Oil-free bushing lifespan calculation
The life of oilless bushings depends on the amount of wear. The calculation of wear amount is very different due to surface pressure, sliding speed, movement pattern, lubrication conditions, surface roughness of matching shaft and other conditions.From the viewpoint that the wear amount is proportional to the load and sliding distance, the following formula is usually used to calculate the wear amount. Please consider it as the standard for selection.
Estimate wear(mm)W=K*1×p×v×T
Wear ratio(k):mm/(N/mm2·m/s·Hr)
Design surface pressure(p):N/mm2
Sliding speed(v):m/s
Friction time(T):Hr-hr
Roughly Standard for Friction Ratio
