An Overview of Bearing Vibration Analysis

A common approach is to mount the bearing on a quiet running spindle and measure the radial velocity at a point on the bearing’s outer ring in three frequency bands, 50-300, 300-1800 and 1800-10000Hz. The bearing must meet RMS velocity limits in all three frequency bands.

Bearing (mechanical) - Wikipedia

A bearing is a machine element that constrains relative motion to only the desired motion, and reduces friction between moving parts.The design of the bearing may, for example, provide for free linear movement of the moving part or for free rotation around a fixed axis; or, it may prevent a motion by controlling the vectors of normal forces that bear on the moving parts.

Let''s talk bearings. : rollerderby

There can be a big difference. I''ve seen skaters gain 2-3 laps on their 27/5 just by replacing crappy old half-seized bearings. I''d say over $100/16-pack you''ll start seeing diminishing returns, but you can tell the difference between rolling $35 bearings and $120 bearings (at least on a decent floor, and of course a good clean set of $35 bearings will out-perform a $120 set full of …
