-A Practical Selection and Application Guide for Automation

   In compact automation equipment, a pneumatic cylinder often has to do more than push or pull a load. The actuator may also need to resist lateral force, control rotation at the rod end, carry an eccentric load or maintain stable alignment during repeated cycles. A conventional compact cylinder may provide the required thrust but still need an external guide, anti-rotation mechanism or support rail.

 MGPM, MGPL and MGPA: Which Bearing Type Should You Choose?

    The series provides three bearing configurations for different operating priorities. The names and suitability described below are based on the product information supplied.

The MGPM series is a thin guide rod cylinder designed to combine pneumatic actuation and integrated guidance in one compact unit. It is also commonly described as a three-axis cylinder in some product literature. Its main purpose is not to create three independent motion axes. Rather, the term refers to a compact cylinder body working with two integrated guide rods to improve guidance and anti-rotation performance.

This guide explains the MGPM structure, the differences between the MGPM, MGPL and MGPA versions, the relationship between bore and stroke, and the questions engineers and purchasing teams should answer before specifying a model.

What Is an MGPM Thin Guide Rod Cylinder?

An MGPM cylinder integrates a pneumatic cylinder body with two guide rods. The cylinder supplies the linear driving force, while the guide rods constrain the output movement and help resist unwanted rotation and lateral deflection.

A guide rod cylinder does not make every load condition safe by default. It provides an integrated guiding function, but engineers must still check load direction, eccentric distance, moment, cycle frequency, impact, mounting rigidity and the manufacturer's allowable-load data.
