MBA Piston Rod Seal

The MBA piston rod seal is an improved lip seal that combines the benefits of a highly elastic O-ring and wear-resistant lip material. The O-ring in the oil groove ensures proper pre-compression under low pressure or vacuum, maintaining good sealing performance. Even with wear, it keeps the necessary pre-compression. As system pressure increases, the O-ring deforms and presses the sealing lip tightly around the piston rod, ensuring excellent sealing. It is mainly used in hydraulic systems like plungers, piston rods, telescopic cylinders, air drills, forging machines, and walking equipment.
