    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 a knurled surface, these bushings grip plastic workpieces tightly so they don't wobble or slip. Use them to prevent through-hole alignment pins (sold separately) from binding while locating workpieces. Your first pin sits in one of these slotted bushings for precise locating in one direction. The second pin sits in a standard bushing for locating in every direction. This setup is similar to the pairing of round and diamond-head locating pins. They're also known as slotted locator bushings.
