Hydraulic cylinder assemblies are critical components that enable the movement and function of excavators. Reliable, high-pressure cylinder assemblies are essential for achieving optimal performance, productivity and durability from your digging machine.

5 Types of Excavator Cylinder Assemblies

There are 5 key types of hydraulic cylinder assemblies used in excavators:

  • Xi lanh gầu – Actuate the lifting and tilting of the bucket. Subjected to high impact loads.
  • Xi lanh cánh tay – Provide extension and retraction of the arm assembly. Must withstand heavy loads.
  • Xi lanh cần cẩu – Control the raising and lowering of the boom. Experience high resistance.
  • Swing cylinders -Rotate the upper structure, requiring high pressure and stability.
  • Stick cylinders (on larger excavators) – Actuate the stick that connects the arm and bucket.

Factors To Consider For Excavator Hydraulic Cylinder Assemblies

When selecting or replacing cylinder assemblies for your excavator, consider:

  • Kích thước lỗ khoan và chiều dài hành trình – Must precisely match the application requirements.
  • Đánh giá áp suất – Higher pressure ratings needed to handle tough excavator work.
  • Rod typeSolid rod preferred for heavy-duty excavator applications.
  • Con dấu – Effective seals are critical to keep out contamination and retain lubricant.
  • CertificationsMeet applicable industry standards for safety and reliability.
  • Vật chất – Steel tubing and rod standard, with chrome plating for corrosion resistance.

Options For Excavator Cylinder Assemblies

You have several options when procuring cylinder assemblies for your excavator:

  • Genuine OEMDesigned specifically for the machine with a perfect fit and durability.
  • Certified equivalentsManufactured to meet or exceed specs of OEM cylinders at lower cost.
  • AftermarketMore affordable initially but often have shorter life spans, increasing total costs.
