S7016 CD/P4ATBTB Bearing Product Overview & Core Advantages
The S7016 CD/P4ATBTB is a precision angular contact ball bearing configured as a triplex back-to-back (TBT) matched set. Engineered for applications demanding exceptional rotational accuracy and rigidity, this pre-assembled set is designed to handle combined radial and axial loads simultaneously. Manufactured to P4A tolerance class and preloaded to Light / Class B, it delivers superior running precision and stability, making it ideal for high-speed, high-rigidity spindles and other precision machinery.

| Suffix Code | Technical Meaning |
|---|---|
| C | 15° contact angle |
| D | Modifications to internal bearing design |
| P4A | High precision tolerance class (equivalent to ABEC 7) |
| TBT | Triplex Back-to-Back matched set arrangement |
S7016 CD/P4ATBTB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The triplex back-to-back arrangement of three bearings creates an extremely rigid support system, capable of withstanding heavy combined loads and moment loads. The 15° contact angle is optimized for sustaining significant axial loads.
- High-Speed Performance: The phenolic cage offers low weight and excellent operational characteristics at high speeds, contributing to the bearing's limiting speed of 28,000 rpm. The set is pre-lubricated with grease suitable for this performance envelope.
- Precision & Accuracy: Manufactured to P4A tolerance class with tight dimensional tolerances on the bore, outside diameter, and width, ensuring minimal runout and superior positional accuracy in the application.
- Sealed & Pre-Lubricated: The sealed design protects the precision internals from contamination. Being pre-lubricated with grease, it is ready for immediate installation and operation within its specified temperature range of -30°C to 110°C.
S7016 CD/P4ATBTB Bearing Typical Application Areas
This precision triplex bearing set is specifically designed for high-performance applications, including:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Spindles: Applications in PCB drilling, precision grinding, and other high-accuracy machining.
- High-Frequency Motors: Spindles for routers and other high-RPM electric motors.
- Any machinery requiring a compact, pre-matched bearing set for high rigidity and exceptional running accuracy.
