Deep Groove Ball Bearing Finder — 6000, 6200, 6300 Series by Bore, Outside Diameter, Width and Seal Variant (2RS, 2Z, Open)

Deep Groove Ball Bearing Finder

Deep groove ball bearings are identified by the ISO designation (6000 extra-light, 6200 light, 6300 medium, 6400 heavy series; the last two digits × 5 give the bore in mm from 04 upwards) and by suffixes: 2RS/2RSH/2RS1 (two rubber contact seals), 2Z/ZZ (two steel shields), open (no seal), C3 (increased radial clearance for higher temperature or interference fits) and E (reinforced). The finder lists the catalogue bearings with bore d × outside diameter D × width B so a replacement can be selected from dimensions alone when the marking is unreadable.

Sealed bearings (2RS) are lubricated for life and limited to about 100 °C and the lower speed rating; shielded bearings (2Z) run faster and are used where contamination is light. C3 clearance is the usual choice for electric motors. Interchangeability across SKF, FAG/Schaeffler, NSK, NTN and Timken is by designation: the same basic number and equivalent suffix denote the same dimensions.

Coverage: 1,300 of 2,053 catalogue rows with a readable size are listed (4,318 rows in these categories in total; the remainder can be found through the site search by part number).
