Metal Bearings | McMaster-Carr

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.

High-Load Ball Bearings

Wider than our standard ball bearings, these rugged bearings are good for handling heavy loads at low speeds.

Hex-Bore Ball Bearings

Mount these bearings onto a hex shaft.

Self-Aligning Ball Bearings

With a spherical raceway and two rows of balls, these bearings compensate for shaft misalignment.

One-Way Locking
Ball Bearing Clutches

Internal locking elements (sprags) lock to transmit torque in one direction while turning freely in the other direction.

Electrically Insulated Ball Bearings

Good for use in electric motors and power generators, these bearings have ceramic balls that insulate against stray current to prevent damage to the bearing.

Precision Ball Bearings

For greater accuracy and higher speeds, these bearings are made to tighter tolerances than standard ball bearings.

Plastic Ball Bearings

Made of slippery plastic, these bearings do not require lubrication and have excellent corrosion and chemical resistance.

Water-Resistant Plastic Ball Bearings

Made of PVDF, these bearings resist moisture absorption, so they won’t warp in underwater applications.

High-Temperature
Plastic Ball Bearings

These PEEK bearings operate in temperatures almost twice as high as our other plastic ball bearings.

High-Load Plastic Ball Bearings

With two rows of balls, these lightweight bearings have greater durability and load capacity—and a wider profile—than single-row plastic bearings.

Stainless Steel Ball Bearings

Permanently Lubricated
Stainless Steel Ball Bearings

A solid polymer lubricant surrounds the balls, eliminating the need for additional lubrication. Bearings are 440C stainless steel.

Food Industry Permanently Lubricated
Stainless Steel Ball Bearings

Good for applications with incidental food contact, these 440C stainless steel bearings have a food-grade, solid polymer lubricant between the balls and race that eliminates the need for additional lubrication.

Stainless Steel Ball Bearings

Bearings are 440C stainless steel for good corrosion resistance.

Ultra-Corrosion-Resistant
Stainless Steel Ball Bearings

These 316 stainless steel bearings are more corrosion resistant than our other stainless steel bearings, but they have a lower load capacity.

Precision Stainless
Steel Ball Bearings

Made to tight tolerances, these 440C stainless steel bearings combine speed and accuracy with corrosion resistance.

Panel-Mount Ball Bearings

Unlike other ball bearings, these do not need to be fully inserted into a housing. A spline around the outside of the bearing creates a permanent, secure hold in thin panels.

Flanged Ball Bearings

The flange ensures proper positioning inside a tube or housing.

Lubrication-Free Plastic
Flanged Ball Bearings

Install these acetal bearings in caustic environments and where lubrication can’t be used. They have good all-around corrosion and chemical resistance.

Precision Flanged Ball Bearings

When speed and accuracy matter most, opt for these bearings. They’re made to tighter tolerances than standard flanged ball bearings.

Self-Aligning Flanged Ball Bearings

No need to worry about precisely aligning these bearings—they swivel to compensate for up to 5° of shaft misalignment.

Set Screw Collar Ball Bearings

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

Ball Bearings for Combined Loads

Ultra-Thin Ball Bearings

With twice as many contact points as angular-contact ball bearings, these bearings resist any combination of radial, thrust, and moment loads.

Angular-Contact Ball Bearings

The raceways in these bearings are positioned off-center to handle angular (combined radial and thrust) loads.

Flanged Ultra-Thin Ball Bearings

Flanged and creating twice as many contact points as angular-contact ball bearings, these bearings ensure correct positioning within a tube or housing and resist radial loads.

Thrust Ball Bearings

Corrosion-Resistant
Thrust Ball Bearings

A combination of stainless steel and nylon components provide increased corrosion resistance over standard thrust ball bearings.

Thrust Ball Bearings for Shaft Ends

Use these bearings as miniature high-precision turntables. They have a unique design that allows your shaft to sit on top of the bearing rather than being inserted through it.

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.

Thrust Ball Bearings

Steel balls and washers allow these bearings to handle higher loads than bearings with stainless steel components.

Sleeve Bearings

Multipurpose Sleeve Bearings

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

Multipurpose Sleeve
Bearings with Groove

A figure-8-shaped groove provides a flow path for lubricant, distributing it evenly along the bearing’s surface.

Corrosion-Resistant 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.

Corrosion-Resistant Sleeve
Bearings with Groove

Grooves on the inside of the bearing provide a flow path for lubricant, distributing it evenly along the bearing’s surface.

Panel-Mount Oil-Embedded
Sleeve Bearings

Unlike other sleeve bearings, these do not need to be fully inserted into a housing. Their unique shape creates a permanent, secure hold in thin panels.

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.

Oil-Embedded Sleeve Bearings

Also known as Oilite® bearings.

Vibration-Damping
Oil-Embedded Sleeve Bearings

With a flexible layer of rubber sandwiched between an oil-embedded bronze bearing and rigid metal shell, these bearings reduce wear and machinery noise.

Ultra-Low-Friction
Oil-Embedded Sleeve Bearings

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