Product Introduction of ROEMHELD B1.7384 RM Mini Slide
Product Overview
Two hydraulic connection options are available: side threaded port version for hose connection and O-ring sealed manifold mounting version for integrated tooling oil circuits. Position monitoring can be optionally configured via inductive proximity sensors or limit switches installed on either side of the housing. Standard sealing material is FKM, delivering excellent resistance to coolants and high temperatures. No built-in stroke end cushioning is provided.
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.

Integrated Multi-Guide-Rod Design
Four nitrided steel guide rods share radial loads and bending moments. Unlike standard block cylinders without external guides, this design avoids piston jamming and seal damage caused by offset clamping forces, extending service life significantly.
Compact All-In-One Slide Unit
Cylinder and guide structure are combined into a single block assembly. No extra separate guide housing is required, greatly reducing installation space compared to B1.738 series.
Built-In Front Tool Mounting Plate
Multiple threaded holes on the front plate enable direct installation of contact bolts, deburring tools, clamping jaws and auxiliary fixtures, simplifying fixture mechanical design.
Dual Hydraulic Connection Layouts
- B version (threaded side port): Suitable for independent installation with external hoses.
- F version (manifold mounting): Designed for concealed internal oil passages inside fixture base plates, eliminating exposed piping.
Flexible Position Feedback Configuration
Sensors can be mounted on the left or right side of the housing according to fixture layout. Signals confirm fully extended and fully retracted status for automated interlock control.
Safety Compliance & Maintenance-Free Guides
DIN EN 349 anti-crushing safety distance is implemented. The guide rod sliding interface is maintenance-free for long-term high-cycle operation.
