Bearing rating life | SKF

When you want to avoid fatigue failures of the bearing before your appliion reaches its desired lifetime, you can use a statistical approach to determine the bearing size. The rating life L 10 is the fatigue life that 90% of a sufficiently large group of identical bearings operating under identical conditions can be expected to attain or exceed.

Spindle Speed - an overview | ScienceDirect Topics

This means that for low spindle speeds, the s of stability are not very high and are localized close to each other. But as the spindle speed approaches the values of n =0.5 f n / m (and mainly n = f n / m ), which denotes one wave between the subsequent teeth, substantial increase of the stability may be achieved by exact selection of the right rotational speed.

Spindle (tool) - Wikipedia

In machine tools, a spindle is a rotating axis of the machine, which often has a shaft at its heart. The shaft itself is called a spindle, but also, in shop-floor practice, the word often is used metonymically to refer to the entire rotary unit, including not only the shaft itself, but its bearings and anything attached to it (chuck, etc.).
