S7014 ACD/P4ATBTB Bearing Product Overview & Core Advantages
The S7014 ACD/P4ATBTB is a super-precision angular contact ball bearing configured as a triplex back-to-back (TBT) matched set. Engineered for the most demanding applications, this bearing delivers exceptional rotational accuracy, high rigidity, and superior high-speed performance. Its matched TBT arrangement provides outstanding stability and is capable of supporting combined loads (radial and axial) from multiple directions simultaneously. The P4A tolerance class and phenolic cage make it an ideal solution for high-precision, high-reliability machinery.

S7014 ACD/P4ATBTB Bearing Structural Features & Performance Benefits
High Rigidity & Stability: The triplex back-to-back configuration creates an extremely rigid bearing system that minimizes deflection under load, making it ideal for applications requiring high positional accuracy.
Superior Load Capacity: With a dynamic load rating of 23,850 lbf and static load rating of 29,700 lbf, this bearing set handles significant combined radial and axial loads efficiently.
Optimized High-Speed Performance: The phenolic cage and precision manufacturing enable a limiting speed of 22,000 rpm, while the 25° contact angle provides excellent axial load capacity at high rotational speeds.
Precision Engineering: Manufactured to P4A tolerance class with tight dimensional controls (bore and OD tolerance: -0.004mm to 0), ensuring consistent performance and minimal runout.
Sealed & Lubricated: Factory-sealed and pre-lubricated with grease suitable for a temperature range of -30°C to 110°C, providing long-term protection and maintenance-free operation.
