MR Mini-Rail Miniature Linear Slide | Self- Lubricating

MR Mini-Rail Miniature Linear Slide

Based on self-lubricating Simplicity technology, the Mini-Rail linear slide’s effective two-piece design allows for fast installation and provides outstanding performance in demanding linear motion applications from semi-conductor wafer handling to packaging equipment. With no rolling elements, the Mini-Rail will not catastrophically fail. The Mini-Rail also features our proprietary FrelonGOLD® liner, which ensures oil-free operation throughout the lifespan of the linear slide system due to its self-lubricating properties. The Mini-Rail is a fully interchangeable and economical solution to industry standard linear slides and profile rails. In addition to being offered in several widths, the Mini-Rail linear slide comes in a variety of off-the-shelf and custom lengths up to 3,600 mm.

Precision & Compensated Clearances for Uni-Guide

Carriage Configuration Options

Running Clearance

Precision Series: Ceramic-coated rails and carriages offer superior corrosion resistance. The FrelonGOLD self-lubricating liner ensures optimal performance, supporting the highest loads, best wear life, and fastest speeds. Designed with the most precise running clearance for high-precision applications.

Compensated Series: Similar to the Precision Series but with additional clearance to accommodate misalignment.


Use the product configurator to determine the ideal running clearance for your linear motion application.


Design Considerations for UGA

Cantilevered Loads

The carriage will bind if the 2:1 ratio for cantilevered loads and drive forces is exceeded. This principle does not depend on load or force. The 2:1 Bearing Ratio defines the maximum allowable ratio of moment arm distance to bearing length that prevents binding or motion hindrance. It is often represented numerically as "2:1," where "2x" is the moment arm distance and "1x" is the bearing length. For example, if 2x equals 10 inches, then 1x must equal 5 inches.
