ROEMHELD B 1.9503 Work supports: Top flange type with metallic wiper edge, 3 sizes, 3 types of function, single acting

• Maximum operating pressure 500 bar
• Cross section of the body: 70x50 - 125x95 mm
• Maximum load force: 16.8 - 102 kN
• Plunger diameter: 20 - 50 mm
• Plunger stroke: 12 - 20 mm
• Maximum flow rate: 15 - 100 cm³/s
• Elastic deformation: 1.6 - 3.2 µm/kN

In the body of the work support a thin-walled locking bush is integrated, which locks cylindrically around the freely-movable support plunger when pressurising the element with hydraulic oil. The elements are protected against penetration of swarf by a metallic wiper edge and sealed against liquids. The venting port allows also the connection of positive air pressure protection.

• Maximum clamping force: 2.2 kN
• Rod diameter: 10 mm
• Piston diameter: 14 mm
• Clamping stroke: 6 mm
• Maximum flow rate: 2.5 cm³/s

ROEMHELD Compact Single-Acting Hydraulic Swing Clamps, threaded-body type with top and bottom flange used for clamping of workpieces when it is essential to keep the clamping area free of straps and clamping components for unrestricted workpiece loading and unloading.

ROEMHELD B1.825 Hinge Clamp

OBSOLETE ITEM - CONTACT HYQUIP

• Double acting
• Maximum clamping force: 18 kN
• Maximum operating pressure 200 bar

When pressurising the element, the piston moves from the unclamped position upwards. The clamping lever swivels forward by means of the two links and at the same time downwards onto the workpiece. The clamping lever is provided with an internal thread to accept a contact bolt, which can be easily exchanged. Oil supply is made from the back by means of fittings.

ROEMHELD B1.8233 Block Clamps: Versions with / without self-locking double acting

• Maximum clamping force ranges from 7.5 to 18.5 kN
• Maximum operating pressure 70 / 100 bar
• Clamping stroke: 6 - 8 mm
• 2 sizes available

Block clamps are double acting hydraulic cylinders. The clamping bolt is supported by a ball bearing and can be swivelled. During the linear extending stroke the clamping bolt with the contact bolt is moved above the clamping point and then swivelled onto the clamping point by means of a wedge drive. The version without self-locking has a smooth wedge surface and requires a constantly available oil pressure
