Dry-Running Thrust Bearings

Made of naturally slippery plastic so there's no lubricant to maintain or make a mess. These bearings are ideal for spic-and-span spaces since oil won't drip off, wash out, or collect dust over time. They'll also never rust.

Moisture-Resistant Plastic Blend—Similar to acetal, these bearings won't warp or swell from water or humidity.

Dry-Running Flanged Sleeve Bearings

Made of naturally slippery plastic so you’ll never have to add lubricant. They’re ideal for clean environments where you need to prevent oil drips or graphite flakes. Compared to metal bearings, they are lighter and will never rust.

Flanged sleeve bearings combine a sleeve and thrust bearing in one. The flange supports thrust loads and prevents the bearing from being pushed out of place. The sleeve is the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.

Moisture-Resistant Acetal—These bearings won’t warp or swell from humidity or direct contact with water, unlike nylon.

Moisture-Resistant Ultra-Low-Friction Plastic Blend—These bearings won't warp or swell from humidity or direct contact with water. They glide effortlessly for applications with frequent starts and stops, such as conveyor systems.

Dry-Running Panel-Mount Sleeve Bearings

Leave the lubricant in the supply closet—these low-maintenance sleeve bearings are made from naturally slippery plastic. They'll keep shafts spinning with no messy grease to drip off, wash out, or collect dust. With no moving parts, sleeve bearings withstand grimy environments better than ball bearings. However, with more friction generated, they're less effective at high speeds. They mount securely in thin panels.

Acetal—The most common choice for plastic bearings, acetal is wear-resistant and affordable.

Ultra-Low-Friction PTFE-Filled Acetal—Made from a special blend of acetal and PTFE, these extra-slippery bearings are ideal for conveyors and other machinery with frequent starts and stops.

Steel Housing—Best for dry environments as moisture will cause them to rust.

Press-Fit Panel Mount—Press these bearings into plastic panels or thin sheet metal to mount them by hand. They're a good fit for tight spaces, or if you'd like a removable mounting option. The sturdy flange prevents bearings from pulling through, giving you added stability.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.

Dry-Running Sleeve Bearings

With no moving parts, sleeve bearings are the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.

Recycled Plastic Blend—A sustainable alternative to new plastic. These bearings handle higher loads and a wider temperature range than nylon.
