Planetary Gearbox

Planetary Gearbox

The structural characteristic of a planetary gearbox is that multiple planetary gears rotate around a sun gear. This configuration enables the planetary gearbox to proportionally increase the motor torque while reducing the transmission speed ratio. With its compact size and efficient structure, the planetary gearbox can deliver greater transmission capacity within limited space.

The bearings in a planetary gearbox operate directly within the bores of the planetary gears, which are designed by gearbox manufacturers to serve as bearing raceways. Extremely high transmission ratios can be achieved within the smallest radial design envelope, while eliminating the risk of outer ring damage caused by co-rotation or fretting corrosion.

IDC delivers robust bearing solutions tailored for planetary gearboxes:

Ball Bearings

Ball Bearings

IDC's ball bearings include radial and thrust types. Radial ball bearings mainly comprise deep groove and angular contact variants. Thanks to point contact between rolling elements and raceways, these bearings deliver high precision, low friction, quiet operation, and are well-suited for high-speed applications.

Cylindrical Roller Bearings

Cylindrical Roller Bearings

IDC cylindrical roller bearings are available in a wide range of designs and sizes. Key variations include the number of roller rows, inner and outer ring flange configurations, and cage designs and materials. These bearings are ideal for applications involving heavy radial loads and high speeds. They also accommodate axial displacement — particularly in designs with flanges on both rings, which allow limited axial movement. Additional advantages include high rigidity, low friction, and extended service life.

Track Roller Bearings

Track Roller Bearings

IDC track roller bearings are a special type of bearing that utilize rollers as rolling elements and combine the structure of rolling bearings with that of rollers. They are primarily designed to bear radial loads while also accommodating a certain degree of axial displacement or angular misalignment. The outer ring features a thick-walled structure. These bearings are widely used in mechanical devices that require rolling support, guidance, or motion transmission.
