7238 BCBM Bearing Product Overview & Core Advantages
The 7238 BCBM is a single row angular contact ball bearing engineered for high-performance applications requiring exceptional precision and reliability. This precision bearing is designed to accommodate high combined loads, specifically significant axial loads in one direction alongside radial loads, thanks to its defined 40° contact angle. Manufactured to a P6 (ABEC-3) tolerance class, it ensures superior running accuracy, making it ideal for demanding industrial machinery where high rigidity and operational stability are paramount.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 7238 | Standard bearing series designation, defining the bearing dimensions (190mm bore, 340mm OD, 55mm width). |
| B | Indicates a 40° contact angle, optimized for handling high axial loads. |
| C | Specifies the internal design and cage material, in this case a brass cage for robust performance. |
| BM | Signifies that the bearing is lubricated and ready for immediate use upon installation. |
7238 BCBM Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row angular contact design, combined with a 40° contact angle and a sturdy brass cage, provides excellent high rigidity and enables the bearing to support substantial combined loads, with a radial dynamic load rating of 69,075 lbf and a static rating of 91,125 lbf.
- Optimized for Precision: Manufactured to a P6 tolerance class, this bearing guarantees minimal runout and vibration, which is critical for the smooth operation of high-speed and precision equipment.
- Ready-to-Install Convenience: The bearing comes lubricated from the factory, simplifying the installation process and ensuring immediate, reliable performance.
- Robust Material Construction: Components made from chrome steel for rings and balls offer high wear resistance and durability, suitable for a wide temperature range of -30°C to 110°C.
