Rolling Spherical ball bearing radial clearance
1 Scope
This standard specifies the radial clearance values \u200b\u200bspherical ball bearings and measurement principles.
This standard does not apply to blunt ends, spherical ball bearings, radial clearance values \u200b\u200bat both ends flat, spherical ball bearing according to GB/T 4604-
2006 provisions.

3 Definitions
Defined radial clearance GB/T 6930-2002 established in 05.08.01 apply to this standard.
4 Symbol
GB/T 7811-2007 symbols given apply to this standard.
5 Code
The standards required radial clearance code by JB/T 6640-2007 the provisions.
6 radial clearance values
6.1 Dimensions in line with GB/T 3882-1995 spherical ball bearing radial clearance values \u200b\u200baccording to Table 1, Table 2 provisions.
6.2 dimensions do not meet the GB/T 3882-1995 spherical ball bearing radial clearance values \u200b\u200bcan refer to 6.1 with the same diameter
Radial clearance values \u200b\u200bspherical ball bearings.
Principle 7 measuring radial clearance
7.1 Measurement of bearing radial clearance, it will be a tightening ring (ring can not be fixed work surface size and geometry has changed
Variable), the other ring is free to move in the diameter direction.
7.2 Each bearing radial clearance, should be separated by three 120 ° in the circumferential measurements, the arithmetic average of the three measurements is the sleeve shaft
Order of the value of the radial clearance.
7.3 measuring bearing radial clearance, should ensure that the bearing inner and outer ring axis of symmetry of the channel does not produce skew angle.
