S71913 ACDGC/P4A Bearing Product Overview & Core Advantages
The S71913 ACDGC/P4A is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. This sealed bearing features a phenolic cage and is preloaded to Moderate / Class C, making it ideal for handling combined loads (radial and axial) simultaneously. Its compact design, with a 65 mm bore and 13 mm width, offers a high load capacity in a minimal space. Manufactured to the stringent P4A tolerance class, it ensures superior running accuracy and is universally matchable, allowing for precise preload control when used in sets.
S71913 ACDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | Angular Contact Design with a 25° contact angle, optimized for high axial load capacity. |
| GC | Indicates a specific internal clearance and preload group (Moderate / Class C). |
| P4A | Denotes a high-precision tolerance class with enhanced dimensional and running accuracy. |
S71913 ACDGC/P4A Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 25° contact angle and robust construction enable the bearing to support significant combined radial and axial loads, providing stable and rigid support for shafts.
- High-Speed Performance: The lightweight phenolic cage minimizes centrifugal forces, contributing to a high limiting speed of 31,000 rpm, making it suitable for high-speed applications.
- Precision and Longevity: Manufactured to P4A tolerances from chrome steel, this bearing ensures minimal vibration and extended service life under demanding conditions.
- Maintenance-Free Operation: The integral seals and factory-applied grease lubrication protect against contamination and provide reliable operation within a temperature range of -30°C to 110°C, reducing maintenance needs.
