42BYGHM CE ROHS ISO gear stepper motor dc with 36mm or 42mm planetary gearbox
The NEMA 17 stepper motor can choose from 36mm or 42mm gearbox. The 36 mm gearbox has 2 housing material-- powder metallurgy and zinc alloy. The rated tolerance torque of 42mm gearbox is 10Nm and max momentary tolerance torque is 30Nm.
The 36mm Zinc alloy gearbox is more cost-effective. This gearbox reduction ratio is 1/12, rated tolerance torque is 0.3Nm, and max momentary tolerance torque is 1 Nm.

Planetary gears are slightly expensive compared to traditional gears. However, they guarantee a high ROI.
Design is quite complex thou they are efficient and still easy to maintain.
From this, you can see that the planetary gearbox has many advantages.
1.Increased repeatability: Its greater speed radial and axial load offer reliability and robustness, minimizing the misalignment of the gear.
2.Perfect precision: Most rotating angular stability improves the accuracy and reliability of the movement.
3.Lower noise level because there is more surface contact. Rolling is much softer and jumps are virtually nonexistent.
4.Greater durability: Due to its torsional rigidity and better rolling. Thus, greater efficiency of the gear and a much smoother operation is achieved.
5.Very good levels of efficiency: Planetary reducers offer greater efficiency
6.Increased torque transmission: With more teeth in contact, the mechanism is able to transmit and withstand more torque. In addition, it does it in a more uniform manner.
7.Maximum versatility: Its mechanism is contained in a cylindrical gearbox, which can be installed in almost any space.
