Technical Information: Ball bearing types, selection factors, and bearing …
Ball Bearings. There are several types of ball bearings that fit specific needs. The deep-groove ball bearing, Figure 2 (a), is the most versatile. Radial loads and thrust-load capacities may be approximately equal in this bearing. When it has the proper separator, it is very good for high-speed operation.
Speed limitations | SKF
The ISO standard, established for oil lubriion, is also valid for grease lubriion, provided a lithium based grease with mineral base oil having a viscosity between 100 and 200 mm²/s is used. Grease lubried bearings may however undergo a temperature during initial start-up, requiring a running-in period before they reach their steady-state operating temperature.

Oil&Gas - Centrifugal compressor - PetroWiki
1/6/2015· In a centrifugal compressor, energy is transferred from a set of rotating impeller blades to the gas. The designation “centrifugal” implies that the gas flow is radial, and the energy transfer is caused from a change in the centrifugal forces acting on the gas. Centrifugal compressors deliver high flow capacity per unit of installed space
