|---|---|
| S7 | Series designation for high-precision angular contact ball bearings. |
| 1922 | Bore diameter: 110 mm, Outside diameter: 150 mm, Width: 40 mm. |
| CD | A 15° contact angle and specific internal design optimized for high-speed operation and high rigidity. |
| P4A | Indicates an ABEC 7 / ISO P4A super-precision tolerance class for exceptional running accuracy. |
| DGB | Signifies a universal matchable (SU) pair of bearings supplied with a light preload (Class B). |
S71922 CD/P4ADGB Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row angular contact design and universal matching create a highly rigid bearing system capable of handling significant combined radial and axial loads from both directions.
- Precision & High-Speed Performance: The P4A tolerance class and 15° contact angle are engineered for minimal runout and smooth operation at high speeds. The lightweight phenolic cage contributes to lower inertia and a higher limiting speed.
- Optimized for Longevity: Manufactured from chrome steel for both rings and balls, this bearing offers high durability and wear resistance. It comes pre-lubricated with grease suitable for a wide temperature range.
- Sealed Design: As a sealed bearing, it is protected from contamination, preserving lubricant integrity and extending service life in challenging environments.
S71922 CD/P4ADGB Bearing Typical Application Areas
This high-precision, high-rigidity bearing is ideally suited for:
- Machine Tool Spindles: High-speed milling, grinding, and turning centers.
- Precision Instrumentation: Measuring devices and high-accuracy rotary tables.
- High-Frequency Motors & Spindles: Where low vibration and high running accuracy are critical.
- Industrial Pumps and Compressors: Applications demanding reliable performance under combined loads.
