Extreme-Load Tapered-Roller Thrust Bearings

With thick, tapered rollers, these thrust bearings are the strongest we offer. The rollers spin inside a raceway instead of a cage, so there’s room for more rollers to support higher loads than three-piece designs. You’ll often find them on crane hooks and kingpins that connect semi-trailers to semi-tractors. However, they rotate at a fraction of the speed of other roller thrust bearings.

Since they come as one piece, you don’t need to assemble cages and washers to install. An outer band holds the rollers inside the raceway, keeping lubricant in and dirt out.

Steel—Strong and wear resistant. However, these bearings are best for dry environments since moisture will cause them to rust.

Open—With no rubber seal to block airflow, these bearings dissipate heat quickly, extending the life of the lubricant and reducing friction over time.

Sealed—The best choice for dirty environments. In addition to a band, these bearings also have a rubber seal to block dust from creeping in and wearing down the rollers. However, they retain the most heat since air can’t flow through.

One-Piece Thrust Ball Bearings

No need to assemble cages and washers—these thrust ball bearings come as one piece for easy installation. The balls spin inside a raceway instead of a cage, so there's room for more balls to support higher loads than three-piece bearings. An outer band holds the balls inside the raceway, keeping lubricant in and dirt out.

Oil-Embedded Thrust Bearings

Our simplest-to-use thrust bearings, with no moving parts and no need to lubricate. Their porous surface releases oil over time, so you can install and forget them. While they run in most conditions, oil may drip away if temperatures climb too high. For extremely hot environments, consider graphite-lubricated bearings. All are fabricated, lubricated, and inspected in the U.S.

841 Bearing Bronze—A balance of strength and speed makes these bearings a good choice for most applications. Also known as SAE 841 bearing bronze.

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 if the bearing heats up.
