Product Introduction of ROEMHELD Threaded-Body Universal Cylinder B1.309
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.

- Piston Rod Surface: Case-hardened precision ground rod with anti-wear tandem sealing assembly
- Minimum Spring Return Force (Single-Acting Version): 50 N ~ 430 N (varies by bore size)
Embedded Threaded Body for Space-Saving Layout
The full external thread outer shell allows direct screwing into fixture base plates, mold inserts and machine frame through holes. Lock nuts enable infinite fine axial adjustment of the cylinder position without extra adapter brackets, drastically reducing cabinet/fixture occupied space compared to flange-mounted cylindersROEMHELD.
Bottom-Only Hydraulic Connection Avoids Pipeline Interference
All oil ports are centralized at the cylinder rear end, eliminating pipeline collision with workpieces, clamping arms or mold moving parts during reciprocating strokes. It simplifies internal pipeline routing for multi-station compact fixtures and rotary tables matched with multi-port rotary unions.
Low-Leakage Tandem Rod Sealing System
The case-hardened piston rod is fitted with a dual tandem sealing set plus external dust wiper, minimizing internal leakage and blocking metal chips, coolant and workshop dust from invading the cylinder interior, extending service life under metal cutting and die-casting conditions.
Dual Drive Mode Flexibility
- Single-acting spring return: Hydraulic advance for clamping, mechanical spring retraction for release; ideal for low-cost simple clamping circuits with single oil supply port
- Double-acting: Independent hydraulic control for extend and retract strokes, applicable for high-frequency reciprocating positioning and heavy ejection tasks
Full Compatibility with ROEMHELD Hydraulic Ecosystem
Perfectly matched with ROEMHELD hydraulic power units, pressure boosters, rotary unions and position sensor accessories, forming complete high-pressure clamping systems for CNC machining, aluminum die-casting and automated assembly lines.
