The seal of a Piston Rod Chrome Bar plays a challenging part among hydraulic components. Although possibly the cheapest, it is greatly expected to protect the hydraulic oil in the cylinder under a range of high temperature and pressure, stand with massive impact of pressure and pulsation, and block pollutant from entering the cylinder system. Once the seal of a piston rod is damaged, the leakage of hydraulic oil must be high cautioned and treated. To replace the broken one, it will spend much time and labor except for loss by necessary shutdown, in view of which it’s rather costly a job.
Pollution is usually the main cause of premature failure of a seal. The oil film formed on the piston rod can lubricate the seal and extend its lifespan. On the other hand, however, it absorbs dirt which adheres on the rod. When the rod draws back, the dirt can slide over the seal, leaving possible tiny damages. As a result, the perfectness of the seal becomes a care that must be highest taken while the measure to realize it is to keep pollutant away from the rod.
