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:
- Bucket cylinders – Actuate the lifting and tilting of the bucket. Subjected to high impact loads.
- Arm cylinders – Provide extension and retraction of the arm assembly. Must withstand heavy loads.
- Boom cylinders – 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:
- Bore size and stroke length – Must precisely match the application requirements.
- Basınç derecesi – Higher pressure ratings needed to handle tough excavator work.
- Rod type – Solid rod preferred for heavy-duty excavator applications.
- Mühürler – Effective seals are critical to keep out contamination and retain lubricant.
- Certifications – Meet applicable industry standards for safety and reliability.
- Malzeme – 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 OEM – Designed specifically for the machine with a perfect fit and durability.
- Certified equivalents – Manufactured to meet or exceed specs of OEM cylinders at lower cost.
- Aftermarket – More affordable initially but often have shorter life spans, increasing total costs.
