Bearing with 1 Inch Inner Diameter and Race with 1.966 Inch Diameter

Expert Reply:

If you are talking about the inner diameter then the only bearing we have with a 1 inch inner diameter is # L44643. The matching race is # L44610 and it has an outer diameter of 1.980 inches. For a 1 inch spindle nut we have # 165686.

The best way to determine the correct replacement bearings is to go by the inner and outer bearings numbers that are stamped into the metal on the sides of the bearings. Otherwise you would need to measure the spindle using dial or digital calipers for the most accurate measurements you can get. I have included a picture that shows the measurements needed and how the correspond to the bearings and races.
