7008 ACEGA/P4AL Bearing Product Overview & Core Advantages
The 7008 ACEGA/P4AL is a high-precision angular contact ball bearing designed for applications demanding exceptional accuracy and rigidity. Manufactured to P4A tolerance class, it delivers superior running precision. Its 25° contact angle and Universal Matchable (SU) design enable it to handle combined radial and axial loads efficiently. Preloaded to Extra Light (Class A), this bearing is optimized for high-speed operation up to 41,000 rpm, making it an ideal choice for high-precision, high-rigidity spindle and machine tool applications.
7008 ACEGA/P4AL Bearing Model Code Explained, Specifications & Naming Convention
The model number 7008 ACEGA/P4AL is decoded as follows:
- 7008: Basic series designation, indicating a metric angular contact ball bearing with a 40mm bore and 68mm outside diameter.
- AC: Angular Contact design.
- E: Optimized internal design for high-speed performance.
- GA: Indicates a Universal Matchable (SU) bearing supplied in a set of two (Number of bearings in matched set: 2), preloaded against each other.
- P4A: Denotes a super-precision tolerance class with specific running accuracy requirements.
- L: Signifies the bearing is Lubricated from the factory.
7008 ACEGA/P4AL Bearing Structural Features & Performance Benefits
- High Rigidity and Precision: The bearing's construction to P4A tolerance standards ensures minimal runout and vibration, providing stable and precise rotational performance essential for machining accuracy.
- Superior Load Capacity: The 25° contact angle allows the bearing to support significant combined radial and axial loads simultaneously.
- Optimized High-Speed Performance: The combination of an optimized internal design (E) and a lightweight, durable Phenolic cage enables a high limiting speed of 41,000 rpm.
- Universal Matching: As a Universal Matchable (SU) bearing supplied in a preloaded pair (GA suffix), it simplifies installation and ensures optimal preload and stiffness in the application.
- Durable Material Construction: Manufactured from Chrome Steel for both rings and balls, ensuring high durability and a long service life.
