| Suffix Code | Technical Meaning |
|---|---|
| AC | Angular Contact design with a 25° contact angle |
| D | Duplex Back-to-Back (DB) arrangement |
| P4A | High precision tolerance class for superior running accuracy |
| DB | Matched set designation for back-to-back mounting |
| A | Indicates Extra Light preload for minimal friction and high-speed capability |
7024 ACD/P4ADBA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The duplex back-to-back configuration creates a rigid bearing system that effectively resists moment loads and provides stable support for shafts. With a radial dynamic load rating of 40,050 lbf and static load rating of 52,200 lbf, this bearing excels in handling combined loads in demanding applications.
Precision Performance: Manufactured to P4A tolerance standards with tight dimensional control (bore and OD tolerance: -0.004mm to 0), this bearing ensures minimal runout and vibration. The 25° contact angle optimizes axial load carrying capacity while maintaining excellent radial load performance.
High-Speed Capability: The phenolic cage material and optimized internal design contribute to a limiting speed of 16,000 rpm, making it suitable for high-speed spindle applications. The open design allows for efficient lubrication management in high-speed environments.
Premium Material Construction: Both rings and balls are manufactured from chrome steel, providing excellent wear resistance and durability. The bearing comes pre-lubricated and operates effectively within a temperature range of -30°C to 110°C.
