The main difference between the 60 series and 62 series bearings lies in their size specifications: for the same inner diameter, the outer diameter and width of the 62 series bearings are usually larger, providing higher load-bearing capacity and applicability. This size difference is the key factor distinguishing the two series.

Comparison of Size Differences

The series numbers of deep groove ball bearings (such as 60 series, 62 series) directly reflect their size design. According to the classification standards for bearing models, there are significant differences in outer diameter and width between the 60 series (6000 series) and 62 series (6200 series) with the same inner diameter.

Dimensional regularity

The outer diameter and width of the 62 series are generally 4-5mm larger than those of the 60 series, due to its design optimization to enhance load-bearing capacity. ‌‌

Example verification

The 6000 bearing with an inner diameter of 10mm has an outer diameter of 26mm, while the 6200 bearing has an outer diameter of 30mm; the 62/32 bearing with an inner diameter of 32mm has an outer diameter of 65mm, corresponding to the 60 series without this inner diameter specification. ‌‌
