When it comes to SKF bearing tolerance, there are different tolerance classes, such as P2, P3, P4, P5, P6 and so on. The SKF bearing tolerance has been standardized internationally. SKF bearing tolerance range:

CLN/no rmal = ABEC1
P6 = ABEC3
P5 = ABEC5

In addition to normal tolerances the ISO standards also cover closer tolerances as well, for example:

tolerance class 6 which corresponds to SKF bearing tolerance class P6
tolerance class 5 which corresponds to SKF bearing tolerance class P5.

For special applications, such as machine tool spindles, SKF also manufactures bearings with higher accuracy, e.g. to tolerance classes P4, P4A, P7, PA9A, P9, SP, SPC and UP. Fo r instance: Single row deep groove ball bearings are commonly manufactured to no rmal tolerance class.  However, for special applications demanding high accuracy or speed ,  these bearings in higher tolerance classes P6, P5 o r P4  need  to be used.

The actual SKF bearing tolerances are provided in the tables referenced in the following.
1.  Metric radial bearings (except tapered roller bearings):
No rmal, P6, P5, P4, P4A,P7, P2, SP, UP, PA9A,P9.

2. Inch radial bearings (except tapered roller bearings): Normal
3. Metric tapered roller bearings:
4. No rmal, CL7C, CLN(ISO class 6X), P6, P5.
5. Inch tapered roller bearings:No rmal,CL2, CL3, CL0.
6. Metric thrust bearings:No rmal, P6, P5, P4, SP, UP, SPC.
7. Tapered bo res with taper 1:12: No rmal, P6, P5.
