2. SGC series features a custom bidirectional piston seal design with integrated oil reservoir for compact dimensions and enhanced lubrication. (Note: SG series adopts dual Y-type unidirectional seals with compensation mechanism for extended service life and low actuation pressure);
3. SG series utilizes steel tube construction for superior impact resistance;
4. SGC series employs aluminum tube configuration with optional magnetic piston for sensor compatibility (magnetic option unavailable for SG series);
5. Precision-adjustable cushioned stroke control ensures smooth operation;
6. Comprehensive selection of cylinder sizes and mounting accessories available for system integration;
7. High-temperature resistant sealing materials enable operational range of 0-150°C.
