Antifriction bearing

An antifriction bearing comprising:

• a conical raceway;
• a cylindrical raceway;
• a cage;
• a plurality of rolling elements arranged in the cage and positioned between the conical raceway and the cylindrical raceway to roll along the cylindrical raceway and the conical raceway, each rolling element having an outer surface possessing a conical shape;
• the outer surface of each rolling element forming an angle with a center axis of the rolling element that is 3° at maximum;
• and
• the outer surface of each rolling element having a convex curvature that is superimposed on the conical shape.

An antifriction bearing arrangement, comprising:

• a first machine element;
• a second machine element;
• an antifriction bearing positioned between the first and second machine elements, the antifriction bearing including a plurality of rolling elements each having opposite end faces and an outer surface possessing a conical shape, the rolling elements being adapted to roll along a conical raceway and a cylindrical raceway;
• the lateral surface of each of the rolling element forming an angle with a center axis of the rolling element that is 3° at maximum;
• the lateral surface of each rolling element having a convex curvature that is superimposed on the conical shape;
• a stop element having a stop face contacted by one of the end faces of each of the rolling elements.
