In small devices like home appliances or smart equipment, sticky or resistant gear movement is quite common.

This issue can affect both performance and user experience.

Typical reasons include:

• Grease viscosity too high or too low
• Poor compatibility with plastic materials
• Uneven grease distribution

We’ve seen many cases where the issue was resolved simply by adjusting the lubrication.

For plastic gears, it’s important to use grease designed for low friction and material safety.

If the problem already exists, lubrication is usually the first thing to check.
