Linear bearings and rails use continuously circulating ball bearings to support static loads from 2650N to 74600N, equalizing and sharing directional loads for lower friction and smooth motion. Compact blocks offer two rows of bearings; certain models offer four rows for maximum load capacity.

Linear Guides and Rail Systems
Category Selection
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 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.
- Load ratings up to 74,600N (16,770lbf)
- 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
Internal Carriages & Guides
LU series internal carriages ride inside guide tracks. Choose from three carriage sizes (each has two wheel shapes) with matching guide rails up to 1520mm in length.
- Load ratings up to 169N (38lbf)
- Crowned and double-v shaped wheel versions are designed to be used in tandem for forgiveness with misaligned components
- Guide rails can be mounted end-to-end for longer travel lengths
- No lubrication required
External Carriages & Guides
LV series external carriages ride outside guide tracks. Choose from three carriage sizes with matching guide rails up to 1256mm in length.
- Load ratings up to 4,700N (1,057lbf)
- V-shaped wheels push debris away as they rotate
- Guide rails can be mounted end-to-end for longer travel lengths
- Wheel covers provide constant lubrication
Guide Tracks with Slides
Ceramic coated aluminum guide tracks support anodized aluminum slides bonded with FrelonGOLD®, a proprietary, self-lubricating, PTFE coating to support loads even in extreme temperatures. They offer smooth, quiet operation with vibration damping and shock resistance.
- Load ratings up to 8,200 N (1,843 lbf)
- Seven track sizes with available lengths up to 2000mm
- Operating temperature range from -400°F to 400°F (-240°C to 204°C)
- No additional lubrication required
Linear Guides & Rail System Accessories
Accessories include the required tensioning tools for internal and external guide rail carriages as well as mounting clamps for guide tracks.
- LUACC-x for use with LU carriages
- LVCACC-x for use with LVC carriages
