What does 6003 mean?
6003 identifies a bearing in the 6000 dimensional series. For practical replacement work, the key fit dimensions are the bore, outside diameter and width. A part marked 6003 should therefore be checked against 17 × 35 × 10 mm before selection.
Suffixes such as seals, shields, internal clearance or manufacturer-specific variants can change construction or operating characteristics even when the principal dimensions remain the same. Confirm the exact manufacturer designation for critical applications.
