Swap out worn inserts instead of replacing the entire mounted unit. To choose an insert, match the manufacturer model number on your existing bearing.

Set-Screw Shaft Mount—Tighten the screws against the shaft to hold the bearing in place, regardless of the direction the shaft spins.

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.
