7212 BEP Bearing Product Overview & Core Advantages
The 7212 BEP is a single row angular contact ball bearing engineered for applications demanding high precision and reliable performance under combined loads. Featuring a 40° contact angle and manufactured to P6 (ABEC-3) tolerance class, this bearing is optimized to handle significant axial loads in one direction simultaneously with radial loads. Its compact design, with a bore of 60 mm and outside diameter of 110 mm, makes it an ideal solution for space-constrained, high-speed applications such as machine tool spindles. The bearing comes pre-lubricated for immediate use and offers a wide operating temperature range from -30°C to 110°C.
7212 BEP Bearing Model Code Explained, Specifications & Naming Convention
| Suffix | Technical Meaning |
|---|---|
| BE | Designates an increased internal clearance and 40° contact angle, optimized for high-speed operation and precise preload settings. |
| P | Indicates the bearing is manufactured to P6 tolerance class (equivalent to ABEC-3), ensuring high running accuracy and dimensional stability. |
7212 BEP Bearing Structural Features & Performance Benefits
- High-Speed Capability: The combination of a nylon cage and optimized internal geometry, including the 40° contact angle, enables a high limiting speed of 7,000 rpm, reducing centrifugal forces and heat generation.
- Superior Load Capacity: The angular contact design efficiently supports combined radial and substantial one-direction axial loads, with a dynamic load rating of 12,870 lbf and static load rating of 10,238 lbf.
- Precision & Rigidity: Manufactured to P6 precision class with tight dimensional tolerances, this bearing provides high running accuracy and system rigidity, crucial for applications like precision spindles.
- Ready-to-Use Lubrication: The bearing is supplied pre-lubricated, facilitating easy installation and ensuring immediate, reliable operation.
