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 & Rail Systems
Linear guides and rail systems generate lower friction than comparable plain 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. Guide tracks with slides use a PTFE bonded coating on the slide to handle heavy loads, even in extreme temperatures, with no additional lubrication required.

Linear Bearings & 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.
- High load capacity up to 74,600 N (16,770 lbf) supports demanding industrial motion applications
- Broad offering with 11 sizes and rail lengths up to 1000 mm simplifies sizing across machine designs
- Normal preload and moderate precision class balance smooth travel, rigidity, and cost-effectiveness
- End seals standard on all guides help reduce contamination and extend service life
- Choice of stainless or carbon steel to match corrosion resistance and strength requirements
- Hardened rails (HRC 58–64) deliver long wear life under continuous motion
Internal Carriages & Guides
Internal carriages and guides are compact motion components designed for light-duty, guided travel within enclosed tracks. The LU series offers multiple carriage sizes and wheel profiles with matched guide rails to support smooth, forgiving motion in space‑constrained designs.
- Load capacity up to 169 N (38 lbf) for lightweight positioning and guiding applications
- Three carriage sizes with two wheel geometries provide flexibility across a wide range of layouts
- Crowned and double‑V wheel options work together to accommodate minor misalignment and improve tracking
- Internal guide track design protects rolling elements from debris and accidental contact
- Guide rails available up to 1520 mm, with end‑to‑end mounting for extended travel
- Maintenance‑free operation eliminates the need for lubrication
- Well‑suited for cost‑sensitive automation, guarding, and light transport systems
External Carriages & Guides
External carriages and guides deliver robust, guided motion for applications where strength and contamination resistance matter. The LV series features externally mounted carriages paired with precision guide rails, offering dependable performance for higher‑load, open‑track designs.
- Load capacity up to 4,700 N (1,057 lbf) supports heavier loads than typical light‑duty guide systems
- Three carriage sizes provide scalable options across a range of machine requirements
- V‑shaped wheels actively shed debris during travel, helping maintain smooth operation in dirty environments
- Guide rails available up to 1256 mm, with end‑to‑end mounting for extended travel lengths
- Integrated wheel covers deliver continuous lubrication, reducing maintenance effort
- External running surfaces allow for easy inspection and access
Guide Tracks with Slides
Guide tracks with slides combine lightweight construction and advanced materials to deliver smooth, quiet motion in demanding environments. Ceramic‑coated aluminum tracks paired with FrelonGOLD®‑bonded slides provide reliable load support across extreme temperatures without added maintenance.
- Load capacity up to 8,200 N (1,843 lbf) supports moderate to heavy linear loads
- Seven track sizes with lengths up to 2000 mm cover a wide range of machine designs
- Ceramic‑coated aluminum tracks improve wear resistance while keeping system weight low
- Slides bonded with FrelonGOLD® self‑lubricating PTFE enable smooth travel without external lubrication
- Wide operating temperature range from ‑400°F to 400°F (‑240°C to 204°C) suits extreme environments
- Quiet operation with vibration damping helps protect sensitive equipment
- Shock‑resistant construction enhances durability under dynamic loading
