Linear Joint – Paired Four-Point Contact Ball Bearing
Features: Designed for the front end of planetary roller screws, where installation space is limited; capable of handling large bidirectional axial loads while maintaining tight tolerances for axial displacement and angular misalignment. It employs a lightweight, slim‑profile paired four‑point contact bearing, which offers higher load capacity than deep‑groove ball bearings and significantly improved space efficiency compared to angular contact ball bearings. It is also suitable for applications such as security systems and automotive steering systems.
Linear joint—double-half inner ring four-point contact ball bearing
Features: Designed for the front end of planetary roller screws, where installation space is limited and the bearing must handle substantial bidirectional axial loads. Under certain high‑axial‑load conditions, four‑point contact ball bearings are prone to edge climbing; therefore, a double‑half inner ring configuration is employed to mitigate the risk of elliptical raceway truncation. This bearing can also be used in applications such as security systems and automotive steering systems.
Crossed roller bearing
Features: Crossed roller bearings, also known as cross‑roller bearings, typically feature cylindrical or tapered rollers arranged in a crossed configuration within the raceways. This arrangement enables a single bearing to simultaneously withstand axial loads, radial loads, and overturning moments, while maintaining a compact overall footprint. They are also suitable for applications such as security systems and machining centers.
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.
