Myers Disperser Blade Bore

Myers Engineering makes use of a very common design in driving their disperser blades. CENTER BORE and PIN HOLES: A center hole is drilled in the blade. Two (2) or four (4) pin holes are drilled around the center hole. Drive pins extend from a hub through the blade and typically extend into a lower plate or washer. Torque is transfered from these pins to the pin holes in the dispersing blade. This design is used throughout the horsepower range and blade size range. As blade diameter increases, the distance between pinholes and/or the number of pinholes is increased.

Some of the more common Myers blade arrangements include:

  • 5/8" center Hole and two (2) 7/16" pinholes on a 2-3/4" bolt circle
  • 3-1/4" center Hole and teo (2) pinholes on a bolt circle
  • 5" center Hole and four (4) pinholes on a bolt circle
