NOTE: FMS = From Mounting Surface
Resistance Tolerance: K =
Resistance Code: Expressed in ohms. A three digit code where the first
two digits are significant figures, and the third digit indicates the number
of zeros that follow these figures. R indicates decimal point for resistance
less than 10Ω (i.e., 5R0 = 5Ω; 100 = 10Ω; 101 = 100Ω; 102 = 1,000Ω;
103 = 10,000Ω ). See table for standard resistance values.

Specify taper and resistance code as shown.
Specify a taper code and resistance code for each unit starting with
the front unit followed by the rear unit. If both units have the same taper
and resistance codes, add “X2” suffix per example below.
Examples: B103A503 or if both units are the same: B103X2
Specify the shaft length (FMS) and shaft end style as shown.
Specify the shaft length (FMS) and shaft end style for the inner shaft
followed by the shaft length (FMS) and shaft end style for the outer
shaft. Use a dash (-) to separate the code groups for the inner and
outer shaft specifications. Example: 30R-20R
