About Plain Bearings

Food Industry Oil-Embedded Flanged Sleeve Bearings
The oil in these bearings is suitable for incidental contact with food. Startup friction produces a thin layer of oil on the bearing’s surface. All are FDA Compliant or NSF Registered, so they're safe for use in food applications.
UHMW bearings resist chemicals better than 841 bronze bearings, and they retain oil better in wet environments. They also withstand caustic and washdown environments.
Note: Dynamic load capacity is the maximum load a bearing can withstand at a given shaft speed. If your application’s load and speed requirements are below the values listed, the bearing will work.

Wheel Reducer Bushings
Reduce the inside diameter of a bearing to fit a particular axle size. Also known as spanner bushings, they also reduce wear on the axle when used in plain bores and with straight roller bearings. All have a hole for lubrication.
Washers slide over the bushing and add 3/32" to the hub length of your wheel. Multiple washers can be used to match the length of the bushing.

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.
For technical drawings and 3-D models, click on a part number.
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.
Flanged sleeve bearings mount in two different orientations: one where the bearing slides along the rail and another where the bearing acts as a mount allowing the rail to slide. Fasten bolts through the flange holes to secure them to rails, loads, and other surfaces.
Bearing pads replace worn pads.

Hand brakes hold sleeve bearing carriages in place on the rail. Single arm brakes have an adjustable grip. If space is tight, you can ratchet the grip out of the way without releasing the brake.

Track rollers are for applications that don't require high precision, such as sliding door frames, glides, and track systems. Multiple track rollers can be used on a rail. Because they’re side mount, they allow you to attach and roll components along the side of the rail.
Sleeve bearings don’t need to be lubricated, but they aren’t as long-lasting and don’t roll as smoothly as ball bearings.
