1. The maximum permissible PV.
PV is the numerical value multiplying pressure per square measure (Kgf/cm2) by moving speed-per minute (v
cm/min), and it is important factor in selecting bearing. The numerical PV value of using condition should be
calculated accurately and not exceed the maximum permissible numerical value.

Durability of bearing depends on degree of abrasion. A degree of abrasion is decided by the size of bearing
and the condition of use, and it is connected diretly with durability of rearing. The reason to incrase abrasion
