## **Product Overview**
The excavator head swing cylinder is a key actuating component specifically designed for hydraulic excavators, used to achieve the left and right swinging function of the excavator's working device. This product is made of high-strength materials and features an optimized hydraulic design, ensuring stable swinging performance and an extremely long service life under various harsh working conditions.
## **Core Features**
### 1. High Torque Output Design
- Utilizes a symmetrical layout of two oil cylinders, with the maximum output torque reaching 8000 - 15000 Nm
- Optimizes the lever ratio design to enhance energy conversion efficiency
### 2. Exceptional Durability
- The cylinder is precisely honed from 45# steel, with a surface hardness of over HRC50
- The piston rod is plated with hard chromium (thickness ranging from 0.05 to 0.08mm), providing excellent wear resistance and corrosion resistance
- Imported brand seals (Parker/Merkel) can withstand high pressure up to 35MPa
### 3. Precise Control Performance
- Built-in buffer device, swing angle control accuracy ±1°
- Optional displacement sensor for achieving closed-loop control
### 4. Intelligent Protection Function
- Integrated overload protection valve to prevent accidental impact from causing damage
- Built-in temperature sensor (optional), for real-time monitoring of oil temperature
