Ratings are based on strength calculation. Basic Static Strength Rating, or for h<strong>and</strong> operation of above gears is approximately 3 times the 100 RPM rating.<br />
NOTE: Ratings to right of heavy line are not recommended, as pitch line velocity exceeds 1000 feet per minute. Use for interpolation purposes only.<br />
