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).

Note

Note: All units have a 1/8" pipe thread grease fitting

The Maximum Permissible Thrust Load applies to conditions of slip fit with set screw mounting or in applications where a large moment loading occurs. The values shown are valid only when two collars and set screws are used.

When heavy thrust forces are applied, the friction between the pillow block base may not be sufficient to prevent movement. Mechanical stops or shear bars with strength sufficient to support the load should be added. Never weld the pillow block or bearing to secure it to the shaft or base.
