A radial cage in which roll forming is carried out in such a manner that straight side sections of all axial crossbars continue to have at least approximately a material thickness of a starting material for the radial cage, while side rings of the radial cage and axial center sections of the axial crossbars are implemented by rolling down during roll forming to each have material thicknesses that are smaller than the material thickness of the straight side sections and that reduce their centrifugal mass.

Radial cage for cylindrical roller bodies

A radial cage in which side rings have a material thickness of a starting material for the radial cage, straight side sections of each axial crossbar are implemented with a greater material thickness that increases their strength, and an axial center section of each axial crossbar is implemented with a smaller material thickness than the material thickness of the side rings, thus reducing centrifugal mass.

A bushing-type roller overrunning dutch comprising an inner and/or outer ring (), clamping ramps () adapted to the needles or rollers (), a cage (), pressure springs () for the needles or rollers (), a bushing () with integrally formed clamping ramps (), and a solid inner or outer ring () in or on which the bushing () is fixed.

A sprag for a sprag-type freewheel clutch having a profile comprised of multiple profile sections, the sprag having at least the profile sections of an inner engagement curve, an outer engagement curve and a first and a second lateral curve, wherein the outer and inner engagement curves each form a component of a logarithmic spiral.

A thrust washer () for planet gears () of a planetary gearbox is provided that is made form a tempered, cold rolled strip having a flatness less than or equal to 0.03 mm, and a hardness ranging from 370 to 580 HV. The thrust washer () can be produced in a particularly cost effective manner by making it from an appropriate initial stock having the desired final properties.

A method of making a cage whose crossbars ( ) connecting the side rings ( ) are profiled whereby the rolling elements ( ) are retained individually on both sides of the pitch circle by retaining edges ( ) extending parallel to the axis of the rolling elements wherein by an additional shaping by material displacement after the punching out of the pockets ( ), parallel opposing guide surfaces ( ) for the rolling elements ( ) are formed within the pitch circle between the retaining edges ( of the pockets ( ) and the retaining edges ( ) on both sides of the pitch circle are dimensioned so that the distance between them in the peripheral direction is only slightly smaller than the diameter of the rolling elements ( ) wherein a defined contact of the rolling elements ( ) with the cage is achieved due to the stamp guide surfaces ( ) so that the mechanical loading of the cage is insignificant.
