Buffer plunger: Generally installed at the end of the piston rod or cylinder head. When the cylinder reaches the end of its stroke, the buffer plunger first enters the buffer chamber.

Buffer chamber: A specially designed space connected to the working chamber. When the buffer plunger enters, it compresses the oil inside, generating a buffering force.

Throttle hole: Set between the buffer chamber and working chamber, or on the buffer plunger. The size and number of throttle holes adjust the magnitude and effectiveness of the buffering force.

High Power Density

Provides greater force within smaller volumes by increasing pressure without increasing physical size.

High Reliability

No mechanical connections mean minimal friction or wear, ensuring high operational reliability and long service life.

High Precision Control

Achieves precise motion control by adjusting pressure and flow for accurate position and speed management.

Stable Motion

Smooth movement without impact or vibration through fluid force transmission characteristics.
