S7013 ACD/P4ADGB Bearing Product Overview & Core Advantages
The S7013 ACD/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional accuracy and reliability. Operating under the stringent P4A tolerance class, this bearing is engineered to handle combined radial and axial loads simultaneously. Its universal matchable (SU) design allows for flexible mounting arrangements in pairs, providing high system rigidity. Pre-loaded with light preload (Class B) and factory-lubricated with grease, it offers optimized performance for high-speed operation and long service life in demanding environments.
S7013 ACD/P4ADGB Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7013 | Basic bearing series, indicating a 65mm bore, 100mm OD, and 36mm width. |
| ACD | Contact angle of 25° and universal matchable (SU) design. |
| P4A | High precision tolerance class, exceeding ABEC 7 standards. |
| DGB | Sealed on both sides and pre-lubricated with grease. |
S7013 ACD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The angular contact design with a 25° contact angle and dual bearing arrangement provides superior stiffness, enabling it to withstand significant combined loads (radial dynamic load: 14,332 lbf, static: 15,975 lbf).
- Precision Performance: Manufactured to P4A tolerance class with tight dimensional control (bore/OD tolerance: -0.004mm to 0), ensuring minimal runout and vibration for high-precision applications.
- Optimized High-Speed Operation: The phenolic resin cage reduces friction and weight, contributing to a high limiting speed of 31,000 rpm. The grease lubrication is formulated for stable performance across the operating temperature range.
- Sealed & Maintenance-Friendly: Integrated seals protect against contamination, while the pre-applied grease offers long-term, maintenance-free operation within the specified temperature range (-30°C to 110°C).
