These are great motors and they are very strong. They are operating quietly, and also need them to release their hold every time a move is complete.

Please develop more low noise gearbox and with better prices, so we can sell your products to more clients and gain larger markets. Thank you.

I purchased the 3-pack of the smaller steppers for my current ender 3 pro project. For my applications, they work perfectly. It's a great deal for quality motors, and I'm going to purchase another 10 packs.

Product Description

Precision gearbox High Reduction Ratio Gearbox 60mm 90mm 104mm 115mm

Advantages of planetary gearbox:

1. Large transmission speed ratio. The gear meshing transmission of the planetary reducer has multiple sets, the number of gear sets is large, and the transmission speed ratio increases accordingly.

2. High carrying capacity. This is because the reducer has many teeth meshing with the gear transmission at the same time, and the material used for the rack is very strong. After precision machining, the overall carrying capacity of the planetary reducer is effectively improved.

3. High transmission precision. The meshing precision between the gears is high, which can be less than 1 arc minute. Compared with other types of reducers, it is a high-precision reducer.

4. High efficiency and stable movement.
