FAG BEARINGS PDF

X-life ultra Bearings X-life ultra bearings were designed for maximum demands on speed-ability and load. They are hybrid bearings with rolling bearing rings made of Cronidur 30, a high nitro-gen stainless steel. Compared to the conventional rolling bearing steel 100Cr6, Cronidur 30 exhibits a substantially finer structure, thus ensuring cooler

Bearing selection and life calculation - Kraśnik

Bearing failures due to fatigue undergo the law of statistic. That is why during bearing life calculation the probability of failure is taken into consideration In general, bearing life is calculated with 10% probability of failure, i.e. for reliability equal to 90%; then the reliability coefficient is equal 1.

Ball vs. Sleeve A Comparison in Bearing Performance

Sealed-for-life ball bearing systems use thicker lubricants that have more additives, and are less subject to evaporation. While the lubricants within sleeve bearing fans have a greater concentration of oil, the sleeve bearings’ bushings can only hold a fixed amount of lubricant. Since there is no periodic recharging of the oil, the

loads act on a bearing at the same time, the hypothetical load acting on the center of the bearing which gives the bearings the same life as if they had only a radial load or only an axial load is called the dynamic equivalent load. For radial bearings, this load is expressed as pure radial load and is called the dynamic equivalent radial load.
