1210KC3 5 Bearing Product Overview & Core Advantages
The 1210KC3 5 is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and rigidity. Featuring a tapered bore (1:12) for precise interference fits, this bearing is designed for high-precision and high-reliability scenarios. Its double row ball construction provides superior stability and load distribution, making it an ideal choice for supporting combined loads in demanding industrial environments. The C3 radial internal clearance and optimized nylon cage contribute to its reliable performance across a wide operating temperature range.

| Code Segment | Technical Meaning |
|---|---|
| 1210 | Standard bore diameter (50 mm) and series designation |
| K | Tapered bore with 1:12 ratio for secure shaft mounting |
| C3 | Greater than normal radial internal clearance for thermal expansion |
| 5 | Contact angle designation optimized for radial load capacity |
1210KC3 5 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact design provides exceptional stiffness and can accommodate significant radial loads (dynamic: 5962 lbf, static: 2059 lbf). The optimized contact angle ensures efficient load distribution across both ball rows.
Precision Tapered Bore: The 1:12 tapered bore enables precise interference fits on tapered shafts, ensuring secure mounting and eliminating internal clearance for maximum running accuracy.
Optimized Cage Design: The nylon cage provides excellent guidance for the balls, contributing to smooth operation and reduced friction at limiting speeds up to 10,000 rpm.
Wide Operating Range: Manufactured from chrome steel with C3 clearance, this bearing operates reliably across a temperature range of -30°C to 110°C, making it suitable for various industrial environments.
