QJ 310 PHAS Bearing Product Overview & Core Advantages
The QJ 310 PHAS is a metric four-point contact ball bearing engineered for high-performance applications requiring exceptional precision and load handling. This single-row bearing is distinguished by its ability to simultaneously support substantial radial loads and axial loads in both directions with a compact cross-section. Manufactured to P6 (ABEC-3) tolerance class, it delivers high running accuracy and reliability. The optimized design, featuring a Peek cage and pre-lubrication, ensures smooth operation at high speeds, making it an ideal solution for demanding rotational systems.
QJ 310 PHAS Bearing Model Code Explained, Specifications & Naming Convention
The model designation QJ 310 PHAS provides specific technical information:
- QJ: Denotes the four-point contact ball bearing series.
- 310: Specifies the standard bore diameter (50 mm) and dimensional series.
- PHAS: Indicates the bearing is supplied with a special high-performance grease suitable for the specified operating temperature range.
QJ 310 PHAS Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The four-point contact raceway design enables the bearing to handle significant combined radial and axial loads from both directions efficiently, providing a rigid and stable support structure.
- Precision & High-Speed Performance: Built to a P6 tolerance class, it guarantees precise shaft guidance and low vibration. The lightweight and robust Peek cage contributes to a high limiting speed of 11,000 rpm, ensuring stable operation in high-velocity applications.
- Optimized Material & Lubrication: Components made from chrome steel offer high durability and fatigue resistance. The bearing is pre-lubricated with a special grease (PHAS), providing long-term performance within a temperature range of -30°C to 110°C.
- Compact & Lightweight Design: With a bore diameter of 50 mm and a width of only 27 mm, this bearing offers a high load capacity in a minimal space, contributing to overall system weight reduction.
QJ 310 PHAS Bearing Typical Application Areas
The QJ 310 PHAS is ideally suited for high-precision and high-speed machinery, including:
- Industrial Robotic Arms and Gearing Systems
- High-Speed Machine Tool Spindles and Rotary Tables
- Precision Gearboxes and Drive Systems
- Aerospace Actuators and Control Mechanisms
