S7007 ACDGB/HCP4A Bearing Product Overview & Core Advantages
The S7007 ACDGB/HCP4A is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional rotational accuracy and rigidity. As a universal matchable bearing supplied in sets of four, it enables the creation of optimized, pre-loaded bearing arrangements. Its core advantages include the ability to handle combined loads (radial and axial) simultaneously, superior high-speed performance facilitated by its phenolic cage and ceramic balls, and outstanding operational reliability due to its sealed design and P4A tolerance class.
S7007 ACDGB/HCP4A Bearing Model Code Explained, Specifications & Naming Convention
- S7007: Basic model number denoting a metric series, 35mm bore angular contact ball bearing.
- ACD: Angular Contact Design with a 25° contact angle.
- GB: Indicates a Light preload (Class B).
- HCP4A: Denotes the Universal Matchable (SU) set with a P4A tolerance class for extreme dimensional and running accuracy.
S7007 ACDGB/HCP4A Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The bearing's angular contact design and 25° contact angle provide high rigidity, enabling it to support significant combined radial and axial loads.
Superior High-Speed Performance: The combination of a lightweight phenolic resin cage and low-density ceramic balls significantly reduces centrifugal forces, allowing for a high limiting speed of 41,000 rpm.
Precision and Longevity: Manufactured to P4A tolerance class, this bearing ensures minimal runout and vibration. The sealed design with pre-applied grease lubrication protects against contamination and provides maintenance-free operation within a wide temperature range.
S7007 ACDGB/HCP4A Bearing Typical Application Areas
