|---|---|
| 7005 | Basic bearing series, indicating a 25 mm bore, 47 mm OD, and 24 mm width. |
| C | Specifies a 15° contact angle, optimized for high axial load capacity. |
| D | Indicates a duplex (two-bearing) set. |
| P4A | Denotes a high-precision tolerance class with enhanced running accuracy and dimensional stability. |
| DT | Signifies the Duplex Tandem arrangement, where two bearings are mounted together to increase axial load capacity in one direction. |
7005 CD/P4ADT Bearing Structural Features & Performance Benefits
High Rigidity & Axial Load Capacity: The duplex tandem arrangement and 15° contact angle are specifically designed to provide maximum stiffness and support for heavy axial loads in one direction, preventing shaft displacement under operation.
Precision & High-Speed Performance: Built to P4A tolerance standards and featuring a lightweight phenolic resin cage, this bearing achieves excellent rotational accuracy and is capable of operating at limiting speeds up to 103,000 rpm, making it suitable for high-speed applications.
Superior Material & Construction: The use of chrome steel for both rings and balls ensures high durability and wear resistance. The bearing is pre-lubricated, facilitating immediate installation and reliable operation within a temperature range of -30°C to 110°C.
