BEARING UNIT Russian patent published in 2006 - IPC F16C19/00 F16C33/58 

FIELD: mechanical engineering.

SUBSTANCE: invention can be used in machines and mechanisms. Proposed bearing unit has shaft journal, housing and antifriction bearing installed on shaft or in housing with interference, at least one race of which is furnished with device to release solids of revolution from working load in form of local change of curvature of race seat surface which, for outer race, is 1/R₁<1/R₀, and for inner race is 1/r₁>1/r₀ where R₁ and r₁ is radius of seat surface of corresponding bearing race in place of change of curvature and R₀ and r₀ is radius of seat of corresponding race of standard bearing.

EFFECT: provision of guaranteed relief of solids of revolution from working load, increased service life of bearing.
