0.624" ID Bearings | McMaster-Carr

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.

Dry-Running Mounted Sleeve Bearings with Two-Bolt Flange

Leave the lubricant in the supply closet—these low-maintenance bearings are made from naturally slippery plastic. They'll keep shafts spinning with no messy grease to drip off, wash out, or collect dust. With no moving parts, sleeve bearings stand up to grimy environments better than ball bearings. However, with more friction generated, they're less effective at high speeds. The sturdy housing supports the shaft and secures with a two-bolt flange, the most common type of flanged bearing.

High-Load Bronze-Backed PTFE—Reinforced with metal, these slick PTFE bearings carry load ratings at least seven times greater than any plastic alternative. The slippery material is a good fit for conveyors and other machinery with frequent starts and stops.

Aluminum Housing—One-third the weight of cast iron but not as strong. Aluminum also resists corrosion.

Misalignment Capability—Bearings compensate for as much shaft misalignment as the degree listed. This extends the life of the bearing and protects against wear if shafts are slightly askew.

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.

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.

Weldable 4130 Alloy Steel Round Tubes

Also known as chrome-moly steel, these 4130 alloy steel round tubes have low carbon content for good weldability. They’re often used for roll cages and frames. To increase their wear resistance, you can harden them with heat treating.

Highly Corrosion-Resistant 316 Stainless Steel Round Tubes

One of the most corrosion-resistant types of stainless steel, 316 stands up to the harshest chemicals, including bleach, chlorine, and phosphoric acid. It's a step up from 304, which has similar strength and temperature performance. Use it in a variety of marine and chemical-processing applications. It maintains its corrosion resistance in temperatures up to 1500° F.

316/316L Stainless Steel—Dual certified to meet both 316 and 316L requirements. The low carbon content makes this stainless steel easy to weld while maintaining strength and corrosion resistance.
