Limit speeds for bearing arrangements. If the spindle bearings are arranged in a rigid pre-stressed O-, X or tandem arrangement, the limit speeds of the single bearings shown in the bearing charts is reduced. For this purpose, a reduction factor f r is introduced which is defined according to bearing arrangement in the following table.
Get PriceIn this bearing arrangement, the contact lines are arranged in parallel. The axial load capacity is twice that of a single bearing, but only in one direction. That is why this bearing pair must be adjusted against another bearing or bearing pair. Universal Design (U) Universal bearings can be paired in any arrangement listed above.

Get PriceHigh-speed spindle systems typically employ angular contact ball bearings, which can resist both axial and radial loading, and exhibit high precision and durability. We investigated the effects of the arrangement of the angular contact ball bearings on the dynamics of high-speed spindle systems. The spindle dynamics were studied with a number of spindle-bearing models, and the location of the ...
Get PriceThe bearing arrangement for a rotating component, e.g., a shaft, generally requires two bearings to support and locate the component radially and axially relative to the stationary part of the machine. Depending on the application, load, running accuracy and cost the following approaches can be considered: • Locating and non-locating bearing arrangements.
