2. Features rivet-fastened barrel/rear cover assembly and piston/rod integration for structural integrity;
3. Barrel bore undergoes precision roller burnishing followed by hard-anodized surface treatment, ensuring superior wear resistance and operational longevity;
4. Asymmetric dual-lip piston seal configuration with integrated lubrication pockets optimizes compactness while maintaining sealing reliability;
5. Ultra-slim profile design minimizes spatial footprint for constrained installations;
6. Machined sensor grooves along barrel periphery enable simplified proximity switch integration;
7. Multiple mounting variants and stroke configurations available for application versatility.
