Workpiece Clamping Elements

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

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.

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

ROEMHELD B1.733 Position Flexible Clamping Claw double acting, separate locking port, with optional position monitoring, max. operating pressure 250 bar

OBSOLETE ITEM - CONTACT HYQUIP

• Operating pressure 250 bar maximum
• Maximum clamping force is 7.5 kN
• Maximum retention force is 10 kN
• Pendulum range: ±4 mm

The position flexible clamping claw consists of an U-shaped mounting body and the displacably embedded clamping unit with oil supply by two short high-pressure hoses with swarf protection.

ROEMHELD B1.480 pull-type, single and double acting, with anti-rotation device max. operating pressure 500 bar

• Maximum pulling force is 24.5 kN
• Single & double acting
• Clamping stroke, pulling - 6.0 mm
• Operating pressure 500 bar maximum

This Hydraulic Threaded-Body Clamping Module was designed for screwing in into standardized housings, fixture bodies or manifold blocks and fixture base plates or intermediate plates for pallets or machine tool tables. With single and double acting features and anti-torsion device.

ROEMHELD I4.130 Fixture Clamp, Position Flexible max. clamping force 8 kN, jaw width 40 mm double acting, max. operating pressure 250 bar compensate machining forces from all directions.

• Maximum clamping force: 8 kN
• Maximum retention force: 10 kN
• Jaw width: 40 mm
• Clamping stroke: 2x 8 mm
• Maximum flow rate: 17 cm³/s
• Maximum operating pressure 250 bar

This fixture clamp with position-flexible clamping function consists of a very slim basic body with 2 integrated hydraulic cylinders. The piston forces are transmitted by two channels to the two clamping slides that can be moved independently from each other. During clamping both clamping slides contact the workpiece nearly without force.

ROEMHELD I4.120 Fixture clamp, concentric clamping: max. clamping force 6.5 kN and 9 kN, jaw width 40 and 65 mm double acting

• Maximum operating pressure 250 bar
• Maximum clamping force: 6.5 - 9 kN/jaw
• Max. retention force: 8 - 15 kN
• Jaw width: 40 - 65 mm
• Clamping stroke: 2x5 - 2x8 mm
• Maximum flow rate: 70 - 100 cm³/s

The fixture clamp with concentric clamping function consists of a very slim basic body with 2 integrated hydraulic cylinders. The piston forces are transferred via a guided connecting link to the two clamping slides so that a centric synchronism is obtained. All threads and ports are at the bottom to allow a space-saving arrangement of several clamping points in a very limited space.

ROEMHELD H4.305 Concentric Positioning and Clamping Elements 2 and 3-point positioning, double acting, hydraulically operated

• Maximum operating pressure 250 bar
• Clamping Ø: 25 - 177 mm
• Bolt Ø: 12 - 22 mm
• Clamping force at 100 bar: 4 - 17 kN
• Clamping force at 250 bar: 10 - 44 kN
• Clamping repeatability, absolute: 0.02 mm

Workpieces with cast or machined bores, reliefs or break-outs, can be easily loaded to the fixture with the concentric positioning and clamping elements and can be concentrically clamped or positioned for machining. Overstressed conditions can be avoided and clamping can be completely solved by an ingenious combination of 2 and 3-point elements.

ROEMHELD B1.9402 Threaded Body Work Supports: M 30 x 1.5, with metallic wiper edge, 4 sizes, double acting

• Operating pressure 500 bar maximum
• Maximum load force: 6.5 - 9.5 kN
• Plunger stroke: 8 - 15 mm

In the body of the threaded-body 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 support plunger is extended and retracted by means of a small double-acting cylinder. The threaded-body work supports are protected against swarf by a metallic wiper and sealed against liquids.

ROEMHELD B1.8491 Compact Swing Clamps with Sturdy Swing Mechanism: bottom flange, top flange, threaded-body type, double acting

• Maximum clamping force: 2.2 kN
• Rod diameter: 10 mm
• Piston diameter: 14 mm
• Clamping stroke: 8 mm
• Maximum flow rate: 5 cm³/s

ROEMHELD Compact Hydraulic Swing Clamps with Sturdy Swing Mechanism 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 B1.8251 Hinge Clamps: with metallic wiper edge and optional position monitoring, double acting

• Operating pressure 250 bar maximum
• Maximum clamping force: 4 - 21.5 kN
• Usable clamping stroke: 4.0 - 9.0 mm adm
• Fow rate 15.7 - 55 cm³/s

When pressurising the element, the piston moves upwards and swivels the clamping lever over the hinges forwards and at the same time downwards onto the workpiece. The piston force is deviated by 180° and is available as clamping force with virtually no loss of efficiency.
