7407 BCBM Bearing Product Overview & Core Advantages
The 7407 BCBM is a single row angular contact ball bearing engineered for high-precision applications requiring superior performance under combined loads. This metric bearing is designed to accommodate significant axial loads in one direction in addition to radial loads, thanks to its defined 40° contact angle. Manufactured to a P6 (ABEC-3) tolerance class, it ensures high running accuracy and rotational stability. Its open design, combined with a robust brass cage, makes it an excellent choice for high-speed operation and demanding industrial environments where reliability is paramount.
7407 BCBM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7407 | Standard bearing series designation indicating the bearing dimensions (35mm bore, 100mm OD, 25mm width). |
| B | Signifies a 40° contact angle, which provides a high thrust capacity and rigidity. |
| C | Indicates the bearing is manufactured to normal internal clearance standards. |
| BM | Denotes that the bearing is lubricated with a high-quality grease suitable for the specified temperature range. |
7407 BCBM Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is optimized to handle high radial and one-direction axial loads simultaneously. The optimized internal geometry, including specific shoulder diameters, ensures stable operation under combined loads.
- Superior High-Speed Performance: The precision-machined brass cage provides excellent guidance and stability for the balls, contributing to smooth operation at the limiting speed of 12,000 rpm. The open design minimizes friction and heat generation.
- Precision Engineering: Manufactured to P6 tolerance class, this bearing guarantees high running accuracy and minimal vibration, which is critical for precision machinery.
- Durability and Material Quality: Constructed from chrome steel for both rings and balls, the bearing offers high fatigue resistance and long service life. The pre-applied lubrication ensures immediate readiness for operation.
7407 BCBM Bearing Typical Application Areas
