QJ 212 N2PHAS Bearing Product Overview & Core Advantages
The QJ 212 N2PHAS is a metric single row four-point contact ball bearing engineered for applications requiring exceptional precision and load handling capabilities. This precision bearing is distinguished by its ability to simultaneously support 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 and pre-lubricated, it delivers reliable performance in demanding operational environments.
QJ 212 N2PHAS Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| N2 | Indicates snap ring grooves on the outer ring, facilitating secure axial location and simplified mounting. |
| P | Specifies the Peek (Polyetheretherketone) cage material, offering high strength, low friction, and excellent performance at elevated temperatures. |
| H | Denotes a hardened bearing, providing increased durability and resistance to wear. |
| A | Signifies an optimized internal design for enhanced performance under combined loads. |
| S | Indicates the bearing is supplied with a lubricant suitable for the specified temperature range. |
QJ 212 N2PHAS Bearing Structural Features & Performance Benefits
- Four-Point Contact Design: The unique raceway geometry allows the bearing to handle significant combined radial and axial loads from any direction with a single bearing row, resulting in a compact and space-saving solution.
- High Rigidity & Precision: Manufactured from chrome steel with a P6 tolerance class, this bearing ensures minimal runout and high rotational accuracy, which is critical for precision applications.
- Optimized for High Speeds: The lightweight and robust Peek cage minimizes centrifugal forces, contributing to a high limiting speed of 10,000 rpm.
- Simplified Mounting & Axial Security: The outer ring snap ring grooves (N2) allow for easy axial location within a housing, reducing assembly complexity and parts count.
- Robust Load Capacity: With a dynamic load rating of 21,712 lbf and a static load rating of 20,925 lbf, it is built for long service life under demanding conditions.
QJ 212 N2PHAS Bearing Typical Application Areas
The QJ 212 N2PHAS is ideally suited for high-performance applications across various industries, including:
- Robotics and Automation: Used in robot arm joints and rotary actuators where compactness, precision, and multi-directional load capacity are paramount.
- Machine Tool Components: Ideal for rotary tables, indexing heads, and other precision positioning systems.
- Aerospace & Defense: Employed in radar systems, gyroscopes, and other instrumentation requiring high reliability and accuracy.
