Product Introduction of ROEMHELD Threaded-Body Hydraulic Cylinder B1.462

Product Overview

The ROEMHELD B1.462 is a single-acting, spring-return threaded hydraulic cylinder, rated for a maximum operating pressure of 500 bar. It evolves from the B1.461 platform and features a plunger-type piston structure without extended piston rod, also known as a plunger clamping cylinder.

The cylinder can be fully screwed into tapped holes of fixture plates until the hexagonal shoulder contacts the mounting surface. Hydraulic oil is supplied via internal drilled passages inside the fixture, requiring no external hydraulic port and supporting compact dense array arrangement. Equipped with a robust wiper and plunger barrier design, it effectively blocks cutting fluid, metal chips and contaminants from invading the internal spring chamber. The flat plunger top serves directly as the contact surface for supporting or clamping workpieces, eliminating the need for extra contact bolts and simplifying fixture layout.

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.

Integrated Plunger Contact Surface

Flat plunger top acts directly as clamping contact face. No separate contact bolt is required, reducing part count and assembly steps for compact fixture cavities.

Optimized Short-Stroke Structure

Limited short travel prevents excessive workpiece displacement. Perfect for workpiece support, anti-vibration backing and light clamping applications in milling and grinding processes.

Effective Anti-Contamination Construction

The plunger partition together with rod wiper isolates coolant and metal debris, protecting the internal spring and sealing components. It achieves low leakage and long service life under continuous CNC machining conditions.

Compact Embedded Screw-In Mounting

Fully recessed installation saves fixture space. Multiple cylinders can be arranged closely for multi-point synchronous supporting and clamping. Concealed internal oil passages avoid pipeline interference.

Simple Single-Acting Hydraulic Circuit

Only one hydraulic supply channel is needed. Built-in compression spring automatically retracts the plunger after pressure release, simplifying manifold design and lowering system costs.
