WebDynamic 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. WebThurman methods were selected for unit side resistance and end bearing in coarse-grained soil. Results The researchers achieved the following results: • DRIVEN exhibits a mild tendency to overestimate the length of pile penetration needed to reach capacity as determined with Gates. The tendency to overestimate length is most significant for the
