2. Monolithic structure withstands extreme pressure; Fully threaded external housing facilitates installation and adjustment while maintaining superior heat dissipation.
3. High-hardness stainless steel spindle enhances impact resistance and corrosion resistance, ensuring reliable operation in harsh operating conditions.
4. Specialized oil-injection technology ensures consistent damping performance and operational stability.
5. Compact profile design with industry-leading energy absorption capacity.
6. Proprietary lubricant as damping medium delivers stable buffering performance across wide temperature ranges (-20°C to +80°C).
