Shock Absorber

NAK Shock Absorber Seals are specialty oil seals for use in the automotive shock absorber with double functions, to prevent the leakage of the dampening fluid / gas and to seal against external contaminants during the reciprocating motion of the shaft, which are critical requirements for the shock absorber in regard to its function and service life.


  • Resistant to high and low temperatures
  • Resistant to high pressures 
  • Work well under high surface velocity
  • Resistant to shock absorber fluid

NAK designs and manufactures seals in this category for automotive, motorcycle, bicycle, and many other industrial applications.
