QJ330-N2-MPA-C3 – Four-point bearing for stable axial guidance in confined spaces

Quality that safeguards processes
The single-row four-point contact bearing accommodates axial loads in both directions, can withstand limited radial forces, and is suitable as a compact alternative to a bearing pair. The contact geometry ensures smooth running and defined axial guidance. This allows positioning tasks to remain reproducible even under varying operating conditions.

Design and manufacturing quality
Gothic Arch raceways create four contact points under axial load, reliably guiding axial force transmission. The split inner ring allows for a high number of balls, simplifying handling. The fit features a cylindrical bore and an open design. Finely machined raceways contribute to low friction and noise. A solid brass cage (MPA) further enhances smooth running. Manufacturing is performed to tolerance class P0. The design offers limited angular adjustability, requiring precise alignment of the mating surfaces.

Convincing in everyday life
In operation, the bearing impresses with reliable axial positioning on both sides, stable temperature and vibration values, and its small installation space requirement. For high pure radial loads, alternative bearing designs or a combined configuration are the better choice.

Summary
Compact, axially load-bearing on both sides and smooth running – for stable processes and reliable results in continuous operation.
