2 1/2" Housing ID Bearings

Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.

Shielded—The balls are covered just enough to keep out large particles while allowing air to pass through and dissipate heat.

Sealed—The best choice for dirty environments. A barrier seals out dust so it won't gunk up or wear down the balls. However, these bearings retain the most heat since air can't flow through.

Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

Ball Bearings

Open

Shielded

Smoother than smooth—the balls inside these bearings roll nearly friction free. You’ll often find them on rapidly rotating parts, from the whirring chuck on a power drill to the spinning shaft on an electric motor.

Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.

Shielded—The balls are covered just enough to keep out large particles while allowing air to pass through and dissipate heat.

Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

ABEC Rating—Bearings with an ABEC rating meet industry tolerance standards established by the Annular Bearing Engineers Committee (ABEC). They're rated on a scale from 1 to 9. The higher the rating, the tighter the tolerance. Bearings rated ABEC 1 or 3 are precise enough for most applications. If your application consistently runs at high speeds or requires high accuracy, consider bearings rated ABEC 5 or higher, since they generate less friction and heat.

Four-Point Angular Contact Ball Bearings

Support complex movement in multiple directions with a single compact bearing. The balls distribute weight at four points, so these bearings handle radial, thrust, and moment loads all at once. For example, you’ll often find them in robot arms, which rotate, extend, and twist while supporting an object’s weight. Thinner than two standard angular contact ball bearings paired together, these bearings squeeze into tight spaces. They’re commonly paired with large hollow shafts to run electrical wire and other lines.

Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.

Permanently Lubricated Ball Bearings

Install and forget these self-lubricating bearings. Their lubricant is a solid material that fills the space between the balls and releases oil over time, so you'll never need to add more.

Sleeve Bearings

These bearings don’t come with a lubricant, so you can select the oil that meets the needs of your application. You’ll need to refill the oil, so make sure the bearing is located where you can access it. All are fabricated and inspected in the U.S.

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.

High-Strength 932 Bearing Bronze—These bearings are strong enough for sudden starts and stops, plus they resist wear and tear. They are cast from an alloy of leaded tin bronze for uniform rigidity and strength. Also known as 660 leaded bronze bearings.

High-Strength Chemical-Resistant 954 Bearing Bronze—The strongest of our bronze bearings. The addition of iron and aluminum makes them exceptionally strong and resistant to chemicals. They’re often used in the most demanding environments, such as salt mines. Also known as aluminum bronze.

Oil-Embedded Sleeve Bearings

Install and forget these self-lubricating bearings. All are made from porous metal and saturated with oil to reduce maintenance and downtime. A good all-around choice, they are used in everything from palm-sized fans in electronics to tire-sized pulleys. Although these bearings will work in most conditions, oil may drip away if temperatures get too high. Consider a graphite-lubricated bearing for higher temperatures or places where you can’t afford the mess. All are fabricated, lubricated, and inspected in the U.S.

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.

841 Bearing Bronze—A classic choice for a starter pick. Also known as SAE 841 bearings.

High-Strength 863 Iron Copper—Iron makes these bearings harder, stronger, and more resistant to sudden starts and stops than 841 bearing bronze. However, they operate at slower speeds. The increased iron content makes these bearings appear silver.

Synthetic Oil Base—A high-quality lubricant makes all the difference. Synthetic oil is less sensitive to temperature changes than mineral oil, so it won't get runny and leak away at higher temperatures. Also known as Oilite® bearings.

Dry-Running 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.

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.

High-Strength Ultra-Chemical-Resistant Polyester Fabric-Reinforced PTFE—Woven polyester resin reinforces these PTFE bearings to support loads and speeds comparable to metal bearings. Similar to other PTFE options, they are unaffected by the harsh fluids that other plastics can't handle, including all strong acids and bases.

High-Temperature Graphite-Lubricated Sleeve Bearings

Made of a graphite and metal alloy, these bearings stay slippery at high temperatures where oil burns off and other bearings fail. With no need for refills, they require little to no maintenance. You’ll find them in pumps, propellers, and mixers that spin near steam or inside ovens. However, graphite may eventually flake off, dropping flecks and leaving smudges. If you need a spic-and-span space, consider dry-running bearings made of slippery plastic instead. All are fabricated, lubricated, and inspected in the U.S.

Grooved Sleeve Bearings

A figure-8-shaped groove provides a flow path for lubricant and distributes it evenly inside the bearing’s surface. A refill hole on the outside lets you inject your lubricant straight into the groove. These bearings don’t come with a lubricant, so you can select the oil that meets the needs of your application. You’ll need to refill the oil, so make sure the bearing is located where you can access it. All are fabricated and inspected in the U.S.
