Product Introduction of ROEMHELD Block Hydraulic Cylinder B1.553
Product Overview
Two hydraulic connection configurations are available: threaded side port variant for direct hose connection and manifold mounting variant with O-ring sealing for modular hydraulic fixture blocks. Optimized low-leakage sealing assembly delivers consistent performance under continuous CNC machining environments.
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.

Non-Magnetic Bronze Housing Design
Bronze alloy prevents magnetic shielding. The permanent magnet fitted on the piston can reliably trigger external magnetic sensors, avoiding signal failure issues encountered with steel cylinder bodies.
Freely Adjustable Magnetic Sensor Position
Continuous dovetail grooves on two sides support sliding sensor installation. Switching points can be set anywhere along the stroke, enabling flexible detection of intermediate positions instead of only end positions. Sensors can be mounted on either side of the block according to fixture layout.
Bidirectional Hydraulic Actuation
Extension and retraction movements are both hydraulically driven. No reliance on return springs, providing stable cycle speed, repeatable timing, and generating both clamping push force and pulling force for complex automated fixture sequences.
Two Flexible Hydraulic Connection Options
- B version (threaded side port): Direct hose connection, suitable for fixture retrofitting and independent unit arrangement.
- K/L version (manifold mounting): Flush installation onto hydraulic manifold blocks, realizing concealed oil circuits for compact multi-station modular fixtures.
Excellent Corrosion Resistance
Bronze housing offers superior corrosion resistance compared to standard steel block cylinders, suitable for environments with heavy mist of coolant and humid workshop conditions.
