Product Introduction of ROEMHELD Block Hydraulic Cylinder B1.542
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 Workpiece Support
The flat plunger surface acts directly as a contact face, eliminating the need for separate contact bolts. Optimized for anti-vibration backing of thin-walled and thin-plate workpieces to suppress machining chatter and deflection.
Short-Stroke Stabilized Backing Function
Limited travel prevents excessive workpiece displacement. Perfect for auxiliary support in milling, drilling and grinding processes where rigid static backing is required.
Dual Hydraulic Connection Configurations
- B version (threaded side port): Direct hose connection, convenient for fixture retrofitting and independent arrangement.
- K version (manifold mounting): Flush installation onto hydraulic blocks for neat, compact modular fixture circuits.
Optional Position Detection Capability
Sensor mounting interface allows fitment of high-pressure proximity switches to confirm whether the plunger is extended and supporting the workpiece, enabling safety interlock logic for automated production.
Reliable Anti-Contamination Protection
Built-in wiper and plunger barrier stop coolant and metal swarf from entering the internal spring chamber, reducing seal wear and extending service life in harsh continuous machining environments.
