7026 CD/P4ATBTA Bearing Product Overview & Core Advantages
The 7026 CD/P4ATBTA is a metric precision angular contact ball bearing supplied as a triplex back-to-back (TBT) matched set. Engineered for the most demanding applications, this configuration delivers exceptional system rigidity and stability under complex loading conditions. Its P4A tolerance class ensures ultra-high running accuracy, making it ideal for high-precision spindles and machinery requiring superior rotational performance. The extra light preload (Class A) minimizes deflection and heat generation, contributing to extended service life and consistent accuracy.
7026 CD/P4ATBTA Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7026 | Standard bearing series designation (130mm bore, 200mm OD). |
| CD | Indicates a specific internal design and contact angle (15°). |
| P4A | Denotes a high-precision tolerance class exceeding ABEC 7 standards. |
| TBT | Specifies a Triplex Back-to-Back matched arrangement of three bearings. |
| A | Signifies an Extra Light Preload for minimal friction and optimal high-speed operation. |
7026 CD/P4ATBTA Bearing Structural Features & Performance Benefits
- Superior Rigidity & Load Capacity: The triplex back-to-back arrangement creates an extremely rigid bearing system capable of withstanding heavy combined loads (radial and axial) and significant overturning moments. This design provides unmatched stability for precision spindles.
- High-Speed Capability: The combination of a phenolic resin cage, a 15° contact angle, and extra light preload allows for a high limiting speed of 11,000 rpm. The phenolic cage offers excellent strength-to-weight ratio and operates smoothly at high velocities.
- Precision Performance: Manufactured to P4A tolerance class with tight dimensional control on bore, outside diameter, and width, this bearing ensures minimal runout and vibration for superior machining finish and positioning accuracy.
- Durability & Reliability: Constructed from high-grade chrome steel for both rings and balls, the bearing offers high fatigue life and wear resistance. The set is pre-lubricated for immediate operation.
