1316 KC3 Bearing Product Overview & Core Advantages
The 1316 KC3 is a metric double row angular contact ball bearing engineered for demanding industrial applications requiring high radial load capacity and precision operation. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing delivers exceptional rigidity and stability under significant radial forces. Its open design allows for optimal lubrication management, while the C3 radial internal clearance accommodates thermal expansion in high-speed or high-temperature environments. Constructed from high-grade chrome steel and featuring a lightweight nylon cage, the 1316 KC3 offers a robust solution for applications where high dynamic load ratings and reliable performance are critical.
1316 KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1316 | Standard bearing designation indicating a metric double row angular contact ball bearing with an 80mm bore, 170mm OD, and 39mm width. |
| K | Denotes a tapered bore with a 1:12 taper ratio, designed for precise mounting on adapter sleeves or withdrawal sleeves. |
| C3 | Specifies a greater than normal radial internal clearance, suitable for applications with expected thermal expansion or where interference fits are used. |
1316 KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row ball bearing construction provides superior radial stiffness, enabling it to handle the specified high dynamic load rating of 19,890 lbf effectively. This makes it ideal for applications with significant radial loads.
- Precision Tapered Bore: The 1:12 tapered bore (K-designation) ensures a tight, secure fit on the shaft when used with appropriate sleeves, minimizing slippage and maintaining concentricity for precise operation.
- Optimized High-Speed Performance: The lightweight nylon cage reduces centrifugal forces, contributing to a high limiting speed of 5,300 rpm. The C3 clearance further supports high-speed operation by accommodating thermal expansion.
- Robust Material Construction: Manufactured from chrome steel for both rings and balls, the bearing ensures high durability, wear resistance, and a long operational lifespan under demanding conditions.
- Flexible Lubrication & Temperature Range: The open seal type allows for custom lubrication strategies. It operates effectively within a temperature range of -30°C to 110°C, offering versatility across various industrial environments.
1316 KC3 Bearing Typical Application Areas
The 1316 KC3 is ideally suited for machinery and systems requiring robust radial load support and high-speed capability. Key application sectors include:
- Industrial Gearboxes and Transmissions
- Material Handling Equipment (e.g., conveyor pulleys)
- Agricultural Machinery
- Industrial Fans and Blowers
- Pump and Compressor Systems
