ACD Series Hydraulic Buffer (Bidirectional Damping)

The ACD series adopts a double-acting cushioning structure with different damping effects at both ends. It is suitable for high-speed scenarios, widely used in robotic arms, eliminates equipment noise and vibration, and can greatly improve the operating speed of robotic arms.

AC-K Series Hydraulic Buffer

The AC-K series effectively absorbs vibration and noise generated by high-speed motion, converting kinetic energy into thermal energy and dissipating it into the air, thus enabling smooth and reliable stopping of objects in every operation. In the past, many manufacturers only used PU rubber and springs for cushioning to reduce costs, which often led to poor performance, persistent noise, stagnant efficiency, and premature wear and damage of mechanical equipment. Choosing CJAC hydraulic buffers can effectively eliminate the drawbacks caused by inadequate cushioning, improve mechanical efficiency, boost production capacity, and protect and extend the service life of machinery. Both AC-K and ACD are suitable for high-speed impact scenarios and the end of long-stroke moving devices, and are mostly applied to robotic arms.

AD-W Series Hydraulic Buffer (Adjustable Damping)

The AD-W series features a side-adjustable structure. When installation space is relatively limited and the viewing angle for adjustment is poor, all scales can be viewed simultaneously, allowing you to fine-tune the damping force as required and lock the setting.

HI Series Heavy-duty Hydraulic Buffer

HI series hydraulic buffers are designed for the safety of heavy mechanical equipment and are widely used in ports, railways, steel and other industries. They feature large bore diameter and high energy absorption, which can effectively reduce the moving load of heavy mechanical equipment. The HI series adopts a gas-liquid separation structure and uses nitrogen for return, with simple maintenance. Its working principle is: when the impact head is struck by external force, the piston rod moves downward to press hydraulic oil through the orifice, generating damping force. Meanwhile, the hydraulic oil compresses the nitrogen in the gas chamber. When the load is removed, the high-pressure nitrogen presses the hydraulic oil to push the piston upward, resetting the piston rod and completing one working cycle.

HD Series Heavy-duty Hydraulic Buffer

HD heavy-duty buffers provide a safe operating environment for large mechanical equipment. In compliance with industrial safety standards, CJAC has designed heavy-duty hydraulic buffers with large bore diameters, long strokes and high energy absorption capacity for various operating conditions, achieving stable linear deceleration of large mechanical equipment.

DL Series Hydraulic Buffer for Circuit Breakers

In high-voltage circuit breakers, hydraulic buffers are vital core components. During the opening and closing operations of the circuit breaker, the mechanism drives the moving end of the arc extinguishing chamber to the specified position. High-speed movement generates severe impact, and metal-to-metal impact inevitably causes rebound. The rebound reduces the contact gap distance, lowers the dielectric withstand voltage of the contact gap, and may lead to opening/closing failure in severe cases.

AC/AD Series Hydraulic Buffer for Stopper Cylinders

Hydraulic buffers for stopper cylinders are available in two structures: self-compensating and adjustable. They can be placed inside the stopper cylinder to deliver smooth deceleration and stopping for moving objects.

HR Series Precision Speed Stabilizer

The HR precision speed stabilizer can continuously and stably control the moving speed of objects for a long time, and adopts spring and pneumatic return actions respectively. To adapt to various special environments, in addition to the built-in dust-proof device inside the product, an external dust cover is also designed to ensure the service life and speed stabilization effect of the product. The HR speed stabilizer also uses special hydraulic oil, so that the propulsion speed will not vary due to temperature rise caused by moving loads. It is small in size, easy to install, and equipped with 30 scales for you to adjust and control the moving speed of objects.
