Product Advantages
1. Original Genuine, Left Boom Specialized
Original Sany factory part, material code SSY005163379, 100% matches SY365H left boom cylinder and main valve interfaces, direct replacement.
2. High-Pressure Explosion-Proof, Vibration and Impact Resistant
Seamless steel pipe + high-pressure welding, pressure-resistant up to 343 bar; fatigue-resistant, resonance-resistant, explosion-proof, suitable for mining heavy-duty high-frequency working conditions.
3. Reliable Sealing, Leak and Rust Prevention
Original factory flange + imported O-rings, no leakage; internal and external rust prevention treatment, oil-resistant and aging-resistant, extending service life.
4. Precise Forming, Easy Installation
Original factory bending + laser drilling, precise routing and fixing points, avoiding interference; built-in vibration damper clamp, reducing vibration wear.
Installation Notes
- Corresponds to the left boom cylinder (original Sany SY365H).
- Clean the flange surface before installation; O-rings must be replaced with new ones.
- Secure the fixing clips at the original factory positions to avoid friction.
- Pressure test: Maintain 34.3 MPa for 5 minutes, no leakage is qualified.
