Abstract
A solid window cage for a cylindrical roller bearing is provided. The pockets for the cylindrical rollers are defined between two axially spaced end rings and by circumferentially spaced apart webs which join the end rings. On each web facing into each pocket, a respective roller holding ledge is developed. The ledge extends in the circumferential direction of the cage into the respective pocket for preventing the roller from falling radially from the pocket. The ledge has an axially central section which projects in the circumferential direction of the cage further into the pocket, and the sides of the ledge adjacent the central section gradually decrease in height in the circumferential direction of the cage toward the end rings, giving the ledge an either dome or trapezoidal shape. The cage has undercuts extending radially through the cage at the transitions between the end rings and the webs.
