Frame-saw tightener for the stone industry, with a protective cap for protecting the sealing bellows at the tightening piston

摘要

Hydraulic frame-saw tightener for cutting blocks of stone, with a double-acting sealing system which hermetically seals the piston circumference from the hydraulic saw tightener by means of flexible bellows which in turn are protected against damage from outside, specifically in both the axial and radial direction of the piston, by a harder protective cap surrounding them.
