1210K Bearing Product Overview & Core Advantages
The 1210K metric ball bearing is a double row angular contact ball bearing designed for exceptional performance in demanding applications. Its core advantage lies in its ability to support significant combined loads—handling both radial and axial forces simultaneously with high precision. Featuring a tapered bore (1:12) for precise shaft fitting and a robust double row construction, this bearing delivers superior rigidity and stability. Manufactured from high-grade chrome steel and utilizing a lightweight nylon cage, it is engineered for reliable operation in high-speed scenarios, making it an ideal precision bearing for industrial machinery.
1210K Bearing Model Code Explained, Specifications & Naming Convention
| Suffix / Prefix | Technical Meaning |
|---|---|
| 1210 | Standard bore diameter code (50 mm) and dimension series. |
| K | Indicates a tapered bore with a 1:12 ratio, enabling precise interference fits on adapter sleeves or withdrawal sleeves for secure mounting. |
1210K Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement provides superior rigidity and enables the bearing to handle substantial radial dynamic loads (5962 lbf) and static loads (2059 lbf), as well as bidirectional axial loads.
- Optimized High-Speed Performance: The lightweight nylon cage minimizes centrifugal forces, reduces friction, and contributes to a high limiting speed of 10,000 rpm. The standard CN radial internal clearance is suited for most high-speed applications.
- Precision & Reliability: Manufactured from high-quality chrome steel for both rings and balls, ensuring durability and long service life. The open seal type allows for easy re-lubrication and is suitable for applications where custom sealing or frequent maintenance is planned.
- Pre- Lubricated & Ready for Use: The bearing comes lubricated from the factory, ensuring immediate operational readiness and protection during the initial run-in period.
1210K Bearing Typical Application Areas
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Any application requiring a robust, high-speed bearing with a tapered bore for secure shaft location.
