QJ334-N2-MPA-C3 – Four-point bearing for axial double guidance in a compact design

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, ensuring reliable axial force transmission. The split inner ring increases the number of balls and simplifies assembly. The fit features a cylindrical bore and an open design. Carefully ground raceways reduce friction and noise. A solid brass cage (MPA) further enhances smooth operation. Manufacturing is performed to P0 tolerance. The design offers limited angular adjustability, requiring precise alignment of the mating surfaces.

Convincing in everyday life
In practice, the design ensures secure axial positioning in both directions, constant temperature and vibration levels, and space-saving integration. For predominantly high pure radial loads, other bearing designs or a combined concept are recommended.

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