Helical gears are used to achieve smooth and quiet operation.
The backlash is less than 3 arcmin and the positioning is accurate.
The use of integral ball bearings greatly improves the rigidity and torque.
It can be installed on any motor in the world.
The use of grease with high viscosity which is not easy to separate effectively prevents the grease leakage.
No need to replace the grease in the product life period, and the installation is more convenient.

A planetary gearbox is a gear system where the input shaft drives the central gear (sun gear), which then turns the surrounding gears (planet gears) inside an outer ring gear. This design offers high torque density, efficiency, and compactness.
The EVB series planetary gearboxes are ideal for high-precision operations such as servo motor applications, CNC machinery, robotics, automation systems, and printing equipment where precision and noise reduction are required.
Backlash refers to the play or clearance between the mating gear teeth. A backlash of less than 3 arcmin (arcminutes) ensures extremely high positioning accuracy, making the gearbox highly responsive with minimal lost motion.
Compared to spur gears, helical gears engage more gradually and smoothly. This leads to significantly quieter operation, lower vibration, and increased torque transmission capability, contributing to a longer service life.
No, the EVB series uses high-viscosity grease that resists separation and leakage. The gearbox is fully sealed, meaning it does not require grease replacement throughout its rated service life of 20,000 hours.
Yes. Because of its robust sealing design and construction, the EVB series planetary gearbox can be installed in any mounting position or direction without the risk of grease leakage.
