Easy-Access Mounted Sleeve Bearings

Lift the top off to install, inspect, and maintain your shaft without full disassembly. Inside, the sleeve is made from babbitt, a tough, corrosion-resistant alloy. With no moving parts, sleeve bearings stand up to dusty, dirty environments better than ball or roller bearings. However, with more friction generated, they're less effective at high speeds. The sturdy housing bolts down to support shafts as they turn.

Lubricate regularly through the housing's lubrication port to keep your bearing in tip-top shape. The grooves help to evenly distribute lubrication across the bearing's surface.

Powder-Coated Cast Iron Housing—A rugged iron base coated in thick powder that protects against water, mild detergents, and oil. However, if the coating is scratched or chipped, the underlying iron may rust.

Easy-Access Mounted Cylindrical-Roller Bearings

Thick, long rollers handle the highest loads of any mounted bearing we offer. Install them with confidence into coal crushers, sludge presses, wood hogs, and other demanding applications. The top lifts off for quick access when you need to install or maintain the shaft. The sturdy housing bolts down to support shafts as they turn.

Lubricate regularly to keep your bearing in tip-top shape, including upon installation. Seals hold lubricant in while keeping dust and contaminants out.

For Radial Loads—Accommodate minor changes in the length of your shaft as it expands and contracts from nearby machinery heat. They're typically positioned away from the drive end in assemblies with long shafts.

For Combined Radial and Thrust Loads—Secure shafts in place and absorb the thrust load. However, these bearings are not designed to handle shafts that expand or contract. They're typically positioned near the drive side of an assembly.

Clamp On—Tighten the clamping screw to close the collar around your shaft for a secure, mar-free grip. The collar centers the shaft, decreasing vibration and allowing for higher speeds than set screws. Also known as concentric lock bearings.

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 Metal-Reinforced Plastic Sleeve Bearings

Combine slippery plastic with the strength of metal. The PTFE core is naturally slippery, so you’ll never have to add lubricant. These bearings also keep your workspace clean with no lubricant to drip or flake and attract dust. Compared to all-metal bearings, they are lighter.

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.

Bronze-Backed PTFE with Steel Shell—A good all-around, economical choice. Although these bearings are stronger than aluminum, they can only be used in dry environments where corrosion is not a concern.

Easy-Install Dry-Running Flanged Sleeve Bearings

A gap running along the length of these bearings allows you to quickly squeeze them into a housing—no tools required. Made of naturally slippery plastic, there’s no need to add messy oil that could drip and attract dust.

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.

Nylon—The most popular choice, nylon is wear resistant yet economical. Keep in mind, though, that it will swell and weaken when exposed to moisture.

Shaft Grommets

Made of slippery plastic, these grommets allow shafts and bearings to spin freely in metal panels. The split construction lets you snap them around shafts you’ve already installed.

Nylon—Hard and durable, these grommets won't scratch or deform easily. They also withstand exposure to most mild chemicals, greases, fuels, and solvents.

MDS-Filled Nylon—These slippery grommets absorb friction from spinning shafts over long periods. However, they can’t withstand the same high temperatures as our other nylon grommets.
