S7005 CDTP/P4B Bearing Product Overview & Core Advantages
The S7005 CDTP/P4B is a precision angular contact ball bearing designed for applications demanding exceptional rotational accuracy and rigidity. This single-row bearing features a 15° contact angle and is supplied with a preload, making it ideal for handling combined radial and axial loads simultaneously. Manufactured to a P4 (ABEC-7) tolerance class, it ensures superior running precision and is pre-lubricated for immediate use in high-speed and high-reliability machinery.

| Code Segment | Technical Meaning |
|---|---|
| S7005 | Standard bearing series designation with 25mm bore diameter. |
| C | Specific internal design and 15° contact angle. |
| DT | Matched set of two bearings for duplex mounting. |
| P | Application of a preload to increase system rigidity. |
| P4B | High precision tolerance class (equivalent to ABEC-7). |
S7005 CDTP/P4B Bearing Structural Features & Performance Benefits
High Rigidity and Precision: The phenolic resin cage, combined with the P4 tolerance class and applied preload, ensures minimal deflection and exceptional running accuracy, providing a stable and rigid rotational axis.
Superior Load Capacity: The 15° contact angle is optimized to support significant combined loads, efficiently managing both radial forces and thrust loads in one direction.
Optimized High-Speed Performance: The lightweight phenolic cage reduces centrifugal forces, contributing to a high limiting speed of 36,000 rpm. The bearing is pre-lubricated to ensure reliable operation at these elevated speeds.
Sealed and Lubricated for Longevity: As a sealed bearing, it is protected from contamination. The factory-applied lubrication ensures long-term, maintenance-free operation within the specified temperature range.
