 in) to over 2,000 mm (80 in) and lengths of up to over 900 mm (35 in) for operating pressures of up to 600 bar (8700 psi). KOSTYRKA is also happy to work with the customer and expand into other dimensions.

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.

CLAMPING SLEEVES WITHOUT A FLANGE - STANDARD ­DIMENSIONS

Clamping sleeves without a flange are able to absorb axial forces.

KOSTYRKA has standardized 20 sizes, from 10 mm (0.39 in) diameter to 150 mm (5.9 in) diameter.

CLAMPING SLEEVES WITHOUT A FLANGE - CUSTOMIZED DIMENSIONS

Clamping sleeves without a flange are able to absorb axial forces. Customized sizes start at a diameter of 6 mm (0.25 in) and currently go up to a clamping diameter of over 2000 mm (80 in).

CLAMPING SLEEVES WITH A FLANGE - CUSTOMIZED DIMENSIONS

Clamping sleeves with a flange are able to absorb both axial forces and torques. For this purpose, the sleeve is screwed on to the customer's housing via the flange. Flange sleeves are always designed to customer specifications. The dimensions start at a diameter of 6 mm (0.25 in) and currently go up to a clamping diameter of over 2000 mm (80 in).

CLAMPING DEVICES - CUSTOMIZED DIMENSIONS

Clamping devices usually consist of a clamping element (clamping sleeve with/without a flange or a special development) and a customer-specific housing. The advantage of such a solution is simple integration by the customer. A clamping device is supplied fully assembled and tested on request.
