Centering Clamping Elements with clamping balls, operation from the bottom
EH 23340.
To be used for accurate centering and clamping in blind holes of workpieces with locating hole. Exact self-centering with a precision of ±0,025 mm. The clamping balls frictionally center and hold workpieces with raw or pre-machined surfaces down to the bearing points. Large adjustment stroke and a small building height are a feature of this center clamping element.
Mounting from either top or bottom.
Material
