The general dimensions of four point contact ball bearings are standardised by DIN 628-4 (Rolling bearings - Angular contact radial ball bearings - Four point contact bearing) for type QJ and based on the standard of TGL2982 for type Q. Dimensions and tolerances of the holding grooves are standardised by ISO 20515 (Radial bearings - holding grooves).
