Abstract: A ball screw of an electromechanical brake comprising a ball screw nut disposed on a spindle, wherein the spindle includes complementary tracks formed on the spindle and the ball screw nut. The ball screw further includes a race that includes a plurality of ball pockets spaced apart from one another and a protruding section that includes a concave bearing surface, a ball housed between the concave bearing surface and an end section of a first spring element for a main load direction, and a second spring element for a return stroke direction, wherein the second spring element includes a second spring end section in contact with an opposite side of the bearing surface.

Abstract: A cage for rolling bodies of a rolling bearing, which has a first side ring, a second side ring axially spaced from the first side ring, and at least two webs, which connect the first side ring to the second side ring and among each other form a pocket for one of the rolling bodies. At least one of the webs has a first web part disposed at the first side ring and a second web part disposed at the second side ring, and a center web part offset with respect to the first and second web parts. The cage is configured such that it can withstand mechanical stresses via a support element which is provided and which supports the first web part and the second web part and connects the two side rings.
