S7012 CDGC/P4A Bearing Product Overview & Core Advantages
The S7012 CDGC/P4A is a precision angular contact ball bearing engineered for applications demanding exceptional rotational accuracy and rigidity. Operating under the P4A tolerance class, this bearing is designed to handle combined loads efficiently, supporting significant radial loads and axial loads in one direction. Its compact design, featuring a single matched arrangement with a 15° contact angle and moderate preload (Class C), ensures high running accuracy and stability, making it ideal for high-speed, high-reliability machinery where precision is paramount.
S7012 CDGC/P4A Bearing Model Code Explained, Specifications & Naming Convention
- S7012: Basic model number denoting a 60 mm bore, 95 mm OD, and 18 mm width.
- C: Represents a 15° contact angle.
- DG: Indicates a Universal Matchable (SU) bearing, supplied as part of a matched set of 2 bearings for optimized performance.
- C: Specifies a Moderate Preload (Class C).
- P4A: Denotes an ultra-precision tolerance class exceeding ABEC 7 standards, ensuring minimal runout and superior dimensional stability.
S7012 CDGC/P4A Bearing Structural Features & Performance Benefits
High Rigidity and Load Capacity: The optimized internal geometry, combined with the 15° contact angle and moderate preload, provides high system rigidity and excellent capability for handling combined radial and axial loads.
High-Speed Performance: The use of a lightweight, durable phenolic resin cage and precision-ground chrome steel components allows for a high limiting speed of 36,000 rpm, making it a true high-speed bearing.
Precision and Longevity: Manufactured to P4A tolerance class with a bore and OD tolerance of -0.004mm to 0, this bearing guarantees exceptional running accuracy. The sealed design with factory-applied grease lubrication protects against contamination and provides reliable operation within a temperature range of -30°C to 110°C.
