1215J Bearing Product Overview & Core Advantages
The 1215J is a double row angular contact ball bearing designed for applications requiring robust performance under combined loads. This precision bearing features an open design and is pre-lubricated, enabling it to handle significant radial loads and moderate axial loads in both directions simultaneously. Its compact construction, defined by a 75 mm bore and 130 mm outside diameter, offers a high degree of rigidity, making it an ideal choice for machinery demanding high reliability and operational stability.
1215J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1215 | Standard bearing series designation, indicating the bearing dimensions (75mm bore, 130mm OD, 25mm width). |
| J | Suffix indicating a CN (Normal) group of radial internal clearance. |
1215J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball construction provides superior rigidity and enables the bearing to support substantial radial dynamic load ratings of 8775 lbf and combined loads.
- Optimized for Performance: The pressed steel cage ensures stable operation at the limiting speed of 6,700 rpm. The CN radial internal clearance is suited for a wide range of common operating conditions.
- Material Integrity: Manufactured from chrome steel for both rings and balls, the bearing offers high durability and resistance to wear.
- Ready for Service: The bearing is pre-lubricated and features an open seal type, allowing for easy re-lubrication in service to maintain performance across its operating temperature range of -30°C to 110°C.
1215J Bearing Typical Application Areas
This bearing is commonly specified in industrial machinery where reliability under load is critical. Key applications include:
- Industrial Gearboxes
- Material Handling Conveyors
- Agricultural Machinery
- General Industrial Machinery requiring robust double row support
