2. Riveted construction between cylinder body & rear cover, piston & piston rod ensures compactness and reliability;
3. Cylinder bore undergoes roller burnishing followed by hard anodizing treatment for enhanced wear resistance and durability;
4. Asymmetric bidirectional sealing structure on piston features compact dimensions and incorporates an integrated oil reservoir for lubrication retention;
5. Space-optimized design maximizes installation efficiency in confined spaces;
6. Perimeter sensor groove design facilitates straightforward sensor mounting;
7. Available in multiple configurations to accommodate diverse application requirements.
