Product Introduction of ROEMHELD Block Hydraulic Cylinder B1.590
Product Overview
A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.
A: Well, it depends on the quantity and style of hydrualic cylinders, at least 60 days if we make casting and forging, at least 35 days by maching.
A: Sure, we are the manufacutuer and trading of hydraulic cylinder.
A: Double-Acting-have a port at each end, supplied with hydraulic fluid for both the retraction and extension. Single-Acting-hydraulic fluid enters through
a port at one end of the cylinder, which extends the rod by means of area difference. An external force or gravity returns the piston rod.
A: Sure. Show us the drawing, we will quote for you soonest.
A: Yes, we make and supply a wide rang of hydrualic cylinders as a proffetional manufacture, there are only some kinds of them show on the website. Freely contact us to get more information.

Flat Plunger for Direct Static Backing
No protruding piston rod. The flat top surface of the plunger acts directly as the contact face, eliminating the need for separate contact bolts. Optimized for anti-chatter support of thin plates and thin-walled workpieces to suppress machining deflection and vibration.
Short-Stroke Stabilized Supporting Function
Limited short travel prevents excessive workpiece displacement. Ideal for auxiliary static backing in milling, drilling and grinding processes where rigid fixed support is required.
Freely Adjustable Magnetic Position Detection
Continuous dovetail grooves on both sides allow magnetic sensors to slide and be fixed at any position along the stroke. It enables reliable signal feedback to confirm whether the plunger extends and supports the workpiece, supporting safety interlock for automated production.
Dual Hydraulic Connection Configurations
- B version (threaded side port): Direct hose connection, convenient for fixture modification and independent layout.
- K version (manifold mounting): Flush mounting onto hydraulic manifold blocks to realize concealed oil circuits for compact modular multi-station fixtures.
Simple Single-Acting Hydraulic Circuit
Only one hydraulic supply channel is required. After pressure relief, the built-in spring automatically retracts the plunger, simplifying manifold layout and reducing hydraulic component costs.
