Product Introduction of ROEMHELD Universal Clamping Cylinder B1.310
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.

Flexible 10 mm Step Axial Position Adjustment
The core competitive feature of B1.310: stacked spacer rings allow continuous fine adjustment of the cylinder’s overall extension length in 10 mm steps. It solves the pain point of frequent fixture rework for multi-size workpiece families, avoiding repeated re-machining of fixture base plates and greatly shortening tooling changeover time for mixed production lines.
Dual Installation Solutions for Compact Fixtures
Two mainstream mounting forms are supported:
- Direct embedded mounting: Threaded cylinder body inserted into fixture wall through holes, fixed by circlip;
- External bracket mounting: Matched with horizontal/vertical standard brackets for surface installation on thin fixture plates.
Both forms save cabinet layout space compared to conventional flange cylinders.
Optimized Single-Acting Spring Return Structure
Built-in high-precision compression spring delivers stable retraction force after hydraulic pressure release, ensuring reliable automatic workpiece release without reverse hydraulic oil supply. Only one oil port is required for the hydraulic circuit, reducing valve block and pipeline costs for simple clamping stations.
Convenient Air Bleeding & Stable Clamping Performance
Air inside the cylinder can be fully discharged via the G1/4 port joint; model 1316 adds an independent bleed screw for rapid venting during commissioning. Fully drained internal air eliminates clamping force fluctuation and piston jitter during mass production.
Full Compatibility with ROEMHELD Hydraulic Ecosystem
Seamlessly matched with ROEMHELD hydraulic power units, pressure boosters, rotary unions and magnetic position sensors, forming a complete flexible clamping system for multi-station CNC machining centers and automated assembly lines.
