Wearing ring
It has precise guidance function for running piston rod in the hydraulic tank and avoid crashing between metals. Compared with metallic wearing ring, non-metallic wearing ring has many advantages¡£
Advantages: 1.Long-lasting wearing character
2.Avoid crashing between metals.
3.Keep engineering flashing down.
4.More gap is permitted because of negative function between the wearing rings.
5.Simple structures and easy to installation.
6.Less maintaining fee so widely used.
Material: 1.PTFE
2.POM and nylon PA
3 .Urea-Formaldehyde Resin? plus intensified fibre

Calculation on cutting length
Center:
T-width of the wearing ring(mm) F-max load(N)
F-safety efficiency D-diameter of piston rod(mm)
Pr-maximum allowable radial load(N/mm2)
Sample£º
d=60mm F=40000N t=60¡æ
f=2 Pr=90N/mm2
T=14.8mm Choose the wearing belt (width 15) or 2 wearing belts (width 9.7 each) which is suggested to be used in order to max the width and ensure the safety.

Merit
1.advantage:1.Less friction£»
2.Working well when lubrication are non-used£»
3.could adapt to be used in multiple media£»
4.could take other hard object into it and reduce the efficiency of crashing£»
5.Long lasting wearing and widely used£»
6.No more restrictions in sizes and could be used in bigger diameter occasions¡£
