During long-term operation, pneumatic cylinder seal kits constantly come into contact with and rub against the cylinder wall and piston surface. If lubrication is insufficient or the surface roughness is high, the wear rate of the seals will accelerate. Ultimately leading to a drop in internal cylinder pressure.

During long-term operation, the piston repeatedly moves inside the cylinder. The seals need to maintain contact with the cylinder surface to achieve a sealing function. With increased use, the sealing rings in pneumatic cylinder seal kits may gradually wear down, leading to a decrease in sealing performance.

Under normal design and installation conditions, pneumatic cylinder seal kits should be stably fixed within the sealing groove. If they detach, it usually indicates a problem in some aspect. Common causes include improper installation, an inadequate sealing groove design, material aging, and abnormal pressure.

Pneumatic cylinder seal kits are key components in the pneumatic cylinder sealing system. They are typically installed near the piston or piston rod to prevent compressed air leakage and maintain stable internal cylinder pressure.

Among various sealing materials, nitrile rubber (NBR) is one of the most common and widely used materials in pneumatic cylinder seal kits. NBR is widely used in pneumatic systems due to its good oil resistance, wear resistance, and moderate elasticity.

PTFE materials have excellent heat resistance, and some high-performance pneumatic cylinder seal kits can operate stably in environments approaching 200℃. Therefore, overall, the heat resistance temperature of high-performance pneumatic cylinder seal kits can reach approximately 200℃.
