bearing cylindrical roller, especially to support rolls of rolling stands to cold in many cylinders.

摘要

A journal bearing with several rows of rollers, separated by one or more spacing rings, has an inner and an outer race defining between them an annular clearance which is laterally bounded by a first pair of annular disks fixedly secured to the inner race and a second pair of annular disks removably fastened to the outer race by a bayonet coupling. A spring-loaded bolt inserted in a bore on each end face of the outer race, between bayonet lugs thereof, snaps into a depression of the corresponding boundary disk when the latter has been rotated into its engaged position. A partly uncovered end of the bolt allows its repression by a suitable tool to release that disk for the purpose of disassembly.
