how to calculate dynamic load of ball mill in Mexico
How to calculate linear bearing life
Dynamic load capacity is the load at which a linear guide will, with 90% certainty, achieve the targeted service life before fatigue (flaking) occurs on the rolling elements or raceways. The ISO 14728 Part 1 specification allows either 50,000 m or 100,000 m to be used as the targeted service life for dynamic load capacity.

How do bearing companies calculate their bearing's dynamic load …
Dynamic load ratings are determined by bearing geometry, number and size of balls, bearing pitch diameter, and ring and ball material. This load rating is used in conjunction with the actual applied radial load to calculate bearing fatigue life. The static load rating relates to limiting loads applied to non-rotating bearings.
