Hello guys

Let me start at first i bought two cheap very cheap bearings and one of them crap out after one week (no surprise here ) changed to napa bearing and its good , now second one is getting bad so i bought SKF BR930184 and i received it today upon inspection the bearing feels gritty when i turn it by hand but when i got to skf website it says this is normal did any of you experienced that ?
