Rack and pinion drives provide the mechanism to turn rotary motion into linear motion. To provide the correct product for your application we require certain details as a minimum:
- Torque on pinion
- RPM of gear
- Linear speed of rack
- Linear force,
- Dimension restraints
- Duty cycle
Depending on your application requirement the rack drive may need to be hardened and ground to achieve greater accuracies and higher duty cycles. Environment issues of humidity, dust, salinity, acidity or other factors that might have an impact of the functioning and life of the rack and gear drive need to be considered in the design and selection process.
