  • 1 C90 is the Dynamic Load Rating based on a rated Life of 90 million revolutions (3000 hrs at 500 RPM).
  • 2 Fa-max is based on the limits of the holding force of two properly tightened collars and set screws. Fifty percent of the values should be used when a single collar is installed.
  • 3 If the application loads approach or exceed Fr-max, the shaft fit should be adjusted to a line-to-line (g6 or h6) or light press fit (m6).
