To obtain load ratings at other RPM or hours of life, multiply the basic load rating
above by the appropriate life and speed factors from the chart below. These values
are recommended only, since operating conditions can vary considerably from our
laboratory tests.

 


A Series Load Ratings

The following load ratings, in pounds, are the result
of extending the data developed in many individual
tests at various RPM’s and applied loads:

H Series Load Ratings

The following load ratings, in pounds, are based on standard AFBMA
computations for these bearings at 2500 hours average life or 500 hours
minimum life.  Outer race rotation.
