| 305263 | Basic bearing designation, defining the core bearing dimensions (200mm bore, 289.5mm OD). |
| DA | Signifies a specific double row angular contact design with a defined contact angle, optimized for high axial and radial load capacity. |
305263 DA Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row design provides a significantly wider supporting surface than single row bearings, resulting in exceptional high rigidity and stability. This enables the bearing to handle substantial combined loads and moment loads effectively.
Optimized for Performance: The stainless steel cage ensures durability and reliable guidance of the balls, contributing to smooth operation. The bearing is supplied lubricated for immediate use, with a specified operating temperature range of -30°C to 110°C.
Precision Engineering: Manufactured to a P6 tolerance class, this bearing guarantees precise running accuracy and minimal vibration, which is critical for applications like machine tool spindles.
305263 DA Bearing Typical Application Areas
This bearing's combination of high load capacity, rigidity, and precision makes it suitable for a range of demanding industrial applications, including:
- Machine Tool Spindles
- Industrial Gearboxes
- Pumps and Compressors
- Precision Industrial Machinery
