Abstract
A rolling bearing includes an outer ring having an outer surface configured to be fitted into a first component, an inner ring having an inner surface configured to be fitted onto a second component, at least one rolling element arranged between the outer ring and the inner ring, and an antimony-free composite coating comprising a binder and a solid lubricant on the outer surface of the outer ring and/or the inner surface of the inner ring.
Claims21
A rolling bearing comprising:
- an outer ring having an outer surface configured to be fitted into a first component,
- an inner ring having an inner surface configured to be fitted onto a second component,
- at least one rolling element arranged between the outer ring and the inner ring, and
- an antimony-free composite coating on the outer surface of the outer ring and/or the inner surface of the inner ring,
- wherein:
- the antimony-free composite coating comprises a binder and a solid lubricant, and
- the composite coating has a porosity of 2 to 50 vol % and a pore size of 2 to 50 μm.
A rolling bearing comprising:
- an outer ring having an outer surface configured to be fitted into a first component,
- an inner ring having an inner surface configured to be fitted onto a second component,
- at least one rolling element arranged between the outer ring and the inner ring, and
- an antimony-free composite coating on the outer surface of the outer ring and/or the inner surface of the inner ring,
- wherein:
- the antimony-free composite coating comprises a binder and a solid lubricant, and
- the composite coating has a dielectric strength greater than 10 kV/mm and a dielectric constant of lower than 6.
A rolling bearing comprising:
- an outer ring having an outer surface configured to be fitted into a first component,
- an inner ring having an inner surface configured to be fitted onto a second component,
- at least one rolling element arranged between the outer ring and the inner ring, and
- an antimony-free composite coating on the outer surface of the outer ring and/or the inner surface of the inner ring,
- wherein:
- the antimony-free composite coating comprises a binder and a solid lubricant, and
- the solid lubricant is between 2 to 20 wt % of the composite coating.
