Product Introduction of ROEMHELD Block Hydraulic Cylinder B1.552
Product Overview
Two hydraulic connection configurations are offered: threaded pipe port variant for direct hose connection and manifold mounting variant with O-ring sealing for modular hydraulic blocks. The heavy-duty steel housing and low-leakage sealing system deliver stable long-cycle performance under continuous CNC machining conditions.
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.

Rear-End Position Detection Architecture
The continuous piston rod extends out from the cylinder bottom. Standard inductive proximity switches can be installed at the rear to detect clamped/unclamped piston positions, solving space limitations when lateral sensor mounting is impossible. Switching positions can be freely adjusted on-site.
Bidirectional Hydraulic Actuation
Extension and retraction movements are both hydraulically powered, eliminating reliance on return springs. It provides consistent cycle timing, stable actuation speed, and generates both clamping push force and pulling force for complex automated fixture sequences.
Two Flexible Hydraulic Connection Options
- B version (threaded port): Direct hose connection, convenient for fixture retrofitting and standalone installations.
- K version (manifold mounting): Compact flush mounting onto hydraulic blocks, creating tidy concealed oil circuits for modular multi-station fixtures.
Modular Position Sensor Kit
Complete accessory package includes control cam and two sliding inductive proximity switches. The sensor housing can be rotated 180°, offering flexible layout adaptation for different fixture designs.
Robust Steel Housing & Reliable Sealing
Solid steel block construction withstands heavy clamping loads. Optimized sealing system minimizes internal leakage and extends service life under high-cycle production conditions.
