(1) miniature bearings - nominal diameter size range of 26mm below the bearing;
(2) small bearings - nominal diameter size range of 28-55mm bearing;
(3) small and medium sized bearings - nominal diameter size range of 60-115mm bearing;
(4) in the large bearing - nominal diameter size range of 120-190mm bearing
(5) large bearings - nominal diameter size range of 200-430mm bearing;
(6) extra large size bearing, nominal diameter range of 440mm or more.
Deep groove ball bearings can be used for gear box, instrument and meter, motor, household appliances, internal combustion engine, transport vehicles, agricultural machinery, construction machinery, engineering machinery, roller skates, yo yo.
