QJ332-N2-MPA – Four-point bearing for precise axial guidance in both directions

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
The design utilizes Gothic Arch raceways, which form four contact points under axial load, ensuring axial force transmission. A split inner ring allows for a high ball count and simplifies assembly. The fit features a cylindrical bore. The open design is also included. Precisely machined raceways reduce friction and noise. A solid brass cage (MPA) further contributes to smooth operation. Manufacturing is performed to tolerance class P0. The design offers limited angular adjustability; therefore, precise alignment of the mating surfaces is essential.

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.
