7408 BCBM Bearing Product Overview & Core Advantages
The 7408 BCBM is a precision angular contact ball bearing designed for applications requiring exceptional rotational accuracy and high-speed performance. Engineered with a 40° contact angle and manufactured to P6 (ABEC-3) tolerance class, this single-row bearing excels at supporting combined loads, handling significant axial loads in one direction alongside radial loads. Its open design facilitates optimal lubrication management and allows for higher limiting speeds, making it an ideal choice for high-reliability, high-performance machinery where rigidity and precision are paramount.
7408 BCBM Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 7408 | Standard bearing series designation indicating a 40mm bore, 110mm OD, and 27mm width. |
| BCBM | Manufacturer-specific code indicating a brass cage and lubricated configuration for enhanced high-speed stability and durability. |
7408 BCBM Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The optimized 40° contact angle and robust single-row design provide superior stiffness, enabling the bearing to effectively support combined radial and axial loads. With a dynamic load rating of 15,795 lbf and a static load rating of 10,125 lbf, it delivers reliable performance under demanding conditions.
- High-Speed Performance: The brass cage (Cage material: Brass) ensures exceptional dimensional stability and low friction at high rotational speeds, contributing to the high limiting speed of 11,000 rpm.
- Precision Engineering: Manufactured to P6 (ABEC-3) tolerance class with tight dimensional tolerances on the bore, outside diameter, and width, this bearing guarantees precise shaft positioning and smooth operation in precision applications.
- Material & Durability: Constructed from chrome steel for both rings and balls, the bearing offers high wear resistance and long service life. It is pre-lubricated for immediate use and operates effectively within a temperature range of -30°C to 110°C.
7408 BCBM Bearing Typical Application Areas
This angular contact ball bearing is ideally suited for high-speed and high-precision applications, including:
- Machine Tool Spindles
- High-Speed Pumps & Compressors
- Precision Gearboxes
- Industrial Robotics and Automation Equipment
- Medical and Laboratory Instrumentation
