Hydraulic buffers offer smooth cushioning, stable performance, large capacity, no "rebound" effect, and easy adjustability. Their overall performance is far superior to that of other types of buffers.
Typically, a hydraulic buffer consists of a striking head, a return spring, a piston rod, and other components. Its working principle relies on the viscosity of the fluid to provide a damping effect. It can operate over a wide temperature range by utilizing the characteristics of the oil, maintaining appropriate viscosity. At the same time, hydraulic buffers have a simple structure and are easy to seal, which has made them increasingly popular among manufacturers.
Compared with ordinary hydraulic buffers, heavy‑duty hydraulic buffers can withstand greater impact forces. They generally use steel springs as return springs. When a mechanical system is subjected to repetitive impacts, using compressed gas as the return element not only enables the buffer to endure higher impact forces but also extends the buffer's service life and reduces maintenance requirements.
The heavy‑duty hydraulic buffers produced by CJAC feature large cylinder diameters, long stroke lengths, and high energy absorption capacity. They can also be customized according to different application conditions, adapting to various operating environments to meet diverse customer needs.
