Latest Patents

Holtz's latest patents include a method of making a pin type bearing retainer. This innovative design involves stamping a pin type retainer for roller bearings in one piece from flat metal stock. The process begins with drawing the flat metal into a cup shape, featuring a broad flange around an open first end and a closed second end. The closed end provides solid support and alignment while stamping pins from the broad flange. The pins are then shaped by swaging or machining into various cross-sectional forms for diverse applications. The second end is subsequently opened to form a ring. This pin type retainer can be modified for use with a retaining ring or a seal against contaminants. Additionally, it can be formed from various materials, including steel, with an embodiment using plastic resin also disclosed.
