Question about my mill spindle bearings. - Practical Machinist

16/9/2005· I have a Grizzly mill G3103. If I take the belt off the pulleys, grab the 6 inch pulley with my hand, and give the spindle a good spin from the top, it will only rotate 1.5 turns until friction makes it stop. Should it not spin as if it were on bearings? So is this normal, or bad?

Bearing Arrangement - an overview | ScienceDirect Topics

10.10.1 Introduction. Whatever the bearing arrangement or type of bearing used, the bearings must be sealed to prevent contaminants and moisture entering the bearing in addition to retaining the lubricant. When seals are an integral part of a rolling element bearing, the bearing can be greased and sealed for life.
