MGP Series Compact Guided Pneumatic Cylinder

The MGP Series Compact Guided Pneumatic Cylinder combines a double-acting pneumatic actuator with two integrated guide rods and a rigid front mounting plate.

Its compact structure provides controlled linear motion while helping resist piston-rod rotation and external side loads. Compared with a conventional cylinder and separately installed linear guide, the MGP integrates both functions into one compact unit, simplifying equipment design and reducing assembly space.

The series is available with bore sizes from 12 mm to 100 mm and with either slide bearings or ball-guide bearings. Standard stroke options extend up to 400 mm for selected bore sizes.

Key Features

Integrated Cylinder and Guide

The MGP combines a central pneumatic actuator with two parallel guide rods. This integrated design provides linear actuation and load guidance in one unit.

It can help reduce the need for:

Separate linear bearings

External anti-rotation devices

Custom guide brackets

Additional alignment components

Large installation frames

High-Rigidity Front Plate

The moving front plate connects the piston rod and both guide rods, providing a stable platform for attaching a fixture, tool or workpiece.

Ten Bore Sizes

Available bore sizes include:

12 mm

16 mm

20 mm

25 mm

32 mm

40 mm

50 mm

63 mm

80 mm

100 mm

The wide range allows the cylinder to be selected for compact positioning tasks as well as larger industrial loads.

Slide or Ball Guide Bearings

Two bearing types are available:

M: Slide-bearing type

L: Ball-guide-bearing type

The slide-bearing type is suitable for general industrial applications and environments where good rigidity and resistance to impact are important.

The ball-guide-bearing type provides lower rolling resistance and smoother motion, making it suitable for frequent operation and applications requiring low-friction movement.

Double-Acting Operation

Compressed air powers both extension and retraction, providing controlled force in two directions.

Integrated Non-Rotation Function

The two guide rods help maintain the angular orientation of the front plate throughout the stroke.

The catalog specifies non-rotation accuracy from ±0.10° to ±0.04°, depending on bore and bearing type.

Magnetic Piston Compatibility

The ordering guide identifies the MGP Series as supporting a magnetic piston for use with external auto switches.

Position detection can provide:

Extended-position confirmation

Retracted-position confirmation

PLC feedback

Machine-sequence control

Cycle counting

Safety interlocking

Fault detection

Compact Construction

The short overall length and integrated guide structure help reduce the space required inside machinery.

Rubber Cushioning

Rubber cushions reduce direct internal impact at the ends of the piston stroke.

Frequently Asked Questions

What is an MGP guided cylinder?

The MGP is a compact pneumatic cylinder with two integrated guide rods and a moving front plate. It combines linear actuation, load guidance and anti-rotation in one unit.

Is the MGP cylinder double acting?

Yes. The supplied specification identifies the MGP Series as double acting.

What bore sizes are available?

The available bores are 12, 16, 20, 25, 32, 40, 50, 63, 80 and 100 mm.

What is the difference between M and L?

M identifies the slide-bearing type. L identifies the ball-guide-bearing type.

What is the maximum operating pressure?

The maximum operating pressure is 1.0 MPa.

What is the minimum operating pressure?

The specified minimum operating pressure is 0.12 MPa.

What is the proof pressure?

The proof pressure is 1.5 MPa. It is a test rating rather than the normal operating pressure.

What is the operating-temperature range?

The specified ambient and working-medium temperature range is -10°C to +60°C.

What strokes are available?

Standard strokes depend on the bore. The supplied table lists strokes up to 250 mm for 12 and 16 mm bores and up to 400 mm for larger selected bores.

Why does the ordering guide show only 10–200 mm?

The ordering illustration shows a general 10–200 mm range, while the standard-stroke table lists longer strokes. Confirm any stroke above 200 mm before ordering.

Does the MGP have adjustable cushioning?

The supplied specification lists rubber cushions, not adjustable pneumatic cushions. External shock absorbers may be required for high-impact loads.

Can the MGP support a side load?

Yes, within its specified guide capacity. The exact allowable load and moment must be verified for the selected model and application.

Does the guided structure eliminate all rotation?

It provides high resistance to rotation, but a small angular tolerance remains. Refer to the non-rotation accuracy table.

What port sizes are used?

Depending on bore, the ports are M5 × 0.8, G1/8, G1/4 or G3/8.

Can magnetic switches be installed?

Yes. The cylinder supports magnetic piston sensing. Confirm the switch model and mounting requirements separately.

Can it operate with water, oil or another gas?

The specified working medium is compressed air. Other media require separate compatibility verification.
