1318J Bearing Product Overview & Core Advantages
The 1318J is a double row angular contact ball bearing designed for demanding industrial applications requiring high load capacity and rigidity. This precision bearing excels at simultaneously supporting substantial combined loads—both radial and axial forces—within a single, compact unit. Its open design and optimized internal geometry contribute to its high performance, making it an ideal choice for machinery where high rigidity and operational reliability are paramount.
1318J Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1318J | Standard bearing designation indicating specific bearing dimensions (90mm bore, 190mm OD). |
| Open (No Seal Suffix) | Bearing is supplied without integral seals or shields, allowing for higher speeds and custom lubrication solutions. |
| CN Radial Clearance | Specifies standard (normal) radial internal clearance, suitable for most common operating conditions. |
| Lubricated | Bearing is pre-lubricated from the factory, ensuring immediate operational readiness. |
1318J Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball complement and robust steel cage construction provide exceptional stiffness, enabling the bearing to handle significant combined loads without excessive deflection. This design is critical for maintaining precision in heavy-duty applications.
- Optimized for High-Speed Operation: With a limiting speed of 4,500 rpm, the bearing's internal geometry and cage design are engineered for stable performance at high rotational velocities.
- Superior Material Construction: Manufactured from chrome steel for both rings and balls, the bearing offers high wear resistance and long service life under demanding conditions.
- Pre-Configured for Service: The standard CN radial clearance and factory lubrication make the bearing ready for installation and operation, simplifying the procurement and maintenance process.
1318J Bearing Typical Application Areas
This bearing is commonly specified in:
- Industrial Gearboxes and power transmission systems
- Heavy-Duty Machinery requiring robust shaft support
- Material Handling Equipment such as conveyor pulleys
- Agricultural Machinery and construction equipment
- Pumps and medium-duty industrial fans
