2 5/16" Housing ID Bearings

Double rows of tapered bearings support large shafts with heavy loads. They also handle thrust loads in either direction as well as radial loads. All come assembled and ready to use.

Precision Needle-Roller Bearings


	Bearing

Install these bearings directly onto hardened and ground shafts. They have higher load capacity, speed, and accuracy than standard needle-roller bearings.

Open Bearing—Open bearings dissipate heat more efficiently than sealed bearings.

Sealed Bearing—Sealed bearings block out dust and other contaminants better than open bearings, but retain more heat.

Shaft Liners—Shaft liners allow you to use the bearing on unhardened and unground shafts.

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.

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.
