  • Inch DUSTAC™ Shaft Seal
  • Suggested for pillow blocks used in extremely contaminated environments, such as taconite mines.
  • Provides protection against residual and airborne contaminants that exceeds the triple labyrinth shaft seal.
  • Contributes significantly to extending bearing life; reduces costs by helping prevent premature bearing damage.
  • Because of its unique design, no special finish is required on the shaft. DUSTAC is a patented device utilizing a V-shaped nitrile ring that rotates with the shaft and applies pressure to the cartridge face to exclude contaminates.
