0.376" OD Bearings | McMaster-Carr

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-Load 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.

Dry-Running Flanged 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.

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.

High-Load Moisture-Resistant Rulon LR—Won’t swell in wet or humid places, similar to acetal, but can support higher loads. These bearings also operate smoothly from cryogenic to oven-like temperatures.

Ultra-Low-Friction Rulon J—These bearings glide effortlessly for applications with frequent starts and stops, such as conveyor systems.

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.

PTFE with Aluminum Shell—A lightweight upgrade from our steel shell. These bearings also offer good corrosion resistance similar to stainless steel but aren’t as strong.

Oil-Embedded Sleeve Bearings for Food and Beverage

These lead-free bearings are infused with a food-grade oil that is odorless, colorless, tasteless, and safe for unintended contact with food. They’re often used in food and beverage processing, packing, and handling equipment. All are made from porous metal and saturated with oil to reduce maintenance and downtime. If you need a bearing rated for contact with food, consider dry-running sleeve bearings for food and beverage. 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.

Dry-Running Sleeve Bearings for Food and Beverage

Made of plastics permitted by the US FDA for contact with food, these bearings won’t release harmful, smelly, and distasteful impurities into your food or beverage production line. These self-lubricating plastics eliminate the need for oil, resulting in less maintenance and improved hygiene. You’ll find them inside food-processing equipment such as mixers, conveyors, and fillers.

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.
