Stitched construction are especially designed for ball screws, shafts, columns and spindles. Our Round bellows have a very stable form and stay perfectly in shape, which makes them suitable for long-term, highly  demanding applications.

Our special design guarantees maintenance free operations. Round bellows joints with flange and/or sleeve are possible. Please indicate the working application position (horizontal, vertical) and the spindle diameter.

The inner diameter of the concertina shall be 10 mm larger than the diameter of the protected  spindle  (shaft).

Standard material is GN 807 (high tensile strength chemical fiber tissue with PU-coating). Temperature resistant from -40^oC/14^oF to +120^oC/274^oF. For use at high temperatures and in an welding application, aluminized fiberglass tissue resistant up to +450^oC/870^oF is used.
