1316-KM C/3 Bearing Product Overview & Core Advantages
The 1316-KM C/3 is a metric double row angular contact ball bearing engineered for applications requiring exceptional rigidity and the ability to handle combined loads. Its double row design provides superior radial load capacity while simultaneously supporting significant axial loads in both directions. Featuring a 1:12 tapered bore for secure shaft mounting and manufactured from high-grade chrome steel, this bearing is built for precision and durability in demanding industrial environments. The CN radial internal clearance and brass cage contribute to stable operation and high-speed capability, making it a reliable choice for high-performance machinery.
1316-KM C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1316 | Standard bore diameter (80 mm) and outside diameter (170 mm) series. |
| KM | Indicates a tapered bore with a 1:12 ratio, designed for use with adapter sleeves for easy installation and disassembly. |
| C | Specifies the radial internal clearance group. "C" corresponds to a CN (Normal) clearance, suitable for most common operating conditions. |
| 3 | Denotes the bearing is lubricated from the factory, ensuring immediate operational readiness. |
1316-KM C/3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides significantly greater radial stiffness compared to single row designs. This enables the bearing to support substantial combined radial and axial loads simultaneously, making it ideal for applications with complex loading scenarios.
- Tapered Bore for Secure Mounting: The 1:12 tapered bore allows for precise and secure mounting on a tapered shaft seat or via an adapter sleeve. This design ensures a tight interference fit, eliminating inner ring creep and enhancing overall system stability.
- Optimized High-Speed Performance: The robust brass cage ensures precise guidance of the balls, reducing friction and wear at high rotational speeds. This contributes to a high limiting speed of 5,300 rpm.
- Precision Manufacturing & Material Quality: Manufactured from high-carbon chrome steel for both rings and balls, the bearing offers high hardness, wear resistance, and a long operational life. The dimensional tolerances (e.g., bore: -0.015mm to 0) ensure precise fits and reliable performance.
1316-KM C/3 Bearing Typical Application Areas
The 1316-KM C/3 is suited for a wide range of industrial machinery where high rigidity and combined load capacity are critical. Key application areas include:
- Gearboxes and Transmission Systems
