In 1935, the Sealmaster® ball bearing was born. By 1946, the business had grown to a point where they built a new facility devoted to the exclusive manufacturing of ball bearings. Today, although they have expanded their product offering, they continue their focus on performance products.

They are positioned to grow their numerous specialty products, while maintaining their commitment to developing more problem solvers like the corrosion-resistant beverage bearing.

Contributing to the growth of the specially-designed Sealmaster bearing were these important features:
  • A locking pin and dimple system that prevents outer race rotation and ensures positive lubrication
  • A land riding brass retainer which minimizes ball wear
  • The felt-lined flinger seal for effective sealing against dirt
  • The inner race ball-path is zone hardened, so that the extended section could be left in its original soft state. Thus, the set- screw holes locking the unit to the shaft could be drilled and tapped
