HBY - The U-cup has an asymmetrical profile of the sealing lip and has a reduced pressure sealing edge with reduced pressure capability to prevent internal pressure entrainment when used in a tandem sealing system. The rod seal is designed to absorb shock pressure and pressure fluctuations under high load conditions, thereby extending the life of the series seal.

Combined with a rod seal, it absorbs shock and impact pressure under heavy load to separate high temperature fluids and increase the life of the sealing element. Suitable for motorized shovel, wheel loader, bulldozer, truck crane, wheeled crane, dump truck, etc. For design and application, DSH Seals’ HBY are designed according to NOK's HBY, DZ's D-10 series.


Advantages

  • No adhesion to the sliding surface.

  • Relieve any pressure build-up that may occur.

  • Excellent abrasion and wear resistance.

Material descriptionnbr / fkm rubber,POM, and so on
Available ColorYelllow, black and so on
Material StrengthThis is used in combination with rod packing to absorb the impact and fluctuating pressures at high load, to isolate high temperature fluids, and to improve the durability of the packing. It has a special shaped slit at the sliding lip that can leak back pressure, and eliminates the pressure between the rod packing and the buffer ring. Used with general petroleum hydraulic fluid oil.
