305262 D Bearing Product Overview & Core Advantages
The 305262 D is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. This precision bearing excels at handling combined loads, simultaneously supporting substantial radial loads and axial loads in both directions. Its robust double-row construction provides exceptional stiffness, making it ideal for machinery where shaft deflection must be minimized. Manufactured to a P6 (ABEC-3) tolerance class and pre-lubricated, it offers reliable performance and long service life in demanding industrial environments.
305262 D Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 305262 | Basic bearing designation indicating the bearing size and series (180mm bore, 259.5mm OD). |
| D | Signifies a double row angular contact ball bearing construction. |
305262 D Bearing Structural Features & Performance Benefits
- High Rigidity: The double row design provides a significantly wider effective load spread than single row bearings, resulting in superior shaft support and system stiffness.
- Combined Load Capacity: Engineered with a specific contact angle, this bearing is optimized to carry heavy radial loads and bidirectional axial loads simultaneously.
- Precision & Speed: Built to P6 tolerance for precise running accuracy. The stainless steel cage ensures stability and contributes to a high limiting speed of 2,600 rpm.
- Durability & Reliability: Components made from chrome steel offer high load ratings (Cr: 50,625 lbf, C0r: 69,750 lbf) and excellent wear resistance. The open design with pre-lubrication facilitates easy maintenance and re-lubrication.
305262 D Bearing Typical Application Areas
This bearing is well-suited for heavy-duty and precision applications, including:
- Industrial Gearboxes and Power Transmission Systems
- Machine Tool Spindles and Precision Rotary Tables
- Large Pumps and Compressors
- Material Handling Equipment and Crane Hooks
- Other machinery requiring robust support for combination loads.
