0 Using extruded high-quality aluminum alloy cylinders, the inner surface of the cylinder is finely ground and finished. The internal and external surfaces of the cylinder are both hard anodized. Advanced anti-corrosion technology is used inside and outside, and the friction coefficient is low. Higher corrosion resistance. Longer life, stronger corrosion resistance.

O Adopts rack and pinion double-piston design, compact structure, modern shape, symmetrical installation position, easy to change the output shaft steering, long service life, smooth and rapid movement, composite bearing and guide ring on the back of piston rack, precise movement, friction The coefficient is small and the service life is longer.

0 The combination of preloaded safety spring packs makes it easy to safely install or increase or decrease the number of springs during assembly or use.
