T Symbol denotes Basic Dynamic Load Rating to be used in load-life
calculations taking into consideration the application guidelines and limitations given
in this catalog. Applications involving loads approaching this rating or the tabulated
working load, whichever is the smaller, should be referred to the Torrington
Engineering Sales Office before a final selection is made.

Check for availability.
Inch-metric conversions given are
for the convenience of the user. The
controlling dimensions are in inches
for nominal inch bearings and in
millimeters for nominal metric
bearings.
Load ratings are based on a minimum raceway hardness of 58 HRC or equivalent.
Load ratings are given in pounds-force: 1 lbf = 0.454kgf = 4.448N
Required Basic Dynamic Load Rating (Cr) = Applied Load • SF • LF • HF (see page E75).
