Description

MGP Series: Compact Guide Cylinder (Slide Bearing Type)

High-Rigidity Solution for High Lateral Load Applications

The MGP Series (Slide Bearing Type) is a compact, integrated guide cylinder designed for automation environments requiring superior resistance to side loads and high non-rotating accuracy. By combining a standard cylinder with two guide rods, this series provides a high-rigidity platform for lifting, pushing, and stopper applications.

Structural & Operational Features

Integrated Mounting & Piping: Supports four mounting styles (Top, Side, T-slot Side, and Bottom) and dual-direction piping (Top and Side ports) to maximize installation flexibility.
Slide Bearing Design: Uses lead bronze casting bushings and carbon steel guide rods to provide excellent stability under significant eccentric or side loads.
Compact Footprint: Ideal for space-constrained robotic arms and material handling systems.
Sensor Ready: Features integrated slots for auto switches on two sides for end-of-stroke detection.
Knock Pin Holes: Provided on each mounting surface to facilitate easy and repeatable positioning.

Ordering & Maintenance Notes

Intermediate Strokes: Available in 1mm and 5mm increments via spacers or specialized body types (-XB10).
Stopper Applications: When used as a stopper, only slide bearing types (MGPM) should be selected; strokes should be limited to 30mm or 50mm depending on bore size.
Filtration: Clean air filtered by a 40μm element is required to ensure long-term seal integrity
