ISO 12297-2:2018
Rolling bearings — Cylindrical rollers — Part 2: Boundary dimensions, geometrical product specifications (GPS) and tolerance values for ceramic rollers
ISO 12297-2:2018 specifies dimensional and geometrical characteristics, nominal boundary dimensions and tolerance values for finished silicon nitride cylindrical rollers for rolling bearings.
Annexes A and B give the sorting principles for roller diameter and roller length tolerances and gauges, respectively.
Annex C gives examples of imperfection types and methods of inspection.
