ROEMHELD Threaded Hydraulic Cylinder B1.450 Series
Product Overview
The B1.450 series is a single-acting, spring-return threaded hydraulic cylinder developed by ROEMHELD, designed for fully embedded installation in fixture plates, mold structures and compact machine housings. With a high maximum operating pressure of 500 bar, this compact cylinder delivers stable and powerful clamping force for heavy-duty workholding, positioning and ejection tasks in precision machining and automation systems.
Featuring a full external threaded body, the B1.450 can be directly screwed into unthreaded mounting holes and fixed with lock nuts, achieving space-saving installation without additional brackets. The built-in spring provides reliable automatic retraction after pressure release. Equipped with an integrated rod wiper and high-performance sealing system, it offers excellent resistance against coolant, metal chips and workshop contamination, ensuring long service life under harsh CNC machining conditions.
Q: What’s the MOQ of customized tie-rod cylinder?
A: Depends on the style of tie-rod. We would like to cast and forge once the quantity above 100 pcs.
Q:What’s the lead time of customized tie-rod cylinder?
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.
Q: Are you the manufacturer of hydrualic cylinder?
A: Sure, we are the manufacutuer and trading of hydraulic cylinder.
Q: What is the difference between double acting and single acting cylinders?own controlled by the pump or the valve or is it only one speed?
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.
Q: I have a drawing, could you customized cylinder as my drawing?
A: Sure. Show us the drawing, we will quote for you soonest.
Q: Could you make the cylinder which is not on the above data sheet?
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.

Ultra-Compact Embedded Threaded Structure
The full external thread design enables direct installation inside fixture and mold plates. It eliminates bulky mounting flanges and adapters, greatly optimizing space layout for dense multi-station fixtures and compact automated tooling.
High 500 Bar Heavy-Duty Clamping Performance
Rated at 500 bar ultra-high pressure, the B1.450 provides large clamping force with a tiny body size. It replaces larger conventional cylinders, effectively reducing overall fixture volume while maintaining stable and rigid clamping for metal cutting and forming processes.
Reliable Spring Return Mechanism
Precision built-in compression spring ensures fast, consistent and fully automatic retraction once hydraulic pressure is released. The single-acting structure simplifies hydraulic circuits with only one oil supply port required, lowering valve and piping costs.
Excellent Harsh Environment Adaptability
Equipped with standard dust wiper and low-leakage sealing assembly, the cylinder resists coolant erosion and fine metal chip pollution in long-cycle CNC workshop environments. Optional FKM seals support high-temperature and chemical-demanding working conditions.
Clean Internal Piping Layout
The rear centralized oil port design avoids exposed pipelines and interference with moving parts, ensuring neat internal routing inside molds and fixture cavities and improving overall equipment safety and stability.
