High Pressure Resistant Hydraulic Oil Cylinder for Small Medium Digger Excavator Parts
High Pressure Resistant Hydraulic Oil Cylinder for Small Medium Digger Excavator Parts
Excavator Hydraulic Cylinders Introduction
This hydraulic cylinder is specially designed for small and medium-sized excavators, featuring a compact and reasonable structure, high-strength alloy material, and hard chrome-plated piston rod with excellent wear resistance, pressure resistance and corrosion resistance. Equipped with a high-performance sealing system, it effectively prevents oil leakage, ensures stable and smooth operation under long-term heavy-load working conditions, and delivers strong power output and reliable action response. With high machining precision, good interchangeability and long service life, it can perfectly replace original parts, greatly improving the working efficiency and durability of excavators, and is an ideal choice for engineering construction, rural engineering, municipal construction and other working scenarios.
Excavator hydraulic cylinders are our specialty. We can supply hydraulic cylinders for various brands of excavators without affecting the normal operation of the machinery. If customers have additional requirements, we have professional technicians who can modify the cylinders according to their needs and propose suitable solutions.
Hebei Runhe Hydraulic Machinery Co., Ltd. has over 12 years of experience in the hydraulic industry, serving leading domestic OEM manufacturers. We mainly sell hydraulic gear pumps, hydraulic cylinders, hydraulic gear motors, and accessories, with clients from multiple countries worldwide, including Russia, Singapore, and Kosovo.

Excavator Hydraulic Cylinders Operation Method
- Pre-operation inspection: Check the piston rod (no scratches/rust), sealing system (no oil leakage), and hydraulic oil (meets requirements); stop if any abnormality is found.
- Startup operation: Operate the control lever gently to avoid sudden acceleration/stop; observe operation to prevent component interference or collision.
- In-operation control: Keep pressure and speed within rated range; avoid overloading. Clean the piston rod regularly under harsh working conditions.
- Shutdown operation: Retract the cylinder, cut off power, clean the cylinder, and apply lubricating oil. Drain oil and seal cylinder port for long-term shutdown.
- Maintenance note: Do not disassemble the cylinder without permission; professional technicians shall handle maintenance/replacement.
