15.032mm ID Bearings | McMaster-Carr

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.

Washers for Needle-Roller Thrust Bearings

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.

Dry-Running Sleeve Bearings for Food and Beverage

Made of plastics permitted by the US FDA for contact with food, these bearings won’t release harmful, smelly, and distasteful impurities into your food or beverage production line. These self-lubricating plastics eliminate the need for oil, resulting in less maintenance and improved hygiene. You’ll find them inside food-processing equipment such as mixers, conveyors, and fillers.

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.

Moisture-Resistant Plastic Blend—Similar to UHMW, these bearings will keep their shape after washdowns but won’t hold up to steam cleaning. They're bright blue so they are easy to spot if they fall into your production line.

Dry-Running Flanged Sleeve Bearings for Food and Beverage

Flanged sleeve bearings combine a sleeve and thrust bearing in one. The flange supports thrust loads and prevents the bearing from being pushed out of place. The sleeve is the simplest way to support the load of a rotating shaft while reducing friction. Also known as plain bearings.
