QJ 316 N2PHAS Bearing Product Overview & Core Advantages
The QJ 316 N2PHAS is a Four Point Contact Ball Bearing designed for applications requiring exceptional precision and load-handling capabilities. This single row bearing is engineered to simultaneously support combined loads, including significant radial loads and axial loads in both directions, making it an ideal solution for compact, high-rigidity arrangements. Manufactured to P6 (ABEC-3) tolerance class and featuring a Peek cage, it delivers reliable performance in demanding operational environments.
QJ 316 N2PHAS Bearing Model Code Explained, Specifications & Naming Convention
The QJ 316 N2PHAS model designation provides specific technical information:
- QJ 316: Denotes the bearing series and basic dimensions (80mm bore, 170mm OD, 39mm width).
- N2: Indicates the bearing has two integral guide ribs (or lands) on the outer ring for precise axial location.
- P: Signifies a glass-fiber reinforced PEEK cage, offering high strength, low friction, and excellent performance at high speeds and temperatures.
- H: Represents a hardened bearing, providing increased durability and load capacity.
- A: Specifies a 30° contact angle, optimized for handling high axial loads.
- S: Indicates the bearing rings are dimensionally stabilized (stabilized heat treatment) for consistent performance.
QJ 316 N2PHAS Bearing Structural Features & Performance Benefits
- Four Point Contact Design: The unique raceway geometry allows the bearing to accommodate combined radial and axial loads from any direction with a single bearing, simplifying design and saving space.
- High Rigidity & Precision: Built to P6 tolerance class with a hardened structure, this bearing ensures minimal deflection and high running accuracy, which is critical for precision machinery.
- High-Speed Capability: The lightweight and robust PEEK cage minimizes centrifugal forces, reduces friction, and enables a high limiting speed of 7,000 rpm.
- Superior Load Capacity: With a dynamic load rating of 52,200 lbf and a static load rating of 51,300 lbf, it is built to withstand heavy-duty operational demands.
- Optimized for Lubrication: The open design allows for versatile lubrication schemes, ensuring effective lubrication film formation and long service life within a temperature range of -30°C to 110°C.
QJ 316 N2PHAS Bearing Typical Application Areas
This bearing is ideally suited for applications requiring high precision and the ability to handle complex load scenarios, including:
- Machine Tool Spindles
- Industrial Robots and Rotary Joints
- Precision Gearboxes
- Turntables and Indexing Tables
- Aerospace Actuation Systems
