2302 Bearings | McMaster-Carr

Misalignments correct themselves on the fly in these bearings. Two rows of balls have separate raceways in the inner ring and a shared raceway in the outer ring, so the balls rock back and forth to compensate for misalignment. This construction also reduces noise and vibration.

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

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

ABEC Rating—Bearings with an ABEC rating meet industry tolerance standards established by the Annular Bearing Engineers Committee (ABEC). They're rated on a scale from 1 to 9. The higher the rating, the tighter the tolerance. Bearings rated ABEC 1 or 3 are precise enough for most applications. If your application consistently runs at high speeds or requires high accuracy, consider bearings rated ABEC 5 or higher, since they generate less friction and heat.
