80.06mm ID Bearings | McMaster-Carr

These hardened steel washers protect softer shafts and housings from the rolling contact of needle rollers. Without them, needle rollers can indent and score unhardened surfaces, leading to premature wear and bearing failure. Positioned between the bearing and each mating surface, these washers distribute thrust loads evenly and extend service life. They adapt needle-roller thrust bearings for unhardened, unground surfaces.

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.
