7334 BCBM Bearing Product Overview & Core Advantages
The 7334 BCBM is a single row angular contact ball bearing engineered for applications requiring high precision and superior performance under combined loads. This metric bearing features a 40° contact angle, optimized to handle significant axial loads in one direction while simultaneously supporting radial loads. Manufactured to P6 (ABEC-3) tolerance class, it ensures exceptional running accuracy and rotational stability. Its robust construction from chrome steel and a brass cage provides reliable operation in demanding environments, making it an ideal choice for high-rigidity, high-speed applications.
7334 BCBM Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 7334 | Standard bearing series designation, indicating a 170 mm bore, 360 mm outside diameter, and 72 mm width. |
| BC | Indicates a 40° contact angle, optimized for high axial load capacity. |
| BM | Signifies the bearing is pre-lubricated from the factory for immediate use. |
7334 BCBM Bearing Structural Features & Performance Benefits
- Optimized Contact Angle & High Rigidity: The 40° contact angle is engineered to provide superior resistance to axial loads, while the single-row design with precision-ground raceways ensures high system rigidity and minimal deflection under load.
- Superior Load Capacity: With a dynamic load rating of 87,750 lbf and a static load rating of 110,250 lbf, this bearing is built to handle significant combined radial and axial loads.
- High-Speed Performance: The brass cage (machined window-type) provides excellent strength and guidance at high rotational speeds, contributing to a limiting speed of 2,600 rpm.
- Precision & Reliability: Manufactured to P6 (ABEC-3) tolerance class with tight dimensional control on bore, outside diameter, and width, ensuring precise fitment and smooth, quiet operation.
- Robust Material Construction: Rings and balls made from high-grade chrome steel offer high wear resistance and durability, suitable for a temperature range of -30°C to 110°C.
