QJ 232 N2MA Bearing Product Overview & Core Advantages
The QJ 232 N2MA is a four-point contact ball bearing designed for applications requiring exceptional load capacity and precision. This single-row bearing excels at simultaneously handling combined loads, including radial loads and axial loads from both directions, making it an ideal solution for compact, high-rigidity designs. Manufactured to P6 (ABEC-3) tolerance class, it delivers the high running accuracy essential for demanding industrial equipment. Its open design and pre-lubrication facilitate optimal performance within a broad operating temperature range.

QJ 232 N2MA Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The four-point contact design and robust brass cage enable the bearing to support significant combined radial and axial loads from any direction, providing a highly rigid and stable rotational element.
- Precision Performance: Manufactured to a P6 tolerance class, this bearing ensures minimal runout and high positional accuracy, which is critical for precision machinery.
- Optimized for High-Speed Operation: The combination of the brass cage and specialized lubrication (MA) allows for a high limiting speed of 3,800 rpm, making it suitable for demanding rotational applications.
- Simplified Mounting: The snap ring grooves (N2) on the outer ring facilitate secure axial location within the housing, simplifying assembly and maintenance.
- Durable Construction: Components made from chrome steel for both rings and balls ensure high durability, long service life, and reliable operation under heavy loads.
