Product Introduction of ROEMHELD Universal Cylinder B1.311 Series
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.
- Operation Type: Double-acting hydraulic (independent extend & retract control)
- Max Rated Operating Pressure: 400 bar
- Standard Piston Bore Sizes: 25 / 32 / 40 / 50 / 63 mm
- Standard Stroke Options: 32 mm / 40 mm / 64 mm
- Standard Sealing Kit: NBR (-20 °C ~ +80 °C); optional FKM/Viton high-temperature sealing upgrade (-20 °C ~ +120 °C)
- Hydraulic Port Thread: G1/4
- Piston Rod End: Internal metric thread for clamping head connection
- Mounting Method: Inserted into smooth through hole, fixed by circlip at different axial positions
Embedded Circlip Mounting with Adjustable Position
The cylinder body can be directly inserted into unthreaded smooth through holes. Circlips allow continuous axial position adjustment without extra lock nuts or adapter plates, saving fixture space and simplifying installation for multi-station compact clamping systems.
Dual Port Arrangement (Radial + Axial)
Hydraulic oil ports can be connected radially or axially. Designers can flexibly select piping directions to avoid pipeline interference in dense fixture cavities.
Stable Bidirectional Force Output
Double-acting structure delivers controllable thrust and pull force. Unlike single-acting spring return cylinders, retraction speed and force are fully hydraulically regulated, ideal for high-frequency reciprocating ejection, positioning and pressing operations.
Enhanced Contamination Protection
Built-in external wiper prevents ingress of cutting fluid, fine metal swarf and dust. Combined with high-performance sealing system, it minimizes internal leakage and improves durability under harsh CNC machining conditions.
Compatibility with ROEMHELD Hydraulic Ecosystem
Seamlessly matched with ROEMHELD hydraulic power units, pressure boosters, multi-port rotary unions and position sensor accessories to form complete hydraulic clamping solutions for rotary tables and flexible machining fixtures.
