Product Introduction of ROEMHELD B1.4301 Threaded-Body Hydraulic Cylinder
Product Overview
The ROEMHELD B1.4301 is a single-acting, spring-return threaded-body cartridge cylinder, rated for a maximum operating pressure of 500 bar. It adopts compact short construction with an integrated piston spring and built-in rod wiper.
The cylinder features external male thread on the housing, which can be directly screwed into tapped holes of fixture bodies, clamping bars or manifold blocks. Hydraulic oil is supplied via internal drilled channels in the tooling, eliminating exposed hydraulic fittings and hoses. When hydraulic pressure is removed, the internal heavy-duty compression spring automatically retracts the piston. The spherical piston head provides reliable contact for clamping and supporting applications.
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.

Direct Screw-In Cartridge Installation
The threaded outer housing allows direct mounting into fixture tapped holes. Multiple cylinders can be arranged with minimal centre distances, ideal for dense multi-point clamping layouts. No extra mounting flange is required to save installation space.
Simplified Internal Hydraulic Oil Supply
Hydraulic fluid is delivered through drilled passages inside the fixture body. External pipe connections and hose fittings are omitted, reducing leakage risks and simplifying tooling surface layout.
Built-In Spring Return Design
Only one hydraulic supply port is required. After pressure relief, the integrated spring reliably retracts the piston, simplifying hydraulic circuit design and reducing valve quantity.
Spherical Piston Contact Head
The spherical piston surface enables slight angular compensation when contacting workpieces, avoiding piston jamming caused by minor alignment deviation.
Effective Anti-Contamination Performance
Built-in rod wiper prevents ingress of coolant, metal chips and machining debris, protecting internal sealing components in harsh CNC workshop environments.
