Understand what backlash is and how gearbox type affects positioning accuracy, repeatability, and cost.
Section 1
What is Backlash?
Backlash is the small angular lost motion that occurs when a drive system reverses direction. It is caused by the mechanical clearance between mating transmission components, such as gears and gearboxes. During reversal, the input may begin moving before the output responds.

When rotation changes direction, a small clearance must be taken up before motion is transmitted to the output.

Economic Gearbox
Cost-effective solution for general industrial applications
Backlash: Higher
Positioning Accuracy: Standard
Repeatability: Moderate
Best For: General automation, conveyors, and cost-sensitive projects
Section 2 right
Precision Gearbox
Low-backlash solution for high-accuracy motion control
Backlash: Lower
Positioning Accuracy: High
Repeatability: Excellent
Best For: Robotics, indexing systems, CNC equipment, and precision automation
Bottom summary
Lower backlash improves positioning performance and repeatability. Choosing the right gearbox depends on your accuracy requirements, application demands, and budget.
