1210-K C/3 Bearing Product Overview & Core Advantages
The 1210-K C/3 is a metric double row angular contact ball bearing engineered for applications requiring high precision and reliable performance. Featuring a tapered bore (1:12 ratio), this bearing excels at handling combined radial and axial loads simultaneously while maintaining exceptional rigidity. Its optimized internal geometry and CN radial internal clearance ensure smooth operation and precise positioning in demanding industrial environments. The nylon cage construction contributes to reduced friction and quiet operation, making it ideal for high-speed applications.

| Code Segment | Technical Meaning |
|---|---|
| 1210 | Standard bore diameter 50 mm, outside diameter 90 mm |
| K | Tapered bore with 1:12 ratio |
| C/3 | Radial internal clearance group C3 (greater than normal clearance) |
1210-K C/3 Bearing Structural Features & Performance Benefits
Double Row Design for Enhanced Rigidity: The double row angular contact configuration provides superior stiffness and stability compared to single row bearings, effectively resisting moment loads and maintaining shaft alignment under demanding conditions.
Optimized Load Capacity: Engineered to handle combined radial and axial loads in both directions, this bearing offers a radial dynamic load rating of 5962 lbf and radial static load rating of 2059 lbf, ensuring reliable performance in heavy-duty applications.
High-Speed Capability: The nylon cage reduces rotational mass and friction, enabling limiting speeds up to 10,000 rpm while maintaining smooth operation and minimal vibration.
Precision Tapered Bore: The 1:12 tapered bore facilitates precise mounting on adapter sleeves, ensuring secure fitment and eliminating internal clearance for optimal performance.
Pre-Lubricated Design: Factory-applied lubrication provides immediate operational readiness and extends service intervals in standard operating conditions.
