Rack & pinion calculator
Module + teeth + torque (or force) → push force ↔ torque, linear speed, travel/rev.
How to use
- Enter the calculation conditions
Enter the dimensions, loads, speeds or operating conditions requested by the form.
- Run the calculation
The tool applies the formulas shown on this page to the entered values.
- Review the result
Review the resulting specification and checks, then verify them against the cited source, current standard and real operating conditions before use.
Core formula
d = m · z; F = 2,000 · T / d
Example using default values
d = 2 · 20 = 40 mm; π · d = 125.7 mm/rev
