    Product Description

  • Polyacrylate (Lip code: N) are well suited for use with extreme pressure (EP) lubricants and have higher resistance to oxidation and ozone than nitrile.
  • Resistant to sulphur commonly used as a grease additive.
  • Polyacrylate elastomers have good compatibility with higher temperatures up to 149°C (300°F), and even to 177°C (350°F) with some fluids.
  • They should not be used alongside water or other aqueous solutions.
  • Does not perform at temperatures below -40°C (-40°F)
  • Polyacrylates are not recommended for dry running applications.

  • Unitized seals spin on their own inner, wearable, elements, not your expensive axle shaft. They sacrifice their inner components so your axles stay clean and smooth.
  • The inner diameter of the seal seats snuggly on the axle and rotates with it, not cutting into it with road grime and other contaminants that would normaly augur in and mix with the bearing grease resultantly cutting into the axle shaft.
  • Unitized oil seals have shown to be more fuel efficient than traditional "heavy garter spring on metal wear sleeve" sealing solutions from the past.
  • Please note special tooling is required to properly install Unitized Oil Seals as they are easily damaged upon installation if they are mistruck during installation.

  • Please note that not all product images are representative of the item being shown but are similar in appearance. Please refer to the seals technical specifications sheet provided in the image carousel for absolute confirmation before ordering.
