Centering Clamping Elements with clamping segments, operation from the bottom
EH 23340.
For centering and clamping in blind holes of workpieces with locating hole. Exact self-centering with a precision of ±0,025 mm. Components with raw or machined surface can be centered positively and are pulled down on the contact points due to the ground clamping elements. The centering clamping element is characterised by large setting ranges and a compact construction height.
Mounting from either top or bottom.
