Linear guides are mechanical assemblies of linear rails and carriages designed to move and accurately position loads along a straight path. The Commercial Rail cam roller design features zinc-plated carbon steel linear rails with a U-shaped profile for corrosion resistance, standard mounting holes, and LaZer Straight™ bolt-on alignment for fast, accurate installation. Lightweight anodized aluminum carriages travel on preloaded, sealed roller bearings—lubricated for life and available in 52100 steel or 440 stainless steel—with integral wipers to keep contaminants out. An included open-end wrench allows quick preload adjustment in the field. Available in 20, 30, and 45mm rail widths with continuous rail lengths up to 6,000mm (236 in), these Commercial Rail linear guides combine high load capacity, excellent corrosion resistance, and reliable performance in harsh, dirty environments. The rails require a continuous layer of grease along their raceways, with fresh grease recommended every 50,000 cycles.

Frequently Asked Questions
What are linear guides used for?
Linear guides are mechanical assemblies that move and accurately position loads along a straight path. They are used in machinery, automation, material handling, and industrial motion systems.
How do cam roller linear guides work?
Cam roller linear guides use rolling bearings mounted on a carriage to travel along rail raceways, providing smooth, controlled linear movement and load positioning.
What is the difference between cam roller and ball bearing linear guides?
Cam roller linear guides use rolling bearings that travel along rail raceways, while ball bearing linear guides typically use recirculating balls between a rail and carriage. The designs differ in load handling, contamination tolerance, and maintenance requirements.
What materials are used in Commercial Rail linear guides?
Commercial Rail linear guides feature zinc-plated carbon steel rails, anodized aluminum carriages, and sealed roller bearings available in 52100 steel or 440 stainless steel.
What sizes are available for Commercial Rail linear guides?
Commercial Rail linear guides are available in 20mm, 30mm, and 45mm rail widths, with continuous rail lengths up to 6,000mm (236 inches).
Do cam roller linear guides require lubrication?
Yes. Although sealed roller bearings are lubricated for life, the rail raceways require a continuous layer of grease. Fresh grease is recommended approximately every 50,000 cycles.
Can cam roller linear guides operate in dirty environments?
Cam roller linear guides can operate in harsh or dirty environments. Commercial Rail features sealed roller bearings, integral carriage wipers, and zinc-plated rails to help resist contamination and corrosion.
How is bearing preload adjusted on Commercial Rail linear guides?
Bearing preload is adjusted using an open-end wrench to change the cam roller setting. Commercial Rail includes a wrench for field adjustments.
