FRB Bearings produce thin wall bearing which can be divided into seven open series and five seal series.
The internal diameter ranges from 1 inch to 40 inches, and the cross-sectional dimensions range from 0.1875 x 0.1875 inches to 1.000 x 1.000 inches.
Open series have three types: radial contact (type C), angular contact (type A) and four-point contact (type X).
Sealed bearings have two types: radial contact (type C) and four-point contact (type X).
