Linear guides and rail systems are machine elements that move heavy objects in a straight line with minimal friction or resistance. They typically have two main components: a stationary rail and a movable carriage, or slider, that supports the load and moves along the rail.

Linear Guides and Rail Systems
Category Selection
Linear guides and rail systems generate lower friction than comparable sliding bearings. Because of this, less power is required to move a load, higher speeds can be achieved, and greater efficiency is reached. Linear bearings and rails offer recirculating ball bearings to handle extremely heavy loads. External carriages and guides handle heavy loads in dirty environments, with constant lubrication. Internal carriages and guides handle lighter loads and tolerate component misalignment with no lubrication required.

Linear Bearings and Rails
Linear bearings and rail products provide 4-direction load sharing for lower friction and smooth motion. Linear bearing blocks are available in three different series, with flanged, rectangular, and long-rectangular form factors. Matching rails are precision ground for close-tolerance mating with the bearing blocks.

- 11 sizes available, with rail lengths up to 1000mm
- Normal preload
- Moderate precision class
- End seals included with all guides
- Made from stainless or carbon steel
- Rail hardness: HRC58-64
