1.004" ID Bearings | McMaster-Carr

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-Load 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.

Extreme-Temperature Mounted Sleeve Bearings with Four-Bolt Flange

From cryogenic chill to heat-treating furnaces, these bearings endure it all. Made to glide in temperatures from -400° to 750° F, they support shafts in conditions that seize or destroy other bearings. With graphite lubricant that never degrades, they require little to no maintenance.

With no moving parts, sleeve bearings stand up to dusty, dirty conditions better than ball bearings. However, with more friction generated, they're less effective at high speeds. The sturdy housing's four-bolt flange supports shafts with a stronger connection to the mounting surface than two-bolt alternatives.

Powder-Coated Cast Iron Housing—A rugged iron base coated in thick powder that protects against water, mild detergents, and oil. However, if the coating is scratched or chipped, the underlying iron may rust.

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.

Extreme-Temperature Mounted Sleeve Bearings with Two-Bolt Flange

With no moving parts, sleeve bearings stand up to dusty, dirty conditions better than ball bearings. However, with more friction generated, they're less effective at high speeds. The sturdy housing supports shafts and secures them with a two-bolt flange, the most common kind of flanged bearing.
