    Extreme-Temperature Mounted Sleeve Bearings

    Image of Product. Front orientation. Contains Annotated. Mounted Bearings. Extreme-Temperature Mounted Sleeve Bearings.
    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 bolts down to support shafts as they turn.
    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.

    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.

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

    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.
