Wheel Adapter Parts.
Flanges.


Performance always matters, even for as basic an item as a flange; and performance begins with design. At Sopko we make flanges with customer safety in mind. Check these design features and you’ll know what we’ve known for a long time, SAFETY FIRST!

  • BEARING SURFACES GROUND FLAT AND PARALLEL to assure maximum uniform wheel contact.

  • PRECISION GROUND OD AND ID for optimum CONCENTRICITY AND BALANCE.
  • SPECIALLY SELECTED ALLOY STEEL HEAT TREATED FOR MAXIMUM STRENGTH AND TOUGHNESS.
  • FLANGES ARE RECESSED to produce equal and opposite bearing surfaces, keeping stress away from the wheel bore
