Hydraulic clamping device B1.481 series

workpiecedouble-acting

double-acting, pull-type with and without centring function clamping for bore diameter 16 to 46 mm max. operating pressure from 50 up to 350 bar The bore clamp is particularly suitable for centring and clamping of workpieces with smoothly machined bores with diameters from 16 to 46 mm and a support surface square to the hole axis. The bore clamp is a combination of a double-acting pull-type cylinder equipped with a segment clamping bushing, which is pulled by a tie rod over a fixed cone. Thereby the segment clamping bushing expands radially to the bore diameter of the workpiece to be clamped. By the simultaneous axial movement the workpiece is clamped onto the hardened support at the housing. The obtainable low-clamping force depends on the factor of friction within the bore and the operating pressure.
