Linear Guides - Rails

A linear guide rail is a fixed beam cut to length, along which any number of items can move freely, depending on the load needed and the configuration of the fixture. Linear guide rails are typically used on doors, machine guarding and seating. 


Types of linear guides


Guides with plain motion 

Plain bearings are the simplest type of linear guides, with their straightforward construction and easy installation process. There are several types, including boxway and dovetail, both of which can carry high loads. 


Guides with rolling motion

Rolling linear guides incorporate balls or rollers between two bearing surfaces. They can be recirculating or non-recirculating: recirculating designs have ongoing motion along the rail and so can continue to roll for an infinite distance, while non-recirculating designs are limited by the length of the bearing. 


Types of rails

There are various different types of linear rails, ranging from 'V'-shaped steel rails through to compact shaft raceways and flexible options made from stainless steel and aluminium.
