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 are corrosion resistant. FrelonGOLD self-lubricating liner delivers the best overall performance, the highest loads, the best wear life, and speeds. Most precise running clearance for high precision applications. 

Compensated Series: Same as Precision Series except with additional clearance provided to tolerate misalignment. 

Use the product configurator to specify the optimal running clearance for your linear motion application.

Design Considerations for Mini-Rail

Cantilevered Loads

The carriage will bind if the 2:1 ratio for cantilevered loads and drive forces is exceeded. This principle is independent of load or force. The 2:1 Bearing Ratio is defined as the maximum allowable ratio of moment arm distance to bearing length that avoids binding or motion hindrance. Numerically, it is represented as "2:1," where "2x" is the moment arm distance and "1x" is the bearing length. For example, if 2x is 10 inches, then 1x must be 5 inches.
