On many occasions, and the spherical bearing lead code meaning bearing hole size has a machine or device structure by specific defined. No matter the job life, static load safety coefficient and the economy are meet the requirements, finally chosen bearing the rest in size and structure before form, must pass dimension calculus. The operations including the actual load bearing with its load capacity are compared.

The static load of rolling bearing refers to the load bearing of the static after (no relative motion between inside and outside circle) or rotating speed is very low. Domestic bearing manufacturer code and international brand bearing 2010-11-29 10:18:32 code in this case, the calculus groove and rolling body excessive plastic deformation of the safety coefficient.

Bearing clearance choice CRT most by moving load bearing, inside and outside circle do relative motion, size calculus groove and check roller early fatigue damage safety coefficient.
Only in special cases, according to the DIN ISO 281 only to actual can achieve the working life of the name do life calculus. Sweden with Japanese seiko SKF group NSK bearing the strength of the company to pay attention to the economic performance of the competition for design as well as possible for the full use of the bearing capacity of the bearing. To think more fully utilize bearing, then choose the operations of bearing size accuracy is more important.
