Ball Bearings

These steel ball bearings handle higher loads than stainless steel and plastic bearings.

Permanently Lubricated Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Because it's solid, the lubricant blocks out water and dust, extending the life of the bearing.

Set Screw Collar Ball Bearings

Slip these bearings onto a shaft and secure with the included set screws, no special tools required.

Washdown Set Screw Collar Ball Bearings

Secure these bearings in washdown areas, such as food, beverage, pharmaceutical, and chemical plants, by tightening the set screw onto a shaft—no additional collar needed.

One-Piece Thrust Ball Bearings

In addition to handling higher loads than three-piece ball bearings, one-piece bearings are easier to handle. They have an outer band that holds the bearing together and acts as a shield against dust and other contaminants.

Roller Bearings

Tapered-Roller Bearings

Found anywhere from machine tool spindles to conveyor rollers, these bearings have a two-piece design that allows for adjustment.

Needle-Roller Bearings

Also known as drawn-cup roller bearings, these are our thinnest roller bearings. The outer ring is drawn out to form a lip that holds the bearing together.

Precision Needle-Roller Bearings

These bearings have higher radial load capacity, speed, and accuracy than standard needle-roller bearings.

Needle-Roller Thrust Bearings

Thinner rollers allow these bearings to fit in tighter spaces than tapered-roller thrust bearings.

Washers for Needle-Roller Thrust Bearings

Adapt needle-roller thrust bearings to use on unhardened, unground surfaces.

Tapered-Roller Thrust Bearings

Thick, tapered rollers stand up to extremely high thrust loads.

Plain Bearings

Oil-Embedded Sleeve Bearings

Also known as Oilite® bearings.

High-Load Oil-Embedded Sleeve Bearings

Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds.

High-Temperature Dry-Running Sleeve Bearings

Graphite provides a layer of dry lubrication that can operate in high-temperature environments.

Multipurpose Sleeve Bearings

These bronze bearings are strong, wear resistant, and excellent at handling shock loads.

Oil-Embedded Flanged Sleeve Bearings

Also known as Oilite® bearings.

High-Load Oil-Embedded Flanged Sleeve Bearings

Increased iron content makes these bearings stronger and more resistant to shock loads than standard oil-embedded bearings; however they operate at lower speeds.

Multipurpose Dry-Running Flanged Sleeve Bearings

Reinforced with polyester fabric, these plastic bearings have load and speed capabilities comparable to metal bearings.

Multipurpose Flanged Sleeve Bearings

These bronze bearings are strong, wear resistant, and excellent at handling shock loads.

Corrosion-Resistant Flanged Sleeve Bearings

The addition of iron and aluminum gives these aluminum-bronze bearings high strength and excellent corrosion resistance—making them suitable for use in marine and mining applications.

Oil-Embedded Thrust Bearings

Also known as Oilite® bearings.

Ultra-Low-Friction Oil-Embedded Thrust Bearings

For applications with frequent starts and stops, the oil in these bearings contains particles of slippery PTFE that lubricate the bearing during startup.

High-Load Dry-Running Thrust Bearings

A metal backing adds strength.

Mounted Bearings

Mounted Ball Bearings

Ball bearings operate with less friction than other bearings, so they can run at higher speeds.

Low-Profile Mounted Ball Bearings

Designed with a thin, compact housing, these bearings are good for space-constrained applications.

High-Speed Mounted Ball Bearings

These bearings have the highest speed ratings of any mounted ball bearing that we offer.

Washdown Mounted Ball Bearings

Meeting IP69K for washdown environments, these mounted ball bearings are used in food, beverage, pharmaceutical, and chemical plants.

Extra-Clearance Mounted Ball Bearings

Keep shafts, such as those with a shoulder, clear of the mounting surface. These bearings have a higher mounting base that gives them more space to the mounting surface than standard mounting bases.

High-Speed Oil-Embedded
Mounted Sleeve Bearings

A strong steel housing allows these bearings to handle higher speeds than standard oil-embedded mounted sleeve bearings.

Mounted Roller Bearings

Roller bearings have a thinner profile and larger contact area than ball bearings, making them stronger and more space-efficient than ball bearings.

Mounted Ball Bearings with Two-Bolt Flange

Ball bearings operate with less friction than other bearings, so you can run them at higher speeds.

Low-Profile Mounted Ball
Bearings with Two-Bolt Flange

Designed with a thin, compact housing, these bearings are good for space-constrained applications.

Washdown Mounted Ball
Bearings with Two-Bolt Flange

Used in food, beverage, pharmaceutical, and chemical plants, these mounted ball bearings are IP69K certified for washdown environments and have a two-bolt flange for mounting.

High-Speed Mounted Ball
Bearings with Two-Bolt Flange

These bearings have the highest speed ratings of any mounted ball bearing in our offering.

Permanently Lubricated Washdown
Mounted Ball Bearings with Two-Bolt Flange

Permanently lubricated and IP69K certified for washdown environments, these mounted ball bearings are useful for hard-to-reach areas in food, beverage, pharmaceutical, and chemical plants. Mount them using their two-bolt flange.

Easy-Align Mounted Ball
Bearings with Two-Bolt Flange

An elongated mounting hole on one side of the flange lets you adjust the position of these bearings without having to remove your shaft.

Mounted Ball Bearings with Four-Bolt Flange

A bolt in each corner makes for a secure, even hold.

Permanently Lubricated Washdown
Mounted Ball Bearings with Four-Bolt Flange

Made to withstand frequent washdowns, these bearings are permanently lubricated, which means you’ll never have to add lubricant. Use them in hard-to-reach areas in food, beverage, pharmaceutical, and chemical plants.

High-Speed Mounted Ball
Bearings with Four-Bolt Flange

These bearings have the highest speed ratings of any mounted ball bearing in our offering.

Mounted Bearings with Three-Bolt Flange

With all three mounting holes on one side, you can position the bearing above or below the mounting surface.

Insert Bearings

Swap out worn inserts instead of replacing the entire mounted unit.

Shim Sets for Keyed Shafts

Be prepared with shims in a variety of thicknesses. Also known as arbor spacers, these shims are notched to fit over keyed shafts.

Bearing Adapter Sleeves

Make up for imperfections and gaps between your bearing and shaft for a tight fit.

Bushings for Chain and Belt Drives

Flush-Mount Screw-Clamp Bushings

Insert these bushings into the bore of your sprocket for flush or recessed mounting.

Self-Centering Screw-Clamp Bushings

A mounting flange prevents movement during tightening, so it's easy to center these bushings in your sprocket.

Self-Adjusting Spring Bushings

A toothed slot lets these bushings contract for insertion into the bore of your sprocket or pulley and then expand for a snug fit.

Quick-Disconnect (QD) Bushings

The screw connections on these bushings easily mate to compatible quick-disconnect sprockets and pulleys.

Split-Tapered Bushings

The tapered barrel on these bushings is split on both sides, allowing them to contract more tightly around the shaft than quick-disconnect and taper-lock bushings.
