MGPM25-75Z: Guided Thin Cylinder, High-Rigidity, Lateral Load-Resistant Unit with Slide Bearing Guide

Product Positioning
The MGPM25-75Z is a guided thin cylinder from SMC’s MGP-Z series, featuring a double-acting, single-rod design and slide bearings. This series integrates the drive cylinder with two parallel guide rods, effectively absorbing and resisting external lateral loads to protect the cylinder body while providing high-precision linear motion guidance. Its lightweight, compact design and excellent moment resistance make it an ideal actuator for automation scenarios such as material handling, workpiece pushing, lifting/stopping, and precision assembly.

Core Highlights: Lateral Load Resistance, Integrated Guide, Lightweight & Compact

• Integrated Guide Rod Design for Excellent Lateral Load Resistance
  The cylinder body integrates two high-rigidity internal guide rods, effectively isolating the impact of loads on the cylinder piston and seals, making it particularly suitable for applications with lateral impacts like workpiece stopping or blocking.
  The slide bearings, made of carbon steel alloy, provide excellent transverse stability and load capacity, protecting the cylinder from lateral impact damage.
• Lightweight & Compact Design for Energy Savings
  The MGP-Z series is an upgraded model, achieving up to 24% weight reduction compared to the original MGP series by shortening the guide rods and optimizing end plate thickness.
  Guide rods are shortened by up to 22mm, reducing the required clearance hole machining for cylinder installation and significantly saving installation space.
• Excellent Non-Rotational Accuracy
  Thanks to the precision guide structure, it effectively prevents piston rod rotation during motion, ensuring stable end effector posture.
• Rubber Bumpers for Smooth Stopping
  Utilizes rubber bumpers at both ends to effectively absorb impact energy at the end of the piston stroke, achieving smooth stopping and protecting the cylinder and load equipment.
• Built-in Magnet for Intelligent Control
  The cylinder body has a built-in magnet, allowing easy installation of a magnetic switch for non-contact detection and feedback of the piston position.
  Note: This model does not come standard with a magnetic switch; it must be ordered separately (e.g., M9B, A93 series).
• Flexible Mounting and Easy Piping
  Can be mounted from multiple directions and offers multiple piping port orientations, greatly enhancing layout flexibility in complex equipment.

Detailed Model Breakdown

Specifications Overview

Structure and Features
According to SMC technical data, key features of the MGP-Z series include:

• Integrated Guide Structure: Combines the cylinder body and guide mechanism into one for compact structure and high rigidity.
• Slide Bearings: Provide excellent transverse stability, specifically designed for applications with lateral impacts like stopping/blocking.
• Bearing Length Increases with Stroke: As the stroke increases, the length of the guide bearings also increases, thereby enhancing the cylinder’s load-carrying capacity.
• Direct Magnetic Switch Mounting: Round magnetic switches and magnetic field resistant switches can be mounted directly without an adapter plate.
• Space-Saving Design: Shortened guide rods reduce the amount of clearance hole machining required for cylinder installation.

Application Scenarios

• Workpiece Pushing & Transfer: Leveraging its high lateral load resistance to push or transfer workpieces stably.
• Lifting & Stopping: Used as a lift unit or stopper on conveyors, withstanding impact during workpiece stopping.
• Press-Fitting & Positioning: Ensures straight-line motion accuracy in press-fitting or positioning stations requiring precise guidance.
• Pick & Place: Used with end effectors like grippers for workpiece pick-and-place operations.
• Alternative to “Cylinder + External Guide Rail” Solution: Serves as an integrated solution in space-constrained applications requiring simplified design.

Summary: Self-Guided, High-Torque-Resistant Power Unit
The MGPM25-75Z guided thin cylinder perfectly solves the limitation of standard cylinders unable to withstand lateral loads, with its integrated guide rods and slide bearing design as the core advantage. Its lightweight and compact design significantly reduces system burden, the 245N (at 0.5MPa) thrust meets medium-load requirements, and rubber bumpers ensure smooth motion at stroke ends. Choosing the MGPM25-75Z means equipping your automation equipment with an integrated guided drive unit that offers high rigidity, excellent lateral load resistance, and smooth motion—an ideal choice for improving reliability and longevity in handling, pushing, and positioning processes.
