Support radial and thrust loads at the same time. These bearings are often found inside equipment such as gearboxes and pumps. For example, a bearing inside a gearbox withstands a radial load when the gear is engaged and a momentary thrust load when you shift to a new one. While they don't handle as much force from radial loads as standard bearings, you can pair them with a cylindrical roller bearing to increase their load capacity.
Double Row—Double-row bearings handle thrust loads from both directions.
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.
