FIELD: plastic working of metals, namely apparatuses for controlling efforts applied to pressure rollers, for example to backup rolls.
SUBSTANCE: journals of pressure rollers or backup rolls rest upon rolling or sliding bearing assemblies mounted in casing of bearing assembly support or in chock of rolls of rolling stand. Each journal has step resting upon radial bearing assembly whose casing is attached from outside to casing of bearing assembly support or to chock of backup rolls. Intermediate cylindrical body is arranged in casing of radial bearing assembly and it embraces casing of radial bearing assembly. Said intermediate cylindrical body is driven to motion from piston cylinder and it controls shifts of casing of radial bearing assembly in radial direction relative to axis of roll journal step.
EFFECT: possibility for quick accurate regulation of rolling efforts, enhanced strength of bearing assemblies, prevention of damages of peripheral surfaces of rollers.
