High Quality Boom Hydraulic Cylinder Seal Kit Used Excavator Sany Sy135

Before seals can be selected certain application parameters and information should be collected. The following most common application considerations are nearly always required when selecting hydraulic seals:

Fluid pressure range,
the range of operating fluid system pressure, as well as frequency and severity of pressure peaks
Temperature range,
the range of the fluid and cylinder assembly, both when operating and at rest
Speed,
the stroking speed of the reciprocating piston rod
Fluid media,
the type and viscosity of fluid used in the system
Hardware dimensions,
the rod and bore diameters, seal groove dimensions and gaps (if already specified), cylinder overall length and stroke length as well as surface finish specifications (if already specified)
Application of the cylinder,
the type of equipment the cylinder will be used on and how the cylinder will operate in the equipment as well as installation, duty cycles and environmental factors (external temperature, contaminants)
