S7011 CD/P4ATBTA Bearing Product Overview & Core Advantages
The S7011 CD/P4ATBTA is a high-precision angular contact ball bearing designed for demanding applications requiring exceptional accuracy and rigidity. This bearing is supplied as a matched triplex set in a back-to-back (TBT) arrangement, providing superior stability and load-handling capabilities. Its P4A tolerance class ensures extremely tight dimensional control, making it ideal for high-speed spindles and precision machinery where minimal runout and vibration are critical. The combination of extra light preload (Class A) and a 15° contact angle optimizes performance for applications involving combined radial and axial loads.
S7011 CD/P4ATBTA Bearing Model Code Explained, Specifications & Naming Convention
- S7011: Basic bearing series and size designation (55mm bore, 90mm OD, 54mm width)
- CD: Contact angle of 15°
- P4A: High-precision tolerance class exceeding ABEC 7 standards
- TBT: Triplex Back-to-Back matched set arrangement
- A: Extra light preload classification
S7011 CD/P4ATBTA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The triplex back-to-back configuration creates an extremely rigid bearing system capable of handling significant combined loads (radial and axial) from multiple directions. This arrangement provides excellent moment load resistance.
Precision Engineering: Manufactured to P4A tolerance class with bore and outside diameter tolerances of -0.004mm to 0, ensuring minimal vibration and precise rotational accuracy for high-speed applications.
Optimized Materials: Features chrome steel rings and balls for durability and fatigue resistance, combined with a phenolic cage that provides excellent strength-to-weight ratio and smooth operation at high speeds.
High-Speed Capability: With a limiting speed of 46,000 rpm and grease lubrication, this bearing is engineered for high-speed spindle applications while maintaining stable operation across a temperature range of -30°C to 110°C.
