7240 BCBM Bearing Product Overview & Core Advantages
The 7240 BCBM is a single row angular contact ball bearing designed for high-precision applications requiring exceptional performance under combined loads. Engineered with P6 (ABEC-3) tolerance class precision, it delivers superior running accuracy and rotational stability. Its defining characteristic is the 40° contact angle, which is optimized to handle significant axial loads in one direction simultaneously with radial loads. Constructed from high-grade chrome steel and featuring a durable brass cage, this bearing is built for reliability in demanding operational environments.
7240 BCBM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7240 | Basic bearing designation indicating a metric series angular contact ball bearing with a 200 mm bore and 360 mm outside diameter. |
| B | Signifies a 40° contact angle, which provides a high thrust capacity. |
| C | Indicates the internal design and clearance are optimized for the specified performance. |
| BM | Denotes that the bearing is lubricated and ready for operation. |
7240 BCBM Bearing Structural Features & Performance Benefits
- High Load Capacity & Rigidity: The single row design with a 40° contact angle is engineered to support high radial dynamic load ratings of 73,125 lbf and radial static load ratings of 96,750 lbf, providing excellent rigidity for precise shaft positioning.
- Optimized for Combined Loads: The angular contact geometry is specifically designed to handle combined radial and axial loads efficiently, making it ideal for applications with complex loading conditions.
- Precision & Speed Performance: Manufactured to a P6 (ABEC-3) tolerance class, it ensures high running accuracy. The robust brass cage contributes to stable operation at the specified limiting speed of 2,400 rpm.
- Ready-to-Use & Durable: The bearing comes pre-lubricated and features an open design, suitable for integration into systems with centralized lubrication. The use of high-quality chrome steel for rings and balls ensures long service life and resistance to wear.
