Sleeve Bearing Carriages for T-Slotted Framing

Mate with a T-slotted rail to add linear motion to your assembly. Carriages are suitable for washdown environments. Note: Carriages cannot be used upside down, vertically, or on their side.

T-slotted rails can be easily cut to length and drilled for mounting.

View additional T-slot hardware and accessories.

Hand brakes mount on the carriages to hold them in place on the rail. Carriages have mounting holes for the brakes.

End caps mount on the rails to prevent overtravel.

T-slot fasteners (sold separately) let you mount components to the carriages.

T-Slotted Framing Fasteners

Screw and nut sets or nuts secure brackets and other accessories to rails.

End-feed fasteners slide into the end of the rail to attach components. They form stronger connections than drop-in fasteners because more surface area touches the rail.

End-Feed Screw and Nut Sets

Single Nut with
Center Hole
and Button Head

Single Nut with
Offset Hole and
Flanged Button Head

Button head screws are more compact, so they're better for tight spaces than other screws for T-slotted framing.

Flanged button head screws have a wider head than standard button head fasteners, so you don’t need a washer for wide mounting holes.

Offset nuts have a mounting hole close to one end, so you can install them next to corners and rail ends.

T-Slotted Framing Linear Bearings and Track Rollers

Mount components to these load-rated bearings and track rollers to add linear motion along T-slotted rails.

Standard Sleeve Bearings for 2 Triple Rails

Bearings move more accurately than other T-slotted framing linear motion components, such as track rollers, and are often used in automated systems and other applications requiring repetitive motion. They’re lined with slippery, durable plastic and have no moving parts. These bearings withstand exposure to dirt, water, impact, and vibration. To adjust how they fit on your rail, slide one of the included shims between the bearing pad and bearing housing.

Standard sleeve bearings let you mount loads in multiple ways: using threaded holes on the panel and on the end of the mounting rail. The hole on the mounting rail end is often used to add bumpers.

Bearing pads replace worn pads.

Replacement carriage panels and mounting rails let you create custom standard sleeve bearings with different shapes and profiles.
