QJ 1076 N2MA Bearing Product Overview & Core Advantages
The QJ 1076 N2MA is a four-point contact ball bearing designed for exceptional performance in demanding applications. This precision bearing is engineered to simultaneously handle combined loads, including radial loads and axial loads in both directions, making it an ideal solution for compact, high-rigidity designs. Manufactured to a P6 (ABEC-3) tolerance class, it ensures high running accuracy and reliability. Its open design and high-quality materials contribute to its robust load capacity and stable operation within a wide temperature range.
QJ 1076 N2MA Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| N2 | Indicates the bearing has two machined grooves in the outer ring for lubrication. |
| MA | Signifies that the bearing is supplied with a specific, high-performance lubricant from the manufacturer. |
QJ 1076 N2MA Bearing Structural Features & Performance Benefits
- Four-Point Contact Design: The unique raceway geometry allows the bearing to accommodate significant axial loads from both directions, as well as radial loads, all within a single-row, space-saving construction. This results in a highly compact bearing with a large bore diameter.
- High Load Capacity: With a dynamic load rating of 198,900 lbf and a static load rating of 459,000 lbf, this bearing is built to withstand heavy combined loads in challenging environments.
- Precision & Rigidity: The P6 tolerance class ensures precise dimensions and smooth operation, while the robust construction with a brass cage provides high rigidity and stable rotational characteristics.
- Optimized Lubrication: The N2 grooves facilitate effective re-lubrication, extending service life. The pre-applied lubricant (MA) is suitable for a temperature range of -30°C to 110°C.
