This series is known for its excellent environmental adaptability and maintenance convenience. The piston rod is equipped with a dual wiper seal, effectively preventing sand, dust, and contamination from entering and extending seal system life. The one-piece welded head design enhances overall rigidity. Internally, it uses low-friction, high-wear-resistant guide rings and seals, ensuring smooth operation even under extreme temperatures. The product undergoes rigorous durability testing, meeting the performance and quality requirements of major OEMs, and boasts high interchangeability and market prevalence.
The standard working pressure is 21-28 MPa, with a test pressure as high as 35 MPa. Bore sizes range from 30mm to 200mm,with rod diameter series validated for load matching by the industry. Various connection forms for both rod end and cap end are typically offered(e.g.,threaded, clevis with bushing).Standard strokes are customized according to host machine design. All products undergo full-load and full-stroke testing before leaving the factory to ensure reliable performance. Pressure test ports for troubleshooting can be provided.
Widely used in various types of mobile construction machinery as the core component generating linear force. In hydraulic excavators, they drive the boom, arm, and bucket. In loaders, they control lift arms and bucket tilt. In cranes, they are used for telescopic boom and outrigger cylinders. In agricultural machinery like harvesters and tractors, they perform lifting and steering functions. Their reliable performance ensures the continuous operation of these machines in harsh conditions like fields and construction sites.
