A gear reducer is a mechanism to reduce speed by means of multi-stage gear transmission. The use of a small gear driving a large gear results in certain speed reduction. There are multiple pairs of gears which enable dramatically reduced speed.
The gear reducer, as a kind of gear parts, is generally applied to transmission with low rotating speed and high torque. It reduces the drive speed of the electric motor, internal-combustion engine or other high speed power unit through the engagement of a gear on the input shaft with a gearwheel on the output shaft.

The pivoting support is a large size bearing subjected to combined axial, radial loads and upsetting moment. It comes with mounting holes, internal/external gear, oil hole and seal, which enables compact structure, reliable performance and easy maintenance of the engine.
As a type of gear parts, the pivoting support is widely applied to large equipment such as hoisting machinery, mining machinery, construction equipment, harbor machinery, marine machinery, as well as high precision radar system and missile launcher, etc.
