S7006 CDGA/P4A Bearing Product Overview & Core Advantages
The S7006 CDGA/P4A is a high-precision angular contact ball bearing engineered for demanding applications requiring exceptional accuracy and performance. This single bearing features an extra light preload (Class A) and is manufactured to the stringent P4A tolerance class, ensuring minimal runout and superior rotational accuracy. Its primary advantage lies in its ability to handle combined loads—significant radial loads alongside thrust loads in one direction—making it an ideal, compact solution for high-speed spindles and other precision machinery where high rigidity and reliability are paramount.
S7006 CDGA/P4A Bearing Model Code Explained, Specifications & Naming Convention
The model number S7006 CDGA/P4A provides detailed technical specifications:
- S7006: Denotes the bearing series and size (30mm bore, 55mm OD, 13mm width).
- C: Signifies a 15° contact angle, optimized for high-speed operation.
- DG: Indicates a Universal Matchable (SU) bearing. It is one of a set of three bearings ground to be mounted in a universal arrangement (DB, DF, or DT).
- A: Specifies an Extra Light Preload (Class A), which minimizes friction and heat generation at high speeds.
- P4A: Represents the tolerance class, exceeding ABEC 7 precision with very tight dimensional and running accuracy tolerances.
S7006 CDGA/P4A Bearing Structural Features & Performance Benefits
- High Precision and Rigidity: Manufactured to P4A tolerance standards with a phenolic resin cage, this bearing ensures exceptional dimensional stability and smooth operation, contributing to superior system rigidity.
- Optimized for High-Speed Performance: The 15° contact angle and light preload are specifically designed to reduce heat buildup and power loss, enabling a high limiting speed of 100,500 rpm.
- Superior Load Capacity: The robust construction, using chrome steel for rings and balls, provides a high dynamic load rating of 3218 lbf, ensuring long service life under demanding combined load conditions.
- Sealed and Pre-Lubricated: As a sealed bearing pre-lubricated with grease, it is protected from contamination and is ready for immediate use, offering a maintenance-free solution within its specified temperature range of -30°C to 110°C.
S7006 CDGA/P4A Bearing Typical Application Areas
The S7006 CDGA/P4A is ideally suited for high-precision, high-speed applications, including:
- Machine Tool Spindles
- High-Frequency Motors
- Precision Grinding Equipment
- Medical and Dental Handpieces
- Aerospace Instrumentation
