S7010 CDGA/P4A Bearing Product Overview & Core Advantages
The S7010 CDGA/P4A is a high-precision angular contact ball bearing designed for exceptional performance in demanding applications. As a single-row bearing with an extra light preload (Class A), it delivers high running accuracy and minimal heat generation. Its primary advantage lies in its ability to accommodate combined radial and axial loads simultaneously, making it an ideal choice for high-speed spindles and other precision machinery where rigidity and rotational accuracy are paramount. The bearing is manufactured to a P4A tolerance class, ensuring superior dimensional and running accuracy for critical applications.
S7010 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| S7010 | Basic bearing series and size designation (50mm bore, 80mm OD). |
| C | 15° nominal contact angle, optimized for high-speed performance. |
| DG | Universal Matchable (SU) bearing. Two bearings can be mounted in a face-to-face (DF) or back-to-back (DB) arrangement without selective mounting. |
| A | Signifies extra light preload (Class A), which minimizes friction and heat for higher limiting speeds. |
| P4A | Indicates a high-precision tolerance class superior to ABEC-7, ensuring extremely tight dimensional and running accuracy. |
S7010 CDGA/P4A Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a 15° contact angle, phenolic resin cage, and extra light preload enables a very high limiting speed of 46,000 rpm, making it suitable for high-speed spindle applications.
- Superior Rigidity and Accuracy: Manufactured to P4A precision tolerances with a preload, this bearing provides high system rigidity and excellent running accuracy, which is critical for machining precision.
- Optimized Load Capacity: The design effectively handles combined radial and axial loads, with a dynamic load rating of 6660 lbf and a static load rating of 5400 lbf.
- Universal Matching: The DG designation allows for simplified mounting of bearing pairs (in sets of 3) in any configuration (DB or DF) to achieve the required stiffness and load distribution without selective assembly.
- Premium Materials: Constructed from chrome steel for rings and balls, ensuring high durability and long service life under demanding conditions.
