FIELD: machine building.SUBSTANCE: rolling bearing comprises support surfaces of larger and smaller diameter, and rolling bodies arranged inside of them. Besides, inside of at least one support surface of larger diameter with the possibility of interaction there are at least two rolling bodies arranged with a gap. In the gap between them there are two rollers with a clearance, with the possibility of interaction by rolling bodies. Rollers mostly protrude at both sides from the support surface of the larger diameter and are placed by their journals inside of mostly two support surfaces of smaller diameter as capable of interaction with them. The bearing is made as capable of serial location of support surfaces of larger and smaller diameter with rolling bodies placed inside them in a row. Rollers are made as extended and stretch inside all support surfaces.EFFECT: elimination of sliding friction in a bearing, which makes it possible not to use lubricant in general in a device and use it under critical conditions of operation, when regular bearings break down The design makes it possible to use rolling bodies from friction and elastic materials, even rubber. |
