1. The temperature with friction, of a kind of seal material used the highest temperature and minimum temperature it is difficult to describe, because this is the result of a series of comprehensive influence.For the working temperature of piston and piston rod is different, to make a difference to their choice.Another is seal product surface roughness, surface features, pressure, medium, temperature, seal material, seal type and speed of movement these are the factors that affect the seals.
2. Surface treatment, experience has shown that the features on the surface of a cylinder piston and piston rod seal life has very big effect.Surface roughness RA value to define surface features, RA is the arithmetic mean surface shape deviates from the center line of absolute value.But some numerical cannot fully shows the effect of surface condition of seal, this is because even in the same roughness, different surface shape feature can lead to different to seal the wear degree of the seals.
