Backlash Explained: Economic vs. Precision Gearboxe

Backlash Explained: Economic vs. Precision Gearboxe

Subtitle

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.

Section 2 left

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.
