Normal grade P0 radial bearing bore tolerance

Deep groove ball bearing is the most common type of rolling bearing.The basic type of deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of retainers.
In general, the bearing bore tolerance is 0, and the lower tolerance is a negative value.For deep groove ball bearing 6206, the inner hole diameter is 30mm, the deviation is 0~-0.01mm;The outside diameter of the bearing is 62mm, and the deviation is 0~-0.013mm.Specific bearing bore tolerance are determined according to the bearing's accuracy grade and basic dimensions in accordance with the standard.
This is some introduction for bearing bore tolerance:

Bearings bore tolerance grade:
Normal grade P0 radial bearing bore tolerance:
18-30 bearing bore tolerance is 0~-0.01, outer diameter 18-30 tolerance is 0~-0.009
Tolerance of the inner ring of 30-50 bearings is 0~-0.012, and tolerance of the outer diameter 30-50 is 0~-0.011
50-80 bearing bore tolerance is: 0 ~ 0.015, the diameter tolerance is from 50-80:0 ~ 0.013 P2 level the bearing inner ring diameter from 18 to 30 tolerance is: 0 ~ 0.005, outer diameter from 18 to 30 tolerance is: 0 ~ 0.005
30-50 bearing bore tolerance is 0~-0.006 and tolerance of bearing outer diameter 30-50 is 0~-0.006

Tolerance of inner ring of bearing with inner diameter 50-80 is 0~-0.007, tolerance of outer diameter 50-80 is 0~-0.007, tolerance of inner ring of bearing with inner diameter of P5 class 18-30 is 0~-0.006, tolerance of outer diameter 18-30 is 0~-0.006
Tolerance of bearing inner ring with internal diameter 30-50 is 0~-0.008 and tolerance of bearing outer diameter 30-50 is 0~-0.007
Tolerance of inner ring of bearing with inner diameter 50-80 is 0~-0.009 and tolerance of outer diameter 50-80 is 0~-0.009
