7006 ACD/P4ATBTC Bearing Product Overview & Core Advantages
The 7006 ACD/P4ATBTC is a precision angular contact ball bearing designed for demanding applications requiring exceptional rigidity and accuracy. This triplex back-to-back matched set delivers superior performance in handling combined loads (radial and axial) simultaneously. Manufactured to P4A tolerance class, it ensures minimal runout and vibration, making it ideal for high-precision, high-stability machinery. The moderate preload (Class C) provides optimal stiffness while maintaining smooth operation.
7006 ACD/P4ATBTC Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| ACD | 25° Contact Angle, optimized for axial load capacity |
| P4A | High Precision Tolerance Class (superior to ABEC 7) |
| TBT | Triplex Back-to-Back matched arrangement for maximum rigidity |
7006 ACD/P4ATBTC Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The triplex back-to-back configuration creates an extremely rigid bearing system capable of withstanding heavy combined loads and moment loads. The 25° contact angle provides excellent axial load carrying capacity in both directions.
Precision Performance: Manufactured to P4A tolerance class with tight dimensional controls (bore: -0.004mm to 0, OD: -0.004mm to 0), ensuring minimal runout and vibration for high-speed applications.
High-Speed Capability: The phenolic cage offers excellent strength-to-weight ratio, contributing to the bearing's ability to reach limiting speeds of 53,000 rpm while maintaining stability.
Premium Material Construction: Made from chrome steel for both rings and balls, providing high durability, wear resistance, and consistent performance across the operating temperature range of -30°C to 110°C.
