7300 Series

7300 series bearings are single row, deep groove, radial ball bearings with ABEC 1, 3, 5, and 7 tolerances. They are angular contact bearings designed for medium duty.

7300 Series Bearings

Medium duty, angular contact ball bearing
Manufactured to ABEC 1, 3, 5 and 7 tolerances per ABMA Standard 20, typically from SAE 52100 steel. Other material options are available.
Standard contact angle is 30°. Other contact angle options are available.
Part numbers listed are an outer ring relieved configuration. Other design options are available.
Corner radius (r) is the maximum shaft or housing radius that bearing corners will clear.
