| P4A | Tolerance Class | Denotes very high precision bearing standards for dimensional and running accuracy. |
| TBT | Triplex Back-to-Back | A matched set of three bearings arranged back-to-back, providing maximum rigidity and moment load capacity. |
| A | Preload: Extra Light | Ensures minimal deflection and smooth operation under light loads, ideal for high-speed, high-precision scenarios. |
7013 CE/HCP4ATBTA Bearing Structural Features & Performance Benefits
- Exceptional Rigidity and Load Capacity: The triplex back-to-back (TBT) arrangement of three bearings creates an extremely stiff bearing system capable of withstanding heavy combined loads and significant moment loads, which is critical for maintaining precision in machine tool applications.
- Superior High-Speed Performance: The combination of lightweight ceramic balls and a phenolic resin cage significantly reduces centrifugal forces and friction, enabling a high limiting speed of 31,000 rpm. The 15° contact angle is optimized for such high rotational velocities.
- Precision and Accuracy: Manufactured to P4A tolerance class, this bearing set guarantees ultra-precise dimensions and minimal runout, ensuring smooth, vibration-free operation essential for high-quality machining and finishing.
- Optimized for Performance: The open seal type allows for optimal lubrication flow and heat dissipation in controlled environments, while the extra light preload (Class A) minimizes friction and heat generation at high speeds.
