ROLLING-CONTACT BEARING Russian patent published in 2008 - IPC F16C19/22 F16C33/34 F16C33/46 

FIELD: engineering industry; bearing industry.

SUBSTANCE: rolling-contact bearing includes rolling elements in form of rollers with cylindrical opening, where the separating element, being a spacer bar immovably fixed between two faces of the annular gaskets situated in parallel. Rollers are manufactured in a manner providing the opportunity of the elastic voluminal radial deformations in run of installation and under the functional stress. The width of at least one of the annular gaskets, corresponding to a half of the difference between its external and internal diameters, is greater or equal to the roller diameter decreased to the radial deformation value. At that, the rigidity of one of the annular gaskets in radial direction should exceed that of the rollers.

EFFECT: bearing life time increase.
