Hollow-plunger cylinder 3.2130 series

hydraulicspring-returnclamping

Manual positioning of the element on the die clamping edge. Clamping by the application of hydraulic pressure to the piston and unclamping by spring force. By means of the T-bolt the die is clamped against the clamping surface of the press ram or bed. Applications • on press beds and rams • on machines and equipments for clamping and locking • when the available space is limited • at environmental temperature up to 120° C Special features • optimum adaptation to the clamping surface by spherical disk • T-bolt, secured against loosening • ideal force transmission • convenient and compact design with gripping surface • clamping force from 60 kN up to 104 kN • large clamping stroke • no interfering edges when inserting the dies • easy retrofit • piston hardened and ground • easy installation • fully resilient stroke limitation Versions • Hollow-piston cylinders with spherical disk for the adaptation to the clamping surface with adjusted and secured T-bolt (alternatively: without or with attached T-bolt) • Hollow-piston cylinders - ”L” design, without spherical disk for the adaptation to the clamping surface. T-bolt attached
