V7013 ACEGA/P4A Bearing Product Overview & Core Advantages
The V7013 ACEGA/P4A is a single row angular contact ball bearing designed for applications demanding high precision and superior running accuracy. Manufactured to P4A tolerance class, this bearing is characterized by its extra light preload (Class A) and 25° contact angle, making it exceptionally suitable for high-speed spindles and other precision machinery where minimal deflection and high rotational accuracy are critical. Its universal matchable (SU) design allows for flexible mounting arrangements in pairs to handle combined radial and axial loads efficiently.
V7013 ACEGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACEGA | Designates a 25° contact angle and Extra Light (Class A) preload. This specific internal design optimizes the bearing for high-speed operation while maintaining stiffness. |
| P4A | Indicates a high-precision tolerance class with tighter controls on bore, outside diameter, and width dimensions, ensuring superior running accuracy and performance consistency. |
V7013 ACEGA/P4A Bearing Structural Features & Performance Benefits
- High Precision & Rigidity: The single row design with a 25° contact angle and extra light preload provides excellent rotational accuracy and rigidity, minimizing axial and radial runout under operational loads.
- Superior High-Speed Capability: The phenolic resin cage is lightweight and robust, contributing to lower centrifugal forces and enabling a high limiting speed of 36,000 rpm. The open design facilitates efficient lubrication management.
- Optimized Load Capacity: Engineered to handle significant combined loads (radial and axial). With a dynamic load rating of 4388 lbf and a static load rating of 3285 lbf, it offers reliable performance in demanding applications.
- Precision Materials: Constructed from chrome steel for both rings and balls, ensuring high hardness, durability, and long service life under high-stress conditions.
