Dynamically aligning, maintenance free, radial insert ball bearing

A dynamically aligning, maintenance-free radial insert ball bearing, comprising:

• an inner ring having an inner race;
• an outer ring having an outer race, an outer surface of the outer ring having a partial spherical contour;
• an enclosure ring located about the outer ring having an inner surface with a complementary shaped contour to the partial spherical contour, such that the outer ring is axially tiltable relative to an axis of the enclosure ring via sliding contact of the partial spherical contour in the complementary shaped contour on the inner surface of the enclosure ring;
• rolling elements located between the inner and outer bearing rings and contacting the inner race and the outer race;
• first and second inner seals located on opposing sides of the rolling elements and extending between the inner ring and the outer ring;
• first and second outer seals located on opposing sides of the rolling elements axially outward from the respective first and second inner seals and extending between the enclosure ring and the inner ring to define a lubricant reservoir for the sliding contact of the partial spherical contour in the complementary shaped contour on the inner surface of the enclosure ring.
