QJ 314 N2PHAS Bearing Product Overview & Core Advantages
The QJ 314 N2PHAS is a Four Point Contact Ball Bearing designed for exceptional performance in demanding applications. As a single row bearing with a unique raceway geometry, it can simultaneously support combined loads, including high radial loads and axial loads in both directions. Its compact design and high rigidity make it an ideal choice for applications requiring precise positioning and high operational reliability. Manufactured to a P6 (ABEC-3) tolerance class, it ensures consistent, high-precision performance.
QJ 314 N2PHAS Bearing Model Code Explained, Specifications & Naming Convention
- QJ 314: Standard designation for a Four Point Contact Ball Bearing with a 70mm bore and 150mm outside diameter.
- N2: Indicates snap ring grooves on the outer ring, facilitating secure axial location and simplified housing design.
- P: Signifies a glass fiber reinforced PEEK (Polyetheretherketone) cage. This material offers high strength, low weight, and excellent performance at high speeds and temperatures.
- H: Denotes a hardened bearing, contributing to increased load capacity and extended service life.
- A: Specifies a 30° contact angle, optimized for supporting significant axial loads.
- S: Indicates the bearing is supplied lubricated from the factory for immediate use.
QJ 314 N2PHAS Bearing Structural Features & Performance Benefits
Four Point Contact Design: The unique raceway geometry allows a single bearing to handle combined radial and bidirectional axial loads efficiently, simplifying assembly and saving space compared to traditional bearing arrangements.
High Load Capacity: With a dynamic load rating of 45000 lbf and a static load rating of 40500 lbf, this bearing is engineered for robust performance under heavy loads.
High-Speed Capability: The lightweight and durable PEEK cage ensures stable operation and low friction, contributing to a high limiting speed of 8000 rpm.
Precision & Rigidity: The P6 tolerance class and hardened construction provide high running accuracy and high rigidity, which is critical for applications with minimal deflection requirements.
Convenient Mounting: The snap ring grooves (N2) allow for easy axial fixation, reducing the complexity and cost of the surrounding housing structure.
QJ 314 N2PHAS Bearing Typical Application Areas
The QJ 314 N2PHAS is ideally suited for a wide range of industrial machinery where compactness, high load capacity, and precision are paramount. Key applications include:
- Robotics (e.g., joint and arm rotation)
- Machine Tool Components (e.g., rotary tables, indexing heads)
- Material Handling Equipment (e.g., turntables, slewing rings)
- Aerospace Actuation Systems
- Medical and Precision Equipment
