Bearing Arrangement - an overview | ScienceDirect Topics
Thrust bearing, Fig 3.12A, composed of bearing balls supported in a ring, these can be used in low thrust appliions where there is relatively small axial load, but are susceptible to radial loads. Tapered roller thrust bearings, Fig 3.12B, consist of small tapered rollers arranged so that their axes all converge at a point on the axis of the bearing.

Magnetic Bearing | NASA Spinoff
Beginning in 1989, AVCON worked with Lewis to explore the possibilities of a magnetic bearing system for the turbopump of the Space Shuttle Main Engine. NASA decided to investigate magnetic bearings, which in theory-at that time-offered multiple advantages over conventional rolling element bearings.

27/9/2010· The ball bearings used in most electric motors are pre-greased, shielded ball bearings. Normal motor bearing operating temperatures range from 140°F (60°C) to 160°F (71°C). Overheating in electric motor bearings is generally lubricant-related.
Aerospace bearing - Wikipedia
Aerospace bearings are the bearings installed in aircraft and aerospace systems including commercial, private, military, or space appliions. Materials include M50 tool steel (AMS6491), carbon chrome steel (AMS6444), the corrosion resistant AMS5930, 440C stainless steel, silicon nitride (ceramic) and titanium carbide-coated 440C.
