Product Description

Gap sealing is a special sealing method in Large Hydraulic Cylinders, which is completely different from the commonly used rubber or polyurethane seals.

The commonly used gap seal for metallurgical Hydraulic Cylinder has the following advantages:

1. Extremely low friction: Due to the lack of direct contact and compression between rubber seals and metal surfaces, the starting friction is small, the movement is smooth, and there is no "crawling" phenomenon, making it very suitable for low-speed and micro motion control.

2. Extremely long lifespan: Without issues such as wear, aging, or extrusion of seals, theoretically the lifespan is semi permanent (as long as the gap is not damaged).

3. Strong high temperature resistance: Its performance is not limited by temperature, as long as the material itself can withstand it, it is suitable for high temperature applications.

4. Good pollution resistance: Small particle pollutants may be carried away by the oil, unlike soft seals that are easily scratched by particles and fail.

Gap sealing is a high-end sealing form based on precision machining, whose core is to exchange controllable small leaks for zero friction, long life, and high responsiveness

In ordinary Industrial Hydraulic oil Cylinders, the more common form is the combination of contact seals or gap seals with sealing rings.
