Hydraulic Cylinders

ROEMHELD G 2.140 Magnetic Sensors for Position Monitoring of Block Cylinders and Pneumatic Swing Clamps

• Block cylinder with bronze housing B 1.553
• Block cylinder with aluminium housing B 1.554
• Block cylinder with guide housing B 1.738
• Pneumatic swing clamp J 7.202

Electronic magnetic sensors allow position monitoring of the pistons of cylinders with non-magnetisable housings (aluminium or bronze).

An annular permanent magnet is fixed to the piston, and its magnetic field is detected by an electronic magnetic sensor. The magnetic sensors are fixed outside in the lengthwise slots of the cylinder body. The switching points are adjustable by displacement of the magnetic sensors in the lengthwise slots of the body.

ROEMHELD B1.7384 RM Mini Slide: with optional position monitoring, double acting

• Operating pressure 500 bar maximum
• Piston diameter ranges from 25 to 50 mm
• Rod diameter ranges from 16 to 32 mm
• Stroke ranges from 20 to 100 mm
• Maximum push force: 24.5 - 98.5 kN
• Diameter of the guides: 8 - 16 mm

This RM mini slide is a compact block cylinder with 4 integrated guide rods which are also in the position to compensate side loads and moments. Threads can be provided in the front block for fixing of the working loads or tools. 

ROEMHELD B1.5094 Double-Acting Block Cylinders can be used universally for all hydraulically-operated linear movements including positioning, clamping, supporting, opening and closing.

• Maximum operating pressure 500 bar
• Piston diameter 16 - 200 mm
• Rod diameter 10 - 125 mm
• Stroke 16 - 200 mm
• Maximum push force: 10 - 1570 kN

The double-acting functioning allows a force generation in both axial directions (force to push and to pull). This guarantees a high function safety as well as calculable and repetitive times required for the stroke.

ROEMHELD B1.4301 Threaded-Body Cylinders

• Single acting, spring return, with wiper, short version
• Operating Pressure 500 bar maximum
• 5 sizes available
• Strokes from 4 to 16 mm
• Clamping forces 2.5 to 40 kN at 500 bar

These hydraulic cylinders are threaded directly into tapped holes of a clamping fixture. These are a compact solution and can be used to great advantage in fixtures where space is at a premium. Hydraulic fluid is supplied through passageways drilled into the fixture body, this reducing the use of hydraulic pipework, fittings and hoses. The built-in spring returns the piston when hydraulic pressure is released.

ROEMHELD B1.309 Threaded Body Universal Cylinder: single and double acting

• Operating pressure 500 bar maximum
• Piston diameter ranging from 16 to 63 mm
• Rod diameter ranging from 10 to 40 mm
• Varied stroke ranging from 8 to 100 mm
• Maximum push force ranging from 10 to 156 kN

The threaded-body universal cylinders are delivered with the same piston diameters and strokes as the well-proven block cylinders. Hydraulic connection is exclusively effected at the cylinder bottom by hydraulic tubes or hoses. Sealing of the case-hardened piston rod is made by a tandem sealing with minimum leakage and a wiper.

ROEMHELD B1.2811 Hydro-cylinder without stroke end cushioning

• Double acting
• Operating pressure 200 bar maximum
• Push force 9.8 to 100.5 kN
• Pull force 5.7 to 61.2 kN
• Strokes from 100 to 1000mm

This Hydro-cylinder is particularly suitable for fixture building, direct mounting the cylinder head and accurate centring. It is also available with a front flnage mounting option, this is purchased seperately. For operating conditions, tolerances and other data see datasheet A 0.100.

ROEMHELD G3.800 Contact Bolts in mulitple versions.

• Max. operating pressure 500 bar

ROEMHELD B1.7385 RS Hydraulic Slide: double acting, with 4 guide rods, with optional stroke end control

• Max. operating pressure 250 bar
• Piston diameter: 25 - 100 mm
• Rod diameter: 16 - 60 mm
• Stroke: 50 - 200 mm
• Max. push force: 12.3 - 196.4 kN
• Diameter of the guides: 16 - 50 mm
• Standard or Reinforced version

ROEMHELD B1.5091 Block Cylinders: single acting, with and without spring return.

• Operating pressure 500 bar maximum 
• With and without spring return
• Piston diameter ranges from 16 to 100 mm
• Rod diameter ranges from 10 to 63 mm
• Stroke 8 - 100 mm
• Maximum push force 10 - 392 kN

ROEMHELD B1.450 Hydraulic Threaded Body Cylinders 

• Single acting, spring return with wiper
• Operating pressure 500 bar maximum
• 4 sizes available
• Strokes 8 to 16 mm
• Clamping forces 5.6 to 40 kN at 500 bar

These hydraulic cylinders are threaded directly into the tapped holes of a clamping fixture. They are a compact solution and can be used to great advantage in fixtures where space is at a premium. Hydraulic fluid is supplied through passageways drilled into the fixture body, this reducing the use of hydraulic pipework, fittings and hoses. The built-in spring returns the piston when hydraulic pressure is released. The female threads at the piston rod end is designed to accept a contact bolt.

See datasheet G 3.800 for contact bolts.

ROEMHELD B1.310 Universal Clamping Cylinder: single acting with spring return

• Operating pressure 200 / 500 bar maximum
• Piston diameter ranging from 16 to 63 mm
• Rod diameter ranging from 10 to 40 mm
• Stroke ranging from 8 to 100 mm
• Maximum push force 10 to 156 kN

These universal clamping cylinders are particularly suited for clamping fixtures designed to hold various sizes of workpieces (part families). They can be mounted directly into the fixture wall or installed onto horizontal or vertical mounting brackets which are available as accessories.

ROEMHELD B1.282 Hydro Cylinder with & without stroke end cushioning

• Double acting
• Operating pressure 200 bar maximum
• Push force 9.8 to 100.5 kN
• Pull force 5.7 ro 61.2 kN
• Stroke, refer to datasheet

This Hydro-cylinder is particularly suitable for fixture building, direct mounting the cylinder head and accurate centring. It is also available with front and rear flange mounting options, these are purchased seperately. For operating conditions, tolerances and other data see datasheet A 0.100.
