BuraTAL <br/>HT 9650/HT For a larger view, please mouseover the image.
BuraTAL HT 9650/HT is based on braided end rings of expanded pure graphite with reinforced corners of carbon fiber yarn. In addition, the packing set consists of packing rings of expanded pure graphite, with very high density to maintain cross-sectional tightness under load. The adapter rings of very dense, expanded pure graphite are especially impregnated and have a friction reducing coating.
  • Extremely low leakage rate
  • Up to 80 % lower friction compared to standard sealing systems made of graphite
  • Very low decrease of radial sealing forces on spindle
  • Excellent resistance to gap extrusion
  • Minimized cold-flow and creep behavior
  • Very low spindle torques at high temperature and temperature cycling
  • Ideal for Standardisation
