When pressing the oil-free bushing, use a vise or punch to press it in quietly. In order to facilitate the press-in, it is recommended to chamfer the end of the inner diameter of the fixed seat, apply a small amount of lubricating oil to the inner diameter of the fixed seat and the outer diameter of the bushing.
Anti-rotation screw/bonding
Note that when the oil-free bushing is prevented from falling off and turning, it is recommended to use the following methods depending on the conditions of use and the environment.
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
Lubrication condition
mm/(N/mm2·m/s·Hr)
mm/(kgm/cm2·m/min·Hr)
No lubrication
3×10-3~6×10-4
1~5×10-6
Regular lubrication
3×10-4~6×10-5
1~5×10-7
Grease
3×10-5~6×10-6
1~5×10-8
