2 5/8" OD Bearings | McMaster-Carr

Our simplest-to-use thrust bearings, with no moving parts and no need to lubricate. Their porous surface releases oil over time, so you can install and forget them. While they run in most conditions, oil may drip away if temperatures climb too high. For extremely hot environments, consider graphite-lubricated bearings. All are fabricated, lubricated, and inspected in the U.S.

841 Bearing Bronze—A balance of strength and speed makes these bearings a good choice for most applications. Also known as SAE 841 bearing bronze.

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

Extreme-Load Heat-Treated Iron Copper—Our strongest oil-embedded thrust bearings. They're heat treated to form a uniform internal grain that makes them stronger than 863 iron copper. As a result, they're often used to support extreme loads in earth-moving equipment and railroad applications. The increased iron content also makes them appear silver.

Mineral Oil Base—Mineral oil consistently lubricates at most temperatures but doesn’t last as long as synthetic oil.

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 if the bearing heats up.

Dry-Running Metal-Reinforced Plastic Thrust Bearings

Combine naturally slippery PTFE with the strength of metal. These bearings don't need lubricant, so there's no oil to maintain, drip off, or attract dust. Backed with steel, they're as strong as other all-metal thrust bearings. However, they're best for dry environments since moisture will cause the steel to rust.

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.

Nylon—A balance of wear resistance and slipperiness. These bearings are best for dry environments since they swell and weaken when exposed to moisture.

Chemical-Resistant Flange-Mounted Linear Sleeve Bearings

The Frelon liner on these bearings allows them to stand up to a wider range of chemicals than other flange-mounted linear sleeve bearings. All are self-aligning to compensate for shaft misalignment and are for use with round end-supported shafts. Note: Not for use with bare aluminum or chrome-plated shafts.

0.0005" Shaft Clearance—Bearings with 0.0005" shaft clearance are best for precision applications.

0.0015" Shaft Clearance—Bearings with 0.0015" shaft clearance are less likely to bind on your shaft than bearings with 0.0005" shaft clearance.

Thrust Bearings

With no moving parts, these bearings are the plainest way to support thrust loads while reducing friction. They don't come with lubricant, so you can choose the oil that's best for your application. Make sure to mount them where they're easy to access, since you'll need to replenish the oil frequently. All are fabricated and inspected in the U.S.

High-Load 932 Bearing Bronze—Cast from an alloy of leaded tin bronze for uniform rigidity and strength. Also known as 660 leaded bronze.

High-Load Chemical-Resistant 954 Bearing Bronze—The addition of iron and aluminum makes these bearings strong and exceptionally chemical resistant. You'll find them in demanding environments, such as salt mines. Also known as aluminum bronze.

Ultra-Low-Friction Oil-Embedded Thrust Bearings

Our slipperiest metal thrust bearings glide on machines with frequent starts and stops, such as conveyors. Their oil contains nonstick PTFE particles that reduce wear and heat, extending the life of your equipment. All are fabricated, lubricated, and inspected in the U.S.

Oil-Embedded Thrust Bearings for Food and Beverage

Infused with food-grade oil, these bearings are safe for incidental contact with food. The oil is odorless, colorless, and tasteless, so they're common on food production and packaging lines. You can install and forget them since their porous surface releases oil over time. All are fabricated, lubricated, and inspected in the U.S.

If you need a bearing rated for direct contact with food, consider dry-running thrust bearings for food and beverage.
