THK Linear Slides

Linear slides are transmission systems where roller elements act as the interface between a rail and a carriage, by rolling on bearing guideways arranged at 90° angles, in a linear motion. Linear slides are also known as liner guides or linear motion bearings and are ideal for any mechanical equipment that requires moving components in a straight line.

How do linear slides work?

Linear slides provide precise linear movement for medium to heavy loads. They are designed to have perfect rolling contact between the bearings and rail guideways. This helps to keep friction to the minimum and support heavy loads without compromising performance.

Linear guides often operate with no lubrication, offering self-lubrication with high performance. Their rigidity and stiffness translate to long term reliability even in high vibration and shock environments.

What are linear slides used for?

Linear guides are often used in modern machine tools, precision instrumentation and in the electronics industry. They are used in:

• Production packaging
• Food processing
• Automated test equipment
• Container manufacturing
• Material handling
• Component assembly
• Machine tool equipment
• Converting processes
• Medical equipment
• Laser measurement systems
• Sliding friction and wear tests
• Parts movement
