QJ 1030 N2MA Bearing Product Overview & Core Advantages
The QJ 1030 N2MA is a metric single row four-point contact ball bearing engineered for high-performance applications requiring exceptional rigidity and precise operation. This precision bearing is distinguished by its ability to simultaneously support substantial combined loads—radial loads and axial loads in both directions—within a compact design. Manufactured to a P6 (ABEC-3) tolerance class, it ensures high running accuracy and reliability. The bearing comes pre-lubricated for immediate use and is designed for a wide operating temperature range, making it a robust and versatile solution for demanding industrial environments.
QJ 1030 N2MA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| QJ 1030 | Standard designation for a four-point contact ball bearing with a 150mm bore and 225mm outside diameter. |
| N2 | Indicates the bearing has two machined grooves in the outer ring for securing snap rings. |
| MA | Signifies that the bearing is filled with a specific, high-quality lubricant suitable for the designated operating conditions. |
QJ 1030 N2MA Bearing Structural Features & Performance Benefits
- Four-Point Contact & High Rigidity: The unique raceway design allows the bearing to handle combined radial and axial loads from both directions with a single bearing row, resulting in a very compact and highly rigid assembly.
- Superior Load Capacity: With a dynamic load rating of 54,450 lbf and a static load rating of 75,375 lbf, this bearing is built to withstand significant forces, ensuring long service life under demanding conditions.
- Precision & Speed Performance: The brass cage ensures stability and guides the balls effectively, contributing to smooth operation at the specified limiting speed of 4,500 rpm. The P6 tolerance class guarantees high precision for applications requiring minimal runout.
- Simplified Installation & Maintenance: The N2 snap ring grooves facilitate secure axial location within a housing, simplifying design and assembly. The pre-lubrication (MA) provides long-term, maintenance-free operation in many applications.
QJ 1030 N2MA Bearing Typical Application Areas
This bearing's combination of compactness, high load capacity, and precision makes it ideal for a range of demanding sectors, including:
- Industrial Robots (e.g., robotic arm joints and rotators)
- Precision Turntables and Indexing Tables
- Wind Turbine Yaw and Pitch Drives
- Medical Equipment (e.g., CT scanner gantries)
- Aerospace Actuation Systems
