ROLLING BEARING Russian patent published in 2007 - IPC F16C19/54 F16C33/34 

FIELD: mechanical engineering.

SUBSTANCE: rolling bearing comprises two-step rollers. The greater step rolls the way in the outer race of the bearing, and the smaller step rolls the way in the inner race of the bearing with a constant speed of rotation. The greater step of the roller is shaped into a barrel and is in a contact with the way in the outer race, and rollers are provided with opening that receives the axle mounted with a spaced relation and two built-in radial-thrust rolling bearings. Two disks play a role of separators and are not in a contact neither with the rollers or races of the main bearing . The transmission ration between the inner race and separator is equal to two when the outer race is unmovable.

EFFECT: expanded functional capabilities and prolonged service life.
