Product Introduction of ROEMHELD Block Hydraulic Cylinder B1.530
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.

Single-Acting Spring-Return Design
Only one hydraulic supply circuit is required. After pressure release, the built-in spring reliably pulls the piston rod back, simplifying manifold layout and reducing hydraulic component costs.
Optional Stroke-End Position Feedback
The block housing reserves installation interfaces for high-pressure proximity sensors. Clamped/unclamped status signals support closed-loop control and safety interlock logic for automated machining lines.
Two Flexible Hydraulic Connection Configurations
- B version (threaded port): Direct hose connection, ideal for fixture retrofitting and standalone arrangements.
- K/L version (manifold mounting): Flush installation onto hydraulic blocks, creating tidy concealed oil circuits for modular multi-station fixtures.
Adjustable Working Stroke
Optional distance bushings can shorten the effective travel without modifying the cylinder body, offering flexible adaptation for workpieces with varying dimensional tolerances.
Robust Anti-Contamination Protection
Integrated rod wiper prevents ingress of coolant and metal swarf. Low-leakage sealing system ensures stable long-cycle performance in harsh milling, drilling and grinding environments.
