7304 BECBM Bearing Product Overview & Core Advantages
The 7304 BECBM is a single row angular contact ball bearing engineered for applications demanding high precision and reliable performance under combined loads. Its defining feature is the 40° contact angle, which provides superior axial load carrying capacity in one direction while accommodating significant radial loads. Manufactured to P6 (ABEC-3) tolerance class, this bearing ensures precise running accuracy and is pre-lubricated for immediate use, making it an ideal solution for high-speed and high-rigidity applications where space is limited.
7304 BECBM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7304 | Basic bearing designation, indicating a metric angular contact ball bearing with a 20mm bore and 52mm outside diameter. |
| BE | Designates a 40° contact angle, optimized for high axial load capacity. |
| CBM | Indicates a brass cage and specific internal design optimizations for enhanced performance and guidance. |
7304 BECBM Bearing Structural Features & Performance Benefits
- High Rigidity and Load Capacity: The single row design with a 40° contact angle is engineered to handle significant combined loads (radial and axial), providing stable and rigid support for shafts.
- Optimized for High-Speed Operation: The use of a durable brass cage (CBM) ensures reliable performance at the limiting speed of 22,000 rpm, maintaining ball guidance and structural integrity under centrifugal forces.
- Precision Engineering: Manufactured to P6 tolerance class, this bearing guarantees minimal running vibration and high rotational accuracy, which is critical for precision machinery.
- Superior Material Construction: Components made from chrome steel for rings and balls offer high wear resistance and durability, ensuring a long service life under demanding conditions.
