Planetary reducer is a kind of power transmission mechanism, which uses the gear speed converter to reduce the number of revolutions of the power source to the required number of revolutions and obtain a larger torque. The bearing of the planetary reducer plays the role of supporting the gear shaft or connecting rod in the rotating chamber.

The function of planetary reducer bearing:

1. Prevent the loss of gear lubricating oil in the bearing during use, and ensure that the bearing is in a lubricated state;

2. Prevent the dust or harmful gas outside the bearing from entering the bearing cavity and prevent the bearing from being damaged. 

So in daily work, what are the types of planetary reducer bearings? Reducer bearings are special equipment bearings used in all kinds of reducers, and some large reducers use self-aligning roller bearings.

What bearings does the planetary reducer have? Generally, it can be divided into 12 types, as follows:

1. Deep groove ball bearings and self-aligning ball bearings;

2. Angular contact ball bearings and cylindrical roller bearings;

3. Self aligning roller passes through bearing and tapered roller bearing;

4. Thrust ball bearing, thrust roller bearing, needle roller bearing;

5. Four row cylindrical roller bearings, double row tapered roller bearings;

6. Four row tapered roller bearings and two-way thrust ball bearings;

7. Thrust self-aligning roller through bearing, thrust calculation cylindrical roller fault bearing;

8. Thrust tapered roller bearings, thrust needle roller bearings, radial needle roller bearings and cage components, single row and double row needle roller bearings;

9. Single row needle roller bearing, no inner ring, needle roller bearing has a compressed outer ring;

10. Outer spherical ball bearing with tight set sleeve, four point contact ball bearing, self-aligning bearing with tight set sleeve, single row needle roller bearing;

11. Single and double row needle roller bearing without inner ring;

12. Spherical bearing with jackscrew and eccentric sleeve.

The above is an introduction to the types of planetary reducer bearings. If you need planetary reducer, please consult the manufacturer of Newgear.
