Magneto Magnetic Bearing EN13 E series Angular contact ball bearing E13 13x30x7mm
The internal design of magnetic bearings is ideal for applications involving low loads and high speeds and is essentially similar to a single row deep groove ball bearing. However, the outer ring is a counter cavity with a grooved track that merges into the cylindrical track, making it easy to separate the two components.
If you want to know more details, please feel free to contact us.
The inner groove of the magnetic bearing is slightly shallower than the deep groove. Since the outer ring has shoulders on only one side, the outer ring can be removed. This is usually useful for installation.
This means that the outer ring of the magnetic bearing can be mounted separately from the inner ring and cage. Therefore, magnetic bearings are easier to install, install and remove than standard deep groove ball bearings.
The most common application uses two of the bearings in a double pair. These bearings are placed opposite each other, leaving a small amount of final play. Magnetic bearings are usually small, with bores between 4mm and 30mm. They exist in a range of applications, including gyroscopes and small magnets. They can also be used as support bearings for the ends of ball screws on small milling machine tables and as support bearings in generators and starter motors.
To choose the best results for a particular job, many factors must be considered. These include payload capacity, allowable load space and allowable speed. Bearing types may also depend on the specific bearing arrangement chosen for the project.

Magnetic bearing magneto bearing
1.The inner ring groove is slightly lighter than the deep groove ball bearings, the inner diameter of the outer ring without ribs from the side of the circular cylindrical outer ditch
2. The outer ring can be separated for easy mounting bearings.
3. Normally, the two opposing bearing use. This bearing is an inner diameter of 4-20mm small bearings.
4. Mainly used for small generators, gyroscope, measurement instruments.
5. Usually made of copper alloy stamping cage.
