1312KC3 Bearing Product Overview & Core Advantages
The 1312KC3 is a double row angular contact ball bearing designed for exceptional performance in demanding applications. This precision bearing features a tapered bore (1:12) for secure shaft mounting and is pre-lubricated for immediate operation. Its core strength lies in its ability to support high radial loads while offering a significant degree of rigidity. Manufactured with chrome steel rings and balls, and a lightweight nylon cage, it is engineered for reliable, long-lasting service in high-speed and high-precision environments.
1312KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1312 | Standard bore diameter (60 mm) and outside diameter (130 mm) designation. |
| K | Indicates a tapered bore with a 1:12 ratio, enabling precise interference fits on adapter sleeves or withdrawal sleeves. |
| C3 | Specifies a greater radial internal clearance than the Normal (C0) group. This is optimal for applications with expected thermal expansion or where a tighter fit is used. |
1312KC3 Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior rigidity and enables the bearing to accommodate high radial loads, making it suitable for applications with significant shaft deflection or heavy loads.
- Optimized for High-Speed Operation: The lightweight nylon cage reduces centrifugal forces, contributing to a high limiting speed of 6,300 rpm. This makes it an excellent choice for high-speed applications.
- Precision Tapered Bore: The K-designation tapered bore allows for precise axial adjustment and a secure, slip-free fit on the shaft, which is critical for maintaining accuracy in precision machinery.
- Ready-to-Use & Durable: The bearing comes pre-lubricated and features an open design, facilitating re-lubrication for extended service life. The use of high-grade chrome steel ensures durability and resistance to wear.
1312KC3 Bearing Typical Application Areas
This bearing is ideally suited for a range of industrial machinery requiring robust performance and precision, including:
- Electric Motors and Gearboxes
- Industrial Pumps and Compressors
- Material Handling Equipment
- Agricultural Machinery
- Various types of Transmission Systems
