Product Introduction of ROEMHELD B1.5091 Block Hydraulic Cylinder
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.

Lightweight Aluminium Housing
Aluminium alloy block greatly reduces cylinder weight compared to steel variants, ideal for mobile and lightweight modular hydraulic tooling. Non-magnetic property prevents magnetic shielding, ensuring consistent sensor triggering.
Full-Stroke Adjustable Magnetic Position Detection
Continuous dovetail slots allow magnetic sensors to slide freely. Trigger points can be arbitrarily set along the whole stroke to realise intermediate position feedback, instead of limited end-position detection. Sensors can be installed on either side to suit fixture layout constraints.
Bidirectional Hydraulic Actuation
Extension and retraction are fully hydraulically powered, independent of return springs. Stable cycle speed and high repeatability can be achieved for clamping, pushing and pulling motions in automated production.
Two Flexible Hydraulic Connection Configurations
- B version (threaded side port): Direct hose connection, convenient for fixture retrofitting and independent cylinder layout.
- K/L version (manifold mounting): Flush installation onto manifold blocks to achieve compact concealed oil circuits for multi-station tooling.
Optimised Anti-Corrosion Performance
Aluminium housing offers better corrosion resistance than steel blocks under continuous coolant spray, extending service life in CNC machining environments.
