The angular touch ball bearing is mainly used on the machine tool spindle. In most cases, the outer ring of the bearing has a locking ring; therefore, the annular groove thus formed cannot be sealed; so that many angular touch ball bearings used on the machine tool spindle cannot It is used to add smooth grease like other bearings on the other mainframe. If it is equipped with a set of auxiliary smoothing system; it is necessary to add the cost; and make the machine layout more messy.
FAG's Barden division has dealt with this problem. The advanced method is to embed a new type of grooved seal into the bearing; the groove is slightly shallower than the gauge bearing; and is just adapted to intersect; Fill in the gap left by the outer ring flange. Participating in this sealing ring can prevent the smooth grease from leaking from both ends of the bearing; it can also block the intrusion of dirt from the two ends of the bearing.
