New Energy Electric Drive – Ceramic Ball Bearings

Features: Insulating, ultra‑high speed, high precision, long service life, suitable for high‑temperature, low‑temperature, and corrosive environments. Advantages: Ceramic ball bearings are the best insulating bearings; at the same rotational speed, they exhibit a lower temperature rise compared to steel ball bearings, enabling higher maximum speeds. When paired with appropriate cage materials and lubricants, they can operate in high‑temperature, cryogenic, and corrosive environments. They are also applicable to high‑speed permanent‑magnet water pumps, high‑speed permanent‑magnet motors, and high‑power permanent‑magnet motors, among others.

Product Description

Features: Insulating, ultra‑high speed, high precision, long service life, suitable for high and low temperatures, and corrosion‑resistant.

Advantages: Ceramic ball bearings are the best insulating bearings; at the same rotational speed, they exhibit a lower temperature rise compared to steel ball bearings, thereby achieving a higher maximum speed. When paired with appropriate cage materials and lubricants, they can be used in high‑temperature, cryogenic, and corrosive environments.
It can also be applied to high-speed permanent-magnet water pumps, high-speed permanent-magnet motors, or high-power permanent-magnet motors, among others.

Single-row deep groove ball bearing

It is the most typical structural form among rolling bearings and finds wide application. In addition to supporting radial loads, it can also accommodate axial loads in both directions. With a low friction torque, it is ideally suited for applications requiring high-speed rotation, low noise, and minimal vibration.

Angular contact ball bearing

They are primarily used in high-speed rotating applications with relatively light loads and can withstand combined radial and axial loads. When installed in pairs, angular contact ball bearings can handle combined radial and axial loads, with the radial component being dominant, and they can also accommodate purely radial loads. In a tandem arrangement, they can only support axial loads in one direction, whereas the other two arrangements can accommodate axial loads in either direction.

Cylindrical roller bearing

Cylindrical roller bearings are line-contact bearings. They offer high load-carrying capacity and primarily support radial loads. The rolling elements experience low friction against the raceway shoulders, making them well suited for high-speed operation. Depending on whether the rings are equipped with shoulders, they can be classified into single-row cylindrical roller bearings—such as NU, NJ, NUP, N, and NF—and double-row cylindrical roller bearings—such as NNU and NN.
