1318KJ Bearing Product Overview & Core Advantages
The 1318KJ is a double row angular contact ball bearing engineered for demanding applications requiring high rigidity and precision. Featuring a tapered bore (1:12), this metric bearing is designed to accommodate combined loads—significant radial forces alongside axial loads in both directions. Its double-row construction provides a compact, high-capacity solution, making it ideal for high-reliability machinery where space optimization and robust performance are critical. The bearing comes pre-lubricated and is manufactured from high-grade chrome steel for extended service life.
1318KJ Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning |
|---|---|
| K | Indicates a tapered bore with a 1:12 ratio. This design allows for precise axial positioning and secure mounting on an adapter sleeve or withdrawal sleeve. |
| J | Specifies the steel cage construction. This pressed steel cage offers high strength and is suitable for a wide range of operating conditions, contributing to the bearing's stability at high speeds. |
1318KJ Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design significantly increases radial and axial stiffness compared to single-row bearings. This enables the 1318KJ to handle substantial combined loads effectively, providing stable and precise shaft support.
- Optimized for High-Speed Operation: The pressed steel cage (J) ensures low friction and reliable performance at the specified limiting speed of 4,500 rpm. The CN radial internal clearance is the standard for normal operating conditions, balancing thermal expansion and preload requirements.
- Precision Tapered Bore: The 1:12 tapered bore facilitates easy and accurate mounting and dismounting on a shaft using standard adapter sleeves, ensuring a tight, slip-free fit for high-torque applications.
- Durability and Compliance: Manufactured from chrome steel for both rings and balls, the bearing offers excellent wear resistance and fatigue life. It is compliant with ROHS and REACH environmental standards.
1318KJ Bearing Typical Application Areas
This bearing is well-suited for industrial machinery requiring robust performance and high precision, including:
- Gearboxes and Drivetrain Systems
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural and Construction Machinery
- Vibrating Screens and other heavy-duty applications
