Hydraulic Cylinders

ROEMHELD B1.462 Plunger Piston with integrated pull-back spring, stroke limitation and fastening screw form a unit that cannot be disassembled.

• Max. operating pressure 250 bar
• Piston diameter: 25 - 50 mm
• Stroke: 8 and 12 mm
• Max. push force: 12.2 - 48.7 kN
• External thread: G1/8 - G1/2

ROEMHELD B1.553 Compact, Double-Acting Short-Stroke Cylinder with very high press and pulling force and adjustable control of the piston position by magnetic sensors.

• Maximum operating pressure 500 bar
• Piston diameter 25 - 63 mm
• Rod diameter 16 - 40 mm
• Stroke 20 - 100 mm
• Maximum push force 24.5 - 155.9 kN

ROEMHELD B1.464 Threaded Body Cylinder: short stroke, single acting with spring return

• Operating pressure 500 bar maximum
• Piston diameter ranges from 20 to 32 mm
• Stroke Options are 4 and 8 mm 
• Clamping Force at 500 bar (5.7 - 40.2 kN)
• M38 - M56 external threads

These short threaded-body cylinders are particularly suitable for recessed installation in clamping bars (see datasheet). Oil supply is made through drilled channels. The plunger construction combined with the wiper avoids penetration of contamination and liquids into the spring area.

ROEMHELD B1.544 Double-acting block cylinders with position monitoring are particularly suitable for automated installations, time and cycle-dependent clamping and unclamping.

• Maximum operating pressure 350 bar
• Piston diameter 25 - 63 mm
• Rod diameter 16 - 40 mm
• Stroke 20 - 100 mm
• Maximum push force 17.1 - 109.2 kN

ROEMHELD B1.470 Threaded Body Cylinder: double acting.

• Operating pressure 500 bar maximum
• Piston diameter ranges from 16 to 40 mm
• Rod diameter 10 to 25 mm
• Stroke ranges from 16 to 40 mm
• Push force 10.0 to 62.8 kN maximum
• M26 - M60 external thread

These double-acting cylinders allow a space saving installation into the fixture body and therefore a hose free oil supply. The double-wiper protects the piston and enables sealing with very little leakage. Sealing of the cylinders in the fit hole is made by two O-ring/support-ring combinations.

ROEMHELD B1.711 Hydro Cylinder with Locking Piston single acting with spring return

• 3 body variants; threaded-body, block and low-block cylinders
• Single acting with spring return
• Maximum operating pressure 500 bar
• Fixtures without tubes are possible

Hydro cylinders with locking piston are singleacting plunger cylinders, similar to the design of the proved threaded-body cylinders as per data sheet B 1.461. When pressurising the element, the piston will be expanded and locked in the cylinder body.

ROEMHELD B1.560 Block Cylinder, with Anti-rotation Piston: aluminium housing for adjustable magnetic sensors, double acting

• Maximum operating pressure 350 bar
• Piston diameter 32 - 50 mm
• Rod profile P3G 22 - 40 mm
• Stroke 25 - 100 mmMax. push force: 28.1 - 68.7 kN

ROEMHELD B1.5601 Built-in Anti-rotation Pistons: Piston and threaded bushing, complete with seals, double acting   Max. operating pressure 350 bar

• Maximum operating pressure 350 bar
• Piston diameter 32 - 50 mm
• Rod profile P3G: 22 - 40 mm
• Stroke 25 - 100 mm
• Maximum push force: 28.1 - 68.7 kN 

ROEMHELD B1.570 Pull-Type Cylinders, Single-Acting with Spring Return.

• Operating pressure 500 bar maximum
• Piston diameter ranges from 16 to 100 mm
• Rod diameter ranges from 10 to 63 mm
• Stroke ranges from 8 to 12 mm
• Maximum pulling force: 6 - 235 kN

ROEMHELD B1.738 Block Cylinder with Guide Housing:  Max. operating pressure 500 bar, extending 500 bar steel block cylinder, 350 bar aluminium block cylinder, retracting 350 bar all versions

OBSOLETE ITEM - CONTACT HYQUIP

• Steel or Aluminium housing
• Piston diameter ranges from 25 to 63 mm
• Plunger diameter ranges from 30 to 70 mm
• Stroke ranges from 20 to 63 mm
• Maximum push force: 17.1 - 156 kN

The hardened clamping bolt is located in a guide housing, and is connected to the flange-mounted block-cylinder by means of a coupling.
