• Compact structure design using high-strength materials with special heat treatment and welding processes ensures exceptional fatigue life under high pressure and heavy loads
• Multi-channel sealing design guarantees stable operation of the sealing system
• Wide temperature resistance range (-25℃ to +120℃) with options for higher or lower temperature applications
• High load-bearing guide structure in the inner hole of the guide sleeve maximizes side load resistance
• Special surface treatment on piston rod ensures excellent wear resistance and corrosion resistance
• Working pressure, size specifications, installation methods, and other parameters can be fully customized to customer requirements

The hydraulic cylinder buffer system typically consists of a buffer plunger, buffer chamber, and orifice:

Buffer Plunger: 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: Positioned between the buffer chamber and working chamber, or on the buffer plunger. The size and number of throttle holes regulate the magnitude and effectiveness of the buffering force.
