ROEMHELD Threaded Plunger Cylinder B1.464 Series

Product Overview

The ROEMHELD B1.464 is a single-acting, spring-return screw-in plunger hydraulic cylinder rated for a maximum operating pressure of 500 bar. It adopts a compact plunger structure without an extended piston rod, designed for fully embedded installation inside fixture plates, clamping bars and mold cavities.

Hydraulic oil is fed through internal drilled passages within the fixture body, requiring no external hydraulic port and enabling space-saving dense multi-point arrangement. Equipped with an integrated wiper seal, the cylinder blocks cutting fluid, metal chips and workshop contaminants from entering the internal spring chamber. The flat plunger face acts directly as the contact surface for supporting workpieces. Thanks to its ultra-short stroke and slim threaded body, it is widely used for anti-vibration backing and floating support in narrow fixture grooves.

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-Short 4 mm Stroke Plunger Design

The limited short travel avoids excessive workpiece displacement. It is ideal for rigid backing support to suppress chatter and deflection during milling, grinding and drilling of thin-walled components.

Slim Body for Installation Inside Clamping Bars

Compact threaded dimension allows direct embedding within standard clamping bars. It saves fixture space and simplifies the design of modular multi-station clamping systems.

Integrated Anti-Pollution Protection

Built-in wiper effectively isolates swarf and coolant. The sealed internal spring assembly reduces seal abrasion and leakage, delivering stable long-cycle performance under continuous CNC machining conditions.

Concealed Hydraulic Circuit Layout

Oil is routed via fixture internal drill holes. No exposed hoses eliminate collision risks with moving parts and create a neat, compact fixture structure.

Cost-Effective Single-Acting Circuit

Only one hydraulic supply channel is required. The built-in compression spring automatically retracts the plunger after pressure release, simplifying manifold configuration and lowering overall system investment.
