Lubrication-free roller bearing for high-temperature operation and rolls for continuous casting machines incorporating these roller bearings

摘要

The invention relates to a roller bearing which can operate without lubrication in the high-temperature range and has an outer race (6), an inner race (5), a roller cage (7) between these two races and two lateral rings (9, 10) which hold the roller cage in its position. ??According to the invention, the outer race (6) and the inner race (5) consist of an elastically deformable material and have a slot (11, 12) which extends from one end of the race to the other. ??These bearings are suitable for fitting to rolls for continuous casting machines.
