ISO9001 Standard Hydraulic Cylinders for Excavators – Arm, Bucket, Boom – Available for Sale
Construction equipment hydraulic cylinders must be built to last. They are exposed to extreme conditions, including high temperatures, dirt, and moisture, which can lead to failures if not properly designed. Our hydraulic cylinders are engineered to withstand these challenges, ensuring long-term performance and reliability.
Key Features of Our Hydraulic Cylinders:
1. **Rod Seal**: High-quality branded seals such as polyurethane U-packing and buffer seals are used for improved durability and sealing performance. Custom options are available.
2. **Tube Surface**: Skived and burnished or vertical honing process ensures concentricity and straightness for smooth operation.
3. **Bushing**: Hardened steel or copper bushings for enhanced strength and wear resistance.
4. **Eye**: Forged high-strength steel eyes for better mechanical performance and aesthetics.
5. **Rod**: Induction hardened before chrome plating increases surface hardness, while advanced chrome plating improves corrosion and scratch resistance.
6. **Piston**: Uses high-pressure Teflon or nylon seals with precision machining to ensure consistent quality.
7. **Cap**: Forged high-strength steel caps for structural integrity.
Our manufacturing technology includes:
- Skive Roller Burnishing Machines
- Vertical Honing Machines
- Machining Centers
- CNC Lathes
- Automatic Welding Machines
- Grinders and Polishing Machines
- Cylinder Assembly and Test Benches
- Spray Rooms
Production Process:
Materials → Tempering → Turning → High-Frequency Quenching → Grinding → Chrome Plating → Final Inspection
