Design
- Equipped with a spherical saddle,it effectively enhances the anti-overload capability of the hydraulic cylinder.
- Dust seal, preventing external impurities from entering the interior of the cylinder and causing contamination or damage.
- The exhaust port expels air,preventing air resistance from causing jerky motion and noise,and ensuring stable operation of the hydraulic system.
- Powerful spring for rapid return stroke.
- The Swedish CEJN coupler and dust cap ensure safety throughout.
- Stop ring for absorbing overload and preventing piston overtravel.
- Dust seal, preventing external impurities from entering the interior of the cylinder and causing contamination or damage.
- High-pressure seal to achieve zero internal leakage in the hydraulic system, reducing wear and extending service life.
