PG28A-PM-HT 28mm diameter Powder metallurgy Helix Teeth Planetary gearbox

1. Give full play to the advantages of stability, security and reliability

The star reducer can give full play to the advantages of stability, safety and reliability, especially to meet the requirements of various complex working environments, and can also reduce the speed, increase the torque and reduce the load. Furthermore, there are no special maintenance requirements to ensure an automated operating process.

2. Strong anti-seismic effect

The planetary reducer has a precise transmission function during work, especially has a strong anti-seismic function, and has an extremely long service life during work. Because we don't need special maintenance, we can reduce the cost of use and avoid unexpected failures during work.

In short, the planetary reducer can play the performance of these important advantages in operation and meet the requirements of various working environments.
