QJ 1032 N2MA Bearing Product Overview & Core Advantages
The QJ 1032 N2MA is a Four Point Contact Ball Bearing designed for exceptional performance in demanding applications. This metric single row bearing is engineered to simultaneously withstand combined loads, including radial loads and axial loads in both directions, within a compact design. Its P6 (ABEC-3) tolerance class ensures high running accuracy, making it ideal for high-precision and high-reliability machinery. The bearing comes pre-lubricated for immediate use and offers a wide operating temperature range.
QJ 1032 N2MA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| QJ 1032 | Standard designation for a four-point contact ball bearing with a 160mm bore. |
| N2 | Indicates two machined circumferential grooves in the outer ring for lubrication. |
| MA | Specifies the bearing is filled with a specific high-temperature, high-speed grease. |
QJ 1032 N2MA Bearing Structural Features & Performance Benefits
- Four-Point Contact Design: The optimized raceway geometry allows the bearing to handle combined radial and axial loads from both directions with a single bearing row, saving space and weight.
- High Load Capacity: With a dynamic load rating of 60,750 lbf and a static load rating of 85,500 lbf, it offers robust performance under significant stress.
- Precision & Rigidity: Manufactured to P6 tolerance and featuring a brass cage, the bearing ensures smooth operation, high rigidity, and stable running at the limiting speed of 4,300 rpm.
- Optimized Lubrication: The N2 grooves facilitate efficient grease distribution, while the pre-applied MA grease ensures reliable operation across the specified temperature range (-30° to 110 °C).
