PART 2
--
TOLERANCE CLASSES 6, 5 AND 4
1. SCOPE
1.1 This IS0 Recommendation applies to the tolerances of thrust ball bearings with flat seats
-
tolerance classes 6 and 5 for bore diameters up to and including 1250 mm, given
in Table 1, and
-
tolerance class 4 for bore diameters up to and including 800 mm, given in Table 3.
1.2 The housing washer outside diameter tolerances are those given for the normal tolerance class
in IS0 Recommendation R 199, Rolling bearings - Thrust ball bearings with flat seats ~
Normal tolerances,
1.3 The cylindrical bore diameter “not go side” tolerance limit does not necessarily apply within a
e
distance of twice the nominal washer chamfer dimension from the washer face.
2. SYMBOL
I
The following symbol is used in the Tables :
d = bore diameter of shaft washer of single and double direction thrust ball bearings.
