1. Manufactured in compliance with enterprise standards;
2. Features riveted integration between cylinder barrel/rear cover and piston/piston rod for compact reliability;
3. Barrel bore undergoes precision roller burnishing followed by hard anodizing for superior wear resistance and extended service life;
4. Patented asymmetric bidirectional piston sealing design with integrated lubrication reservoirs ensures space efficiency;
5. Optimized footprint minimizes installation spatial requirements;
6. Pre-machined sensor mounting grooves around barrel periphery enable tool-free sensor installation;
7. Multiple configurations available to accommodate specific application requirements.
