7312 BEGBM Bearing Product Overview & Core Advantages
The 7312 BEGBM is a single row angular contact ball bearing engineered for high-precision applications requiring exceptional performance under combined loads. This precision bearing features a 40° contact angle, enabling it to support significant radial loads and unidirectional axial loads simultaneously. Manufactured to P6 (ABEC-3) tolerance class, it delivers superior running accuracy and rotational stability. Its optimized internal geometry and brass cage construction make it suitable for high-speed operation up to 8,500 rpm, while its robust chrome steel construction ensures high rigidity and long service life in demanding industrial environments.
7312 BEGBM Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| BE | Increased internal radial clearance for specific thermal expansion requirements |
| GB | Contact angle of 40° for optimal axial load capacity |
| BM | Brass cage (machined) for enhanced high-speed performance and stability |
7312 BEGBM Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The single row angular contact design with 40° contact angle provides excellent resistance to combined radial and axial loads. With a radial dynamic load rating of 23,400 lbf and static load rating of 17,212 lbf, this bearing delivers reliable performance in heavy-duty applications.
High-Speed Capability: The precision-machined brass cage (BM) ensures optimal ball guidance and reduced friction, enabling limiting speeds of 8,500 rpm. The open design facilitates efficient lubrication and heat dissipation.
Precision Engineering: Manufactured to P6 tolerance class with tight dimensional controls (bore diameter: 60 mm, outside diameter: 130 mm, width: 31 mm), this bearing guarantees consistent performance and easy installation in precision machinery.
Material Excellence: Constructed from chrome steel for both rings and balls, providing superior hardness, wear resistance, and fatigue life. The bearing comes pre-lubricated and operates effectively within a temperature range of -30°C to 110°C.
