QJ 1022 N2MA/C4 Bearing Product Overview & Core Advantages
The QJ 1022 N2MA/C4 is a high-precision Four Point Contact Ball Bearing engineered for exceptional performance in demanding applications. This single row bearing is designed to simultaneously accommodate significant combined radial and axial loads from both directions, making it an ideal solution for compact spaces requiring high rigidity and rotational accuracy. Manufactured to a P6 (ABEC-3) tolerance class, it ensures reliable operation and long service life in precision machinery.
QJ 1022 N2MA/C4 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| QJ 1022 | Standard designation for a four-point contact ball bearing with a 110mm bore and 170mm outside diameter. |
| N2 | Indicates the bearing has two machined grooves in the outer ring for retaining snap rings. |
| MA | Specifies a brass cage, which provides high strength and excellent performance at moderate speeds. |
| C4 | Denotes a radial internal clearance greater than normal (C4 group), suitable for applications with significant thermal expansion or interference fits. |
QJ 1022 N2MA/C4 Bearing Structural Features & Performance Benefits
The design of the QJ 1022 N2MA/C4 delivers distinct performance advantages:
- High Rigidity & Load Capacity: The four-point contact design and robust single row construction provide high rigidity, enabling the bearing to handle substantial combined loads (Radial Dynamic Load: 34,425 lbf, Static Load: 43,425 lbf) efficiently.
- Axial Load Management: Engineered specifically for applications requiring support for bidirectional axial loads in addition to radial loads, simplifying bearing arrangements.
- Precision & Speed: The P6 tolerance class and stable brass cage (MA) contribute to smooth operation and a high limiting speed of 6,300 rpm.
- Simplified Mounting: The N2 designation for snap ring grooves allows for easy axial location within a housing, reducing assembly complexity.
- Versatile Internal Clearance: The C4 clearance makes this bearing suitable for applications with expected thermal gradients or where tight fits are used.
QJ 1022 N2MA/C4 Bearing Typical Application Areas
This bearing is ideally suited for high-performance applications across various industries, including:
- Industrial Robots and Robotic Arms (for joint and rotary axis applications)
- Precision Machine Tool Components, such as rotary tables and indexing heads
- Wind Turbine Yaw and Pitch Systems
- Medical Imaging Equipment (e.g., CT scanners)
- Aerospace Actuation Systems
