C₉₀ Dynamic Load Rating¹	N/A 3810 lbf
C₀ Static Load Rating	N/A 15760 lbf
F_a-max Maximum Permissible Thrust Load²	N/A 2000 lbf
F_r-max Maximum Allowable Slip Fit Radial Load³	N/A 3100 lbf
Max. Speed⁴	N/A 4490 rpm

¹ C₉₀ is the Dynamic Load Rating based on a rated Life of 90 million revolutions (3000 hrs at 500 RPM).
² F_a-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 F_r-max, the shaft fit should be adjusted to a line-to-line (g6 or h6) or light press fit (m6).
