Olympic Workout Bar Terminology

  • Tensile Strength: The force to pull apart material (breaking)
  • Yield Strength: The force to create a permanent bend
  • PSI: Pounds Per Square Inch
  • 190K PSI Tensile: 190,000 lbs per square inch of force required to break or tear apart.
  • Corrosion Resistance: The ability to combat the elements such as salt, air, sweat, etc.
  • Raw Steel: No finish to protect. Very easy to rust.
  • Zinc Plating: Either Black, Silver or Gold color. A very superficial finish providing moderate corrosion resistance. Inexpensive.
  • Black Oxide: Black coating that has minimal corrosion resistance. Inexpensive.
  • Chrome: Used for cosmetic purposes like car parts, faucets, etc. Very good corrosion resistance but very dangerous for Olympic Bars. Chrome can flake and peel causing severe lacerations to the user. Moderately expensive.
  • Hard Chrome: Moderate corrosion resistance. Very hard finish, cosmetically appealing and will not peel or cut. Used predominantly in the aircraft industry. Expensive.
  • Stainless Steel: Very good corrosion resistance. It can always be cleaned or repaired with no damage to the finish. Very expensive for material and machining costs.
  • Cerakote Finish: Excellent corrosion resistance when properly cared for. Expensive.
  • Needle Bearings: A bearing with hardened needle shaped pieces in a cage that rotate around the workout bar.
  • Bushings: Either Bronze or a type of Nylon. Used inside workout bar sleeves for smooth rotation.
  • IPF: International Power Lifting Federation.
  • IWF: International Weightlifting Federation.
  • Shaft: The long section in the middle of the workout bar where the user grips.
  • Sleeves: The rotating ends on the workout bar where you load the plates.
  • 28MM, 28.5MM, 29MM, etc.: Refers to the diameter of the workout bar shaft.
  • IWF OR IPF Spec.: Precise specifications of the workout bar dictating hand grip locate points, workout bar diameter, knurl lengths, sleeve diameters, etc. An IWF workout bar has wider locating marks for hand gripping and usually a smaller diameter than an IPF workout bar.
