1210KTN Bearing Product Overview & Core Advantages
The 1210KTN is a double row angular contact ball bearing designed for applications requiring high rigidity and precise operation. This metric bearing features a tapered bore (1:12) and open construction, enabling it to handle significant combined loads—both radial and axial forces. Its double row design provides enhanced stability and load-carrying capacity compared to single row alternatives, making it ideal for machinery where space constraints and performance reliability are critical. The bearing comes pre-lubricated and features a nylon cage for smooth operation at high speeds.
Model Code Breakdown
| Code Segment | Technical Meaning |
|---|---|
| 1210 | Basic bearing designation: 50 mm bore, 90 mm OD, 20 mm width |
| K | Tapered bore with 1:12 ratio |
| TN | Nylon cage (injection molded) for reduced weight and smooth operation |
1210KTN Bearing Structural Features & Performance Benefits
- High Rigidity & Load Capacity: The double row design provides superior stiffness and can handle combined radial and axial loads simultaneously. With a dynamic load rating of 5962 lbf and static load rating of 2059 lbf, it ensures reliable performance under demanding conditions.
- Precision & Stability: Manufactured from chrome steel with tight dimensional tolerances (bore: -0.012mm to 0; OD: -0.015mm to 0), ensuring consistent performance and long service life.
- High-Speed Capability: The lightweight nylon cage (TN) reduces centrifugal forces, enabling operation at limiting speeds up to 10,000 rpm. The optimized internal geometry further enhances high-speed performance.
- Easy Mounting & Maintenance: The tapered bore (K) facilitates precise interference fit on tapered shafts or adapter sleeves. Pre-lubrication and standard radial clearance (CN) ensure ready-to-install convenience.
1210KTN Bearing Typical Application Areas
- Machine Tool Spindles: High-precision machining centers requiring rigidity and speed
- Industrial Gearboxes: Power transmission systems with combined loading
- Material Handling Equipment: Conveyor systems and automated guided vehicles
- Agricultural Machinery: PTO shafts and implement drives
- Electric Motors & Generators: Medium to high-speed rotating assemblies
