ROEMHELD Threaded-Body Hydraulic Cylinder B1.470 Series
Product Overview
Equipped with a double wiper system and low-leakage sealing assembly, it effectively blocks coolant, metal chips and workshop contaminants. Dual O-ring & back-up ring sets provide reliable sealing between the cylinder outer thread and mounting bore. The hexagonal shoulder can be fully recessed into the fixture surface when tightened with a DIN 3116 pin face spanner for ultra-flat installation.
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.

Hydraulically Controlled Bidirectional Motion
Both advance and retraction rely on hydraulic pressure, eliminating dependence on mechanical return springs. It guarantees consistent cycle time, stable retraction speed, and can produce pulling forces for complex automated fixture sequences.
Double Wiper Anti-Contamination Construction
The dual wiper barrier greatly reduces ingress of cutting fluid and metal swarf. It minimizes seal wear and internal leakage, delivering long service life under continuous heavy CNC machining conditions.
Concealed Hose-Free Hydraulic Layout
Oil supply routed through drilled channels inside fixture plates. No exposed tubing eliminates collision risks with moving parts and supports dense multi-point clamping arrays.
Recessed Mounting Capability
The hexagonal shoulder can be sunk flush into the fixture surface. Compact embedded installation saves valuable space for narrow clamping bars and tight fixture cavities.
Flexible Clamping & Pulling Functions
Suitable for pushing clamping as well as pulling actuation. Widely used in automated tooling, welding fixtures and mold ejection where controlled retraction timing is mandatory.
