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.

ExcavatorHydraulic 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.
