Construction Equipment Hydraulic Cylinders
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.
1.Rod seal:superior quality named-brand seals improve a longer life and seal effect polyurethane U-packing rod seals/buffer seals · bonded-to-metal wiper seals custom seals available
2.:Skived&burnished or vertical honing tube assures the concentricity and straightness
3.Bushing:Hardened steel bushing or copper bushing
4.Eye:All eyes are made of forged high strenght steel improve cylinder not only in appearance but in mechanical performance
5.Rod:Induction hardened prior to chrome plating enhances the surface hardness,enhanced chrome plating improve corrosion resistence and anti-scratch performance
6.Piston:High pressure piston sealing material:teflon or nylon seals.High precision machining maximize the consistency of parts.
7.Cap:All caps are made of forged high strength steel
