Answer / nihar ranjan

Commonly 4 or 5 nos. appears in the bearing outer cage, The designation is for recognizing the type & size of bearing. e.g, 6305 .
1st two nos. 63 series used for deep groove ball bearing,
last two no. 05 for bearing bore size . But every time we need to multiple the no. by 5. So here in this case bearing size will be 05X5= 25 i,e 25 mm.
If there are any suffix , like RS or 2Z or Z ,etc then it is used for type of sealing used.
RS for rubber seal,
Z for metallic(one side)
2z for both side metallic.
