ISO 15:1998
Rolling bearings - Radial bearings - Boundary dimensions, general plan
This international standard lays down preferred boundary dimensions for radial bearings.
Tapered roller bearings, insert bearings and some types of needle roller bearings, airframe bearings and instrument precision bearings standardized by ISO do not conform to this general plan because the dimensions given were not found to be optimal for the bearings in question.
