1320L1KC3 Bearing Product Overview & Core Advantages
The 1320L1KC3 is a double row angular contact ball bearing designed for applications requiring high rigidity and precision. This metric system bearing features a tapered bore (1:12) for secure shaft mounting and is optimized to handle significant radial loads. Its double row construction provides superior stability and load-carrying capacity compared to single row designs, making it ideal for demanding industrial environments where reliability and performance are critical. The bearing comes pre-lubricated and features a C3 radial internal clearance, suitable for applications with thermal expansion or misalignment.
1320L1KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1320 | Standard bearing series designation |
| L1 | Tapered bore with 1:12 ratio |
| K | Tapered bore designation |
| C3 | Greater than normal radial internal clearance for thermal expansion |
1320L1KC3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row ball bearing construction provides enhanced stiffness and can support substantial radial loads (dynamic: 32,175 lbf, static: 12,825 lbf). The optimized contact angle distribution ensures stable operation under varying load conditions.
Precision Engineering: Manufactured from chrome steel for both rings and balls, with a brass cage for superior guidance and durability. The tight dimensional tolerances on bore diameter (100 mm, tolerance: -0.02mm to 0) and outside diameter (215 mm, tolerance: -0.03mm to 0) ensure precise fit and reliable performance.
Thermal Compensation: The C3 clearance accommodates thermal expansion in applications where operating temperatures may vary, preventing premature failure due to excessive preload.
Optimized Design: With a limiting speed of 4,000 rpm and protrusion of balls from bearing side faces (2.469 mm), the bearing is engineered for efficient operation in various industrial settings.
