IVANKO's Stainless Steel Needle
Bearing Olympic Bar.
When your goal is just to sell a product, your
Olympic bar design is finished when it's "good enough." When your goal is
perfection, you're never satisfied, never finished.
For example, a tensile strength of 150,000 PSI is
"strong enough" for most manufacturers. We heat treat our stainless steel bar to
218,000 PSI, because our tests tell us anything weaker will bend.
Most think bar stock is "straight enough" if it
meets the mil standard of 89/1000 inch over the 7ft length of the bar. We
further straighten our bar to a tolerance of 10/1000 inch, because anything less
straight will cause rotational torque during heavy lifting.
Most think there is a coating or plating that is
"durable enough." We chose stainless steel because it needs no coating, so
there's nothing to peel off, chip, or rust.
Most think a bar is "safe enough" just because
it's made of steel. We ultrasonic test and magnetic particle test every bar to
detect internal and external cracks and flaws because they can spread over time
and cause the bar to snap.
