71815 ACDGA/P4 Bearing Product Overview & Core Advantages
The 71815 ACDGA/P4 is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Engineered to accommodate combined loads, it efficiently handles both radial loads and substantial axial loads in one direction. Its compact design with a 10 mm width makes it ideal for space-constrained, high-performance assemblies. Manufactured to a P4 tolerance class, this bearing guarantees superior running accuracy and rotational precision, making it a cornerstone component for advanced machinery.
71815 ACDGA/P4 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle. |
| D | Optimized internal geometry for high-performance applications. |
| GA | Indicates a specific internal clearance and preload group for Universal Matchable (SU) mounting. |
| /P4 | Denotes a high-precision tolerance class for superior running accuracy. |
71815 ACDGA/P4 Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The angular contact design and 25° contact angle provide excellent rigidity, enabling the bearing to support significant combined radial and axial loads.
- Precision Performance: Manufactured to P4 tolerance standards with tight dimensional controls on the 75 mm bore and 95 mm outside diameter, ensuring minimal runout and vibration for smooth operation.
- High-Speed Capability: The lightweight phenolic cage and optimized internal design contribute to a high limiting speed of 28,000 rpm, reducing centrifugal forces and operational temperatures.
- Universal Matching: Designed as a Universal Matchable (SU) bearing, it can be mounted in sets (up to 4 bearings) to achieve preloaded configurations for maximum system stiffness and accuracy.
- Durable Construction: Components made from chrome steel offer high fatigue resistance and longevity, suitable for a wide temperature range of -30°C to 110°C.
