7022 ACE/P4ADGB Bearing Product Overview & Core Advantages
The 7022 ACE/P4ADGB is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. As a Universal Matchable (SU) bearing supplied in a pre-lubricated, Light preload (Class B) set of two, it is engineered to handle combined loads efficiently, accommodating significant axial loads in one direction alongside radial loads. Its P4A tolerance class and phenolic cage contribute to its high-speed capabilities and stable performance in high-precision, high-rigidity applications such as machine tool spindles.

| DGB | Signifies a Universal Matchable (SU) bearing pair supplied with a Light preload (Class B). |
7022 ACE/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The 25° contact angle and robust construction enable the bearing to support high combined loads, providing exceptional system stability and rigidity.
- High-Speed Performance: The lightweight phenolic resin cage ensures lower centrifugal forces and excellent guidance, contributing to a high limiting speed of 16,250 rpm.
- Precision Operation: Manufactured to P4A tolerance class with tight dimensional tolerances on the bore, outside diameter, and width, guaranteeing smooth and precise rotation essential for precision machinery.
- Universal Matchability (SU): These bearings are universally matchable, allowing any two bearings to be mounted together in a back-to-back (DB), face-to-face (DF), or tandem (DT) arrangement without pre-selection, simplifying installation and inventory management.
- Pre-lubricated & Ready-to-Install: The bearing is pre-lubricated, ensuring immediate operational readiness and protecting against initial wear.
