S7002 ACE/P4ATFTA Bearing Product Overview & Core Advantages
The S7002 ACE/P4ATFTA is a super-precision angular contact ball bearing designed for the most demanding applications. As part of a matched triplex set in a Face-to-Face (TFT) arrangement, it delivers exceptional system rigidity and rotational accuracy. Its P4A tolerance class and Extra Light (Class A) preload ensure smooth, high-speed operation with minimal runout, making it ideal for machine tool spindles and other high-performance machinery requiring uncompromising precision and reliability.
S7002 ACE/P4ATFTA Bearing Model Code Explained, Specifications & Naming Convention
The model number S7002 ACE/P4ATFTA provides a complete technical specification:
- S70: Indicates a series of high-precision, 15° contact angle bearings (Note: Specified contact angle is 25°).
- 02: Denotes a bore diameter of 15 mm (02 x 5 = 10 mm, common for this series; verify with manufacturer datasheet).
- ACE: Signifies a triplex set in a Face-to-Face (TFT) arrangement with Extra Light (Class A) preload.
- P4A: Defines the tolerance class, specifying extremely tight dimensional and running accuracy standards.
- TFT: Confirms the Triplex Face-to-Face matched arrangement of the three bearings.
- A: Specifies the Extra Light preload level within the set.
S7002 ACE/P4ATFTA Bearing Structural Features & Performance Benefits
- Ultra-High Rigidity & Load Capacity: The matched triplex set in a Face-to-Face configuration creates an exceptionally rigid bearing system, capable of supporting significant combined loads (radial and axial) from both directions.
- Super-Precision & High-Speed Performance: Manufactured to P4A tolerance standards and featuring a lightweight phenolic cage, this bearing achieves very high limiting speeds (95,000 rpm) with superior rotational accuracy and low heat generation.
- Optimized for Critical Applications: The 25° contact angle provides an excellent balance between radial and axial load capacity. The standard grease lubrication and sealed design offer reliable, long-term performance.
- Premium Materials: Constructed from chrome steel for rings and balls, ensuring high durability and fatigue resistance under demanding operating conditions.
S7002 ACE/P4ATFTA Bearing Typical Application Areas
This bearing is engineered for high-precision, high-speed machinery, including:
- Machine Tool Spindles: For CNC machining centers, grinding spindles, and lathes.
- High-Frequency Motors: Used in spindles for PCB drilling and other precision manufacturing.
- Precision Instrumentation: Critical components in measuring devices and optical scanners.
- Robotics: High-accuracy joints and arm assemblies.
