Needle-Roller Thrust Bearings

Bearings

Washers

Small but mighty, our thinnest rolling thrust bearings slot into tight spaces and spin at whirring speeds. Their long, slender rollers support thrust loads and reduce friction in everything from machine tool spindles to gearboxes.

A cage holds the rollers in place. You can install these bearings without washers between hardened, ground surfaces for the thinnest profile. If you’re working with unhardened, unground surfaces, you’ll need two washers for the rollers to run on. This three-piece design is easy to lubricate, but the oil will attract dust and grime since it’s exposed.

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

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.

High-Load Cylindrical-Roller Thrust Bearings

Thick, pop-can-shaped rollers balance strength and speed. These bearings reduce friction and support heavier loads than ball or needle-roller thrust bearings.

They come as three separate pieces—one cage and two washers. The cage holds the rollers in place, while the washers create a surface for the rollers to run on. This design is easy to lubricate, but the oil will attract dust and grime since it’s exposed.

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