ROEMHELD B1.4841 Bore Clamps: Block-type, without centring function, double acting, for bore diameter 7.8 - 17.7 mm, max. operating pressure 250 bar

OBSOLETE ITEM - CONTACT HYQUIP

• Double acting
• Operating pressure 250 bar maximum
• Bore hole diameter ranges from 7.8 to 17.7 mm
• Maximum low-clamping force 5.1 - 9.8 kN
• Expansion force , radial: 9 - 14 kN

This bore clamp is a double-acting pull-type cylinder. An exchangeable clamping bushing is fixed to the piston. The four segments of the clamping bushing are radially expanded with spring force by a pyramid-shaped clamping bolt. Thus the expansion force is always the same and independent of the hydraulic clamping pressure.

ROEMHELD B1.530 Block Cylinders: with adjustable stroke end cushioning and optional stroke end control double acting

• Maximum operating pressure 500 bar
• Piston diameter 25 - 100 mm
• Rod diameter 16 - 63 mm
• Stroke 25 - 100 mm
• Maximum push force 24.5 - 392 kN

ROEMHELD B1.459 Threaded Body Cylinder:  single acting with spring return

OBSOLETE ITEM - CONTACT HYQUIP

• Operating pressure 160 / 500 bar maximum
• Stroke 10 mm
• Push force 2.5 kN maximum
• M16 external thread

These threaded-body cylinders allow direct tube or hose connection. Due to elimination of the pipe union a particularly compact assembly results. Depending on wall strength and fixing method (thread or bore) a certain adjustment is possible. The cylinders can also be screwed into threaded bores. Sealing is then effected by the sealing nut available as accessory. By adjustment, workpiece tolerances of more than 20 mm can be absorbed.
