Hybrid bearings
Hybrid bearings have rings made of bearing steel and rolling elements made of bearing grade silicon nitride (Si 3 N 4) which make the bearings electrically insulating Silicon nitride rolling elements can extend bearing service life by offering enhanced bearing performance even
Bearings for high speed operations
To offset this reduction the raceways of a hybrid bearing could be made with closer conformities to obtain a larger contact area but this would then have a negative influence on the speed capability For high speed bearings the reduction in centrifugal loading will more than compensate for the lower dynamic load rating see figure 7

skf supplies bearings for zytek s hybrid-electric race car skf has been chosen by zytek engineering to supply customised and standard deep groove ball bearings to the electric motor generator unit and the intermediate shaft of the new ginetta-zytek gz09hs
Evaluating hybrid bearings for general applications
Hybrid precision bearings generate a much lower friction and thus operate at lower temperatures than steel bearings under very high speed conditions (nd m 1 million) This has been attributed to the smoother surface and the smaller contact ellipse of the silicon nitride balls which results in a lower spin-to-roll ratio for hybrid bearings
QIBR Single row hybrid deep groove ball bearing closure on
Hybrid bearings have a ring made of bearing steel and a rolling element made of bearing-quality silicon nitride (Si3N4) Hybrid bearings are not only excellent electrical insulators they are also approved for higher speeds and have significantly lower maintenance requirements than bearings manufactured entirely from steel

Hybrid bearings in oil
May 16 2002The studies showed that it was difficult to find a limiting dilution ratio for the hybrid bearings Finally in 1996 hybrid bearings were run in pure refrigerant and the bearings were in as-new condition at the end of the test This was a critical test result which opened up the possibility to use refrigerant as a lubricant for hybrid bearings

The progression of surface rolling contact fatigue damage
Dec 18 2015Rolling contact fatigue (RCF) is a typical failure mode in rolling bearings and similar types of machine components The fundamental work in RCF is due to Lundberg and Palmgren [1] [2] The Lundberg-Palmgren theory was mainly focused on subsurface rolling contact fatigue and it relies entirely on ideally smooth Hertzian stress calculations
