Bearing size chart

Dimensions of 72 deep groove ball bearings: the 60, 62, 63, 68 and 69 series from 10 to 60 mm bore and miniature bearings from 3 mm. For example, a 6205 is 25 × 52 × 15 mm. The last two digits give the bore: 00 = 10 mm, 01 = 12, 02 = 15, 03 = 17, and from 04 up multiply by 5.

Reading a bearing number

Using 6205 as the example.

Type and series

The first digit, 6, means a single-row deep groove ball bearing. The second digit is the dimension series: 0 extra-light, 2 light, 3 medium, 8 and 9 thin-section. For the same bore, a higher series has a bigger outside diameter and width and carries more load.

Bore code

The last two digits give the bore. 00, 01, 02 and 03 mean 10, 12, 15 and 17 mm. From 04 up, multiply by 5: 6205 has a 25 mm bore, 6310 a 50 mm bore. Under 10 mm the last digit is the bore itself, so 608 has an 8 mm bore.

Suffixes

ZZ or 2Z means metal shields on both sides; 2RS (and maker variants such as 2RSH, 2RSR, DDU and LLU) means rubber seals on both sides. C3 means greater internal clearance than normal. Suffixes never change the boundary dimensions.
