2.Hardness
The hardness for Rubber U Ring is relative with the working pressure
Relationship of hardness & working pressure:
3.Working condition
It`s important that keep the clean of working medium. Oil aging or pollution could make the components fail, accelerate the aging and abrasion of oil seal. Moreover the dirt could lead seal failure. Therefore, workers must be check the quality and cleanliness of oil regularly. Sealing parts are burn out by high temperature which caused by residual air compressed in oil of cylinder. In order to avoid it, in the initial operation of hydraulic system, exhaust air disposal is needed, hydraulic cylinder also should be work several minutes firstly under low pressure and slow running. Work normally after confirming that all of the air have be removed.
