FAG Bearings can reach the number of life Lna, Lhna coefficient a23 and time: 2010-09-15 14:03:27 Source: Author: bearing supplier Click: 1 .1) life Lna number reachable, Lhna
Lna=a1xa23xL[106 rpm] and Lhna[h]
In the formula a1------ power loss coefficient a23 ------ power loss coefficient with respect to the coefficients a1 and a3 in DINA ISO 281, think about their contact with each other; so combine them into a23.
A23= a2xa3
L radical extra life [106 rpm]
Lh radical extra lifespan [h]
.2) Coefficient a23
.2) Coefficient a23
The coefficient a23 is used to calculate the reachable lifespan Lna or Lhna; it is obtained by the following formula:
A23= a23âˆ xs
In the formula a23âˆ xs fundamental value S cleanliness coefficient coefficient a23âˆ xs The influence of factors such as material, bearing type, load, smoothness and cleanliness. Regarding higher or lower cleanliness; take s>1 or s< 1.
