Corrosion-Resistant Maintenance-Free Ball Bearing Carriages and Guide Rails

Mounting hole plugs protect mounting fasteners from corrosion.
Self-Aligning Sleeve Bearing Carriages and Guide Rails


A floating bearing in these self-aligning carriages adjusts to compensate for misalignment between rails, so your carriages still move in tandem. For a complete system, you’ll need a self-aligning carriage and rail on one side and a fixed-alignment carriage and rail on the other (all sold separately).
Carriages for axial rail misalignment compensate when the rails aren’t installed at the same exact height.
Carriages for parallel rail misalignment compensate when one rail is straight and the other is installed at a slight angle.
Note: Each carriage can only be used with its corresponding guide rail. Load capacity is diminished when carriages are mounted upside down or on a vertical surface.

Locking Sleeve Bearing Carriages and Guide Rails



A handle on the side of the carriage locks the carriage in place. With fewer moving parts and no need for lubrication, sleeve bearing carriages perform better in dusty and wet environments than ball and roller bearing carriages. They're also better at handling impact and vibration.
Note: Load capacity is diminished when carriages are mounted upside down or on a vertical surface.

Self-Aligning Locking Sleeve Bearing Carriages and Guide Rails
Create a self-aligning system that can be locked in place with these carriages and guide rails. The floating bearing in these self-aligning carriages compensates for misalignment, so carriages will still move in tandem even if the rails aren’t installed at the same exact height. A complete system includes a self-aligning carriage and rail on one side and a fixed-alignment carriage and rail on the other (all sold separately).

Side-Mount Track Roller Carriages and Guide Rails



Mount along a wall or other vertical surface.
Carriages with adjustable rollers can be adjusted for a snug or loose fit on the rail (also known as preload).
Carriages with wipers sweep away dust and other contaminants.

T-Slotted Framing Rails
Use this versatile framing to configure machine guards, enclosures, carts, and workstations. These rails have continuous T-slots for attaching fittings. When choosing how many slots you want on your rail, consider how much flexibility you need for your setup and how finished you'd like your structure to appear. The more slots the rail has, the more design flexibility you will have. Keep in mind, open slots can collect dust and debris. Rails with closed sides give you a finished appearance but are more difficult to reconfigure or add components to later. All of these rails are made of aluminum.
Double-, triple-, and quad-profile rails are good for large structural applications, such as beams and posts. Typically, the larger the rail profile, the stronger the rail.
Hollow rails are lighter and more economical than solid rails.
Smooth rails give a finished look. With no indentations to collect dust, they’re easier to clean than grooved rails. However, dents and marks are easier to see.
Black rails fade into the background and hide dirt and grime. They're good for vision systems where non-reflective material is needed. Yellow rails draw attention and are often used to build machine guards.
Cut-to-length rails can be ordered in increments of 0.125” or 0.25 cm.
