Calculation method
Calculation method
Rotor diameter increase (mm)
Candidate diameter−original diameter.
Required nominal radial movement (mm)
Diameter difference/2.
Candidate nominal radial offset (mm)
Existing nominal offset+required radial movement.
Exact matches in supplied offset list (mm)
Find supplied nominal offsets equal within scale-relative numerical roundoff.
Symbols and units
- a
- Original nominal rotor diameter (mm)
- b
- Candidate nominal rotor diameter (mm)
- c
- Existing nominal adapter radial offset (mm)
- d
- Explicitly available nominal radial offsets (mm)
Use the units shown. A list keeps the order in which you enter its values. The symbol ^ means “raised to the power of”.
Assumptions & limits
Assumptions & limits
- Nominal radius arithmetic only. Matching a number does not establish mounting-standard, bolt, rotor, fork or brake compatibility; no physical adapter is selected.
