Hydraulic cylinders that are used on construction equipment must be rugged and reliable. They will experience a lifetime exposed to heavy use in a harsh environment. Failure in service will result in costly downtime, project delays and maintenance headaches.
These cylinders must be designed to withstand the following:
Temperature Extremes -winter cold and summer heat.
Abrasives - dirt, grit and dust.
Corrosive Environments - rain and salt.
Work Load - heavy continual use.
Contamination - asphalt and cement splatter.
