It is an open ball bearing (17 mm id, 35 mm od, 17 mm thick ,NSK6207 C3 or KOYO 6207R) and when you are installing your supposed to pack the bearing itself with grease and also add grease in the housing (where the spacer is). I don't understand how adding grease to the housing helps, I can't see how grease there is supposed to get into the bearing.
