For example: 6203, what do these numbers mean?
First digit: 0 denotes double-row angular contact ball bearings; 1 denotes self-aligning ball bearings; 2 denotes self-aligning roller bearings and thrust self-aligning roller bearings; 3 denotes tapered roller bearings; 4 denotes double-row deep groove ball bearings; 5 denotes thrust ball bearings; 6 denotes deep groove ball bearings; 7 denotes angular contact bearings; 8 denotes thrust cylindrical roller bearings. N denotes cylindrical roller bearings and double-row cylindrical roller bearings. NN U denotes outer spherical bearings. QJ denotes four-point contact ball bearings
6203:6 is a type code indicating the deep groove ball bearing 6000 series. 2 is the size series code, 03 is the inner diameter code; 03 represents 17 mm
Who has the latest standards for this bearing? I can’t find them anywhere. Please help, thank you
It’s in the hardware manual; you can check it there yourself
