1) For matched sets of angular contact ball bearings, multiply the lower tolerance limit value by the number of bearings in the set.
2) Valid for steel supports with standard bearing radial clearance.
3) Valid for unmounted radial contact and four-point contact ball bearings under zero measuring load.
