Linear Guides

Linear Guides, also known as Linear Rails, are a block and rail system that help aid the movement and support of a load or a piece of equipment in a linear fashion, either vertically or horizontally. A linear guide generally consists of a square section profile rail and a moving carriage. As the profile rail is square in section, both the ‘roll’ and ‘yaw’ of the payload is controlled.

In order to allow accurate and repeatable positioning of the payload, a linear guide uses recirculating ball bearings to support the carriage on the profile rail. This design also gives the advantages of very low friction and long bearing life. Linear guides can be used on their own or in pairs to support wider payloads. The payload is moved by a separate motor, often connected via a belt, leadscrew or ball screw.

For applications that require high accuracy and high-load capacity, a linear guide is an ideal solution. Linear guides are typically used in applications such as:

  • Industrial Automation
  • Industrial Robots
  • Machine Tool Equipment
  • Precision Measuring Equipment

Features and benefits Linear guides include:

  • Industry leading load capacities
  • High rigidity from back-to-back four roller track arrangement
  • Straight rails through advanced grinding technologies
  • Simple installation and greater accuracy with joint-free rails up to six meters
  • Smooth, quiet movement through patented insert moulded recirculation paths and optimised geometries
  • Multiple carriage styles and sizes available

Linear guides from Thomson Linear offer a complete assortment of rails and carriages that come in a broad range of styles, sizes and unique features, all produced to industry standard with dimensions for easy retrofitting into existing applications or designing into new applications.
