Spherical roller bearing has ring-shaped sealing disk arranged on front side and is fixed on cage and abuts slidably at bearing rings, where sealing disk has sealing lips angled axially inward and outward at both radial ends

摘要

The spherical roller bearing (2) comprises a primary bearing ring (6), a secondary bearing ring (8) rotatable relative to the primary bearing ring around a rotation axis, multiple rolling elements (10) arranged between the bearing rings and held in a cage (12,14), and a ring-shaped sealing disk (4) arranged on the front side of the spherical roller bearing. The sealing disk is fixed on the cage and abuts slidably at the bearing rings. The sealing disk has a sealing lip angled axially inward at a radial end and another sealing lip angled axially outward at another radial end.
