The symbols used in the tolerance table are explained in the following:
| d | = | nominal bore diameter
|
| Δdmp | = | deviation of the mean bore diameter from the nominal in a single plane
|
| ΔBs | = | deviation of a single inner ring width from the nominal
|
| D
|
= | nominal outer diameter
|
| ΔDmp | = | deviation of the mean outer diameter from the nominal in a single plane
|
| ΔCs | = | deviation of a single outer ring width from the nominal
|
