What materials are compact hydraulic cylinders made from?

Compact hydraulic cylinders are made from a high-strength special aluminium alloy with a wear-resistant surface treatment (RP/MP), or from steel (RQ), which ensures service life and reliability even in demanding operating conditions.

Are compact hydraulic cylinders available with custom strokes?

Compact cylinders are held in stock with fixed strokes of 20, 50, 80 and 100 mm. Custom strokes can be supplied to the customer's requirements thanks to fast production of special parts.

Can I download 3D CAD models of compact cylinders?

The online configurator guides you step by step through selecting the most suitable cylinder and validates the required configuration. You can download complete 2D and 3D models of compact cylinders, including all technical documentation, for immediate integration into your projects.

Can compact hydraulic cylinders be fitted with magnetic sensors?

Yes. The aluminium compact cylinders of the MP series are designed for the integration of magnetic sensors. The sensors allow monitoring of the piston end positions and optimisation of working cycles. Reed sensors with an M8 connector are available, and special IO-LINK solutions on request.

Which types of seal are used in compact double-acting cylinders?

Various configurations are available depending on the application: high sealing (S, RP/MP only), low friction (L), high temperature (H, Viton) and HFC-fluid compatible (G). The RQ series does not use the S seal.

Which accessories and configuration options are available for compact cylinders?

The oil ports can be threaded or O-ring type, in several positions (front, rear and side). The standard rod end has a female thread, compatible with a male-threaded end or a floating joint. Further modifications are possible on request.

What is the difference between the RP, MP and RQ series?

RP is a compact double-acting cylinder made of high-strength aluminium alloy for pressures up to 160 bar and light to medium loads. MP is the aluminium variant with an integrated position sensor for end-position detection. RQ is the steel version for pressures up to 250 bar across the whole Ø 25–100 mm range — it withstands shock and cyclic loads and offers a longer service life. Choose RP/MP up to 160 bar, and RQ for higher pressures and harsher duty.

RP / MP / RQ Compact Hydraulic Cylinders

Q: Which applications are compact double-acting hydraulic cylinders suited to?

Compact cylinders are used across many fields of industrial automation, including moulds and injection moulding machines, clamping systems and special-purpose equipment, where space is limited and high push and pull forces are required.

Double-acting cylinders for industrial automation

Compact double-acting hydraulic cylinders RP, MP and RQ in high-strength aluminium alloy or steel. Operating pressure 160 bar (RP / MP, 100 bar for Ø 80–100 mm) or 250 bar (RQ, steel), bore diameter Ø 25–100 mm. Catalogue strokes of 20, 50, 80 and 100 mm from stock, custom strokes on request.

The aluminium MP version allows the integration of Reed or IO-LINK magnetic sensors for monitoring the piston end positions — so the compact envelope also carries feedback to the control system.

Configurator

Select your cylinder’s parameters

Set the series, mounting, bore and stroke directly in the manufacturer’s CodeWizard. It builds the exact cylinder, generates the configuration code (SKU) and a technical datasheet, lets you download the CAD model, and sends your request for quotation straight to us — no separate inquiry form needed.

Three series · One envelope

Compact, high-pressure, or tie-rod cylinder?

RP, MP and RQ share a compact installed length and bores of Ø 25–100 mm. The steel RQ offers a higher pressure of 250 bar and shock resistance, while MP is the aluminium version with magnetic position sensors. For larger bores and any stroke, the tie-rod CD / DK cylinders to ISO 6020/2 are the answer.

Industrial applications

Where the cylinders are used in industry

Applications with limited installation space that still need high push and pull forces — moulds and injection moulding machines, clamping systems, chucks and special-purpose machines.

High force in a minimal installed length.

RP: Clamping and holding in moulds, fixtures and special-purpose machines — aluminium body, low weight, strokes of 20–100 mm.
MP: Automated cycles with feedback — SP magnetic sensors watch the piston end positions and govern the sequence of steps.
RQ: The steel version up to 250 bar for shock and cyclic loads — CNC clamping, chucks, injection moulding machines and pressing fixtures.
