High-precision extra‑small, miniature, and thin‑walled deep groove ball bearings

Features: These ultra‑miniature bearings are designed for hollow‑cup motors, where precision and noise control are of paramount importance. In RV and planetary gear reducers, miniature and thin‑walled deep‑groove ball bearings are employed; they must meet extremely tight dimensional tolerances while delivering high precision and robust load‑carrying capacity. They are also suitable for applications in security systems, gear reducers, and other similar fields.

Product Description

Features: Special miniature bearings used in hollow‑cup motors place particular emphasis on precision and noise control. Meanwhile, miniature and thin‑walled deep‑groove ball bearings employed in RV and planetary gear reducers are subject to extremely tight dimensional constraints while also demanding high precision and robust load‑carrying capacity.

It can also be used in security applications, gear reducers, and other scenarios.

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.
