1210KJ Bearing Product Overview & Core Advantages
The 1210KJ metric double row angular contact ball bearing represents a high-performance solution for applications requiring superior radial load capacity and precise operation. Featuring a tapered bore design (1:12), this bearing delivers exceptional running accuracy and secure shaft mounting. Its double row construction provides high rigidity and is capable of handling significant combined loads. Manufactured from chrome steel and supplied pre-lubricated, it is engineered for reliable service in demanding industrial environments.
1210KJ Bearing Model Code Explained, Specifications & Naming Convention
| Model Segment | Technical Meaning |
|---|---|
| 1210 | Standard bearing series designation, indicating a bore diameter of 50 mm and specific cross-section. |
| K | Denotes a tapered bore with a 1:12 ratio, facilitating precise interference fits on adapter sleeves or withdrawal sleeves. |
| J | Indicates the steel cage construction, providing robust support for the balls at high speeds. |
1210KJ Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing design provides enhanced stiffness, enabling it to support substantial radial dynamic loads (5962 lbf) and resist operational deformation.
- Tapered Bore Advantage: The 1:12 taper allows for a precise and secure fit on the shaft, minimizing internal clearance and improving rotational accuracy.
- Optimized for Speed: The pressed steel cage (cage material: Steel) and balanced internal geometry contribute to a high limiting speed of 10,000 rpm.
- Ready for Service: The bearing is supplied pre-lubricated and features an open seal type, making it ready for immediate installation while allowing for customized re-lubrication regimes if required.
- Standard Internal Clearance: Supplied with a CN radial internal clearance, which is the standard group for normal operating conditions.
1210KJ Bearing Typical Application Areas
This bearing is ideally suited for machinery and systems requiring high precision and robust performance, including:
- Industrial Gearboxes and Transmissions
- Electric Motor Shafts
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery where high radial load capacity is critical
