Linear Guides
Linear guides constrain moving elements to a precise straight-line path, providing the support and load-bearing guidance needed for controlled positioning in industrial machinery. A linear guide rail and carriage assembly is typically paired with a drive component, such as a ball screw or servo motor, to form a complete motion axis. PLC Direct supplies Rexroth linear guides as an independent supplier to maintenance and procurement teams sourcing replacement parts for existing installations.
Where Are Linear Guides Used in Industrial Environments?
Linear guides are used wherever a moving element must be supported and guided along a straight path with low friction and consistent load-bearing capacity. They form the structural guidance layer of machine axes in CNC equipment, semiconductor systems, packaging automation, and precision industrial machinery across multiple sectors.
Facilities and operations that depend on linear guides include:
-
CNC machining centers and grinding machines for guided axis travel across X, Y, and Z axes.
-
Semiconductor and flat panel display equipment for precision stage and gantry positioning.
-
Packaging and filling machinery for carriage and head positioning along production lines.
-
Pick-and-place automation and industrial robots for guided arm and gantry travel.
-
Laser cutting and engraving machines where straight, low-friction carriage travel directly affects cut quality.
In any application where a linear guide rail develops wear, misalignment, or damage, replacing the affected component to the original specification restores guidance accuracy and prevents secondary wear to mating parts.
Which Brands of Linear Guides Does PLC Direct Stock?
PLC Direct stocks linear guides from Rexroth for replacement and maintenance in existing installed systems.

Rexroth Linear Guide Rail Systems: Rexroth manufactures profiled linear guide rail and carriage assemblies for precision guidance in CNC machine tools, semiconductor, packaging, and industrial automation applications.
All Rexroth linear guide hardware is available as surplus sealed, refurbished, and used.
What Should You Know Before Ordering Linear Guides?
Hardware condition options: Linear guides are available as surplus sealed, refurbished, and used. Surplus sealed units are factory-sealed stock; refurbished units have been inspected and restored to operational condition. Used units are tested as functional. For precision axes, condition grade and preload class should be matched to the machine's guidance accuracy and load requirements before ordering.
Compatibility and part identification: Linear guide rail and carriage part numbers encode series designation, size, accuracy grade, preload class, and carriage type within the number. Rails and carriages within the same series are typically compatible, but size, accuracy grade, and preload class must all match the installed components. Rail length is also a specification variable; confirm the installed rail length from machine documentation before ordering a replacement rail section.
Warranty: All linear guide hardware purchased from PLC Direct carries a standard 1-year warranty covering defects and functionality, applicable to surplus sealed, refurbished, and used products.
PLC Direct supplies linear guide hardware for replacement and maintenance purposes and does not provide system design, programming, or integration services.
