1208KC3 Bearing Product Overview & Core Advantages
The 1208KC3 is a metric double row angular contact ball bearing engineered for applications requiring high radial load capacity and precise operation. Featuring a 1:12 tapered bore for secure shaft mounting, this bearing delivers exceptional rigidity and stability. Its C3 radial internal clearance makes it suitable for applications with thermal expansion or where interference fits are used. Manufactured with chrome steel rings and balls, and a nylon cage, it offers reliable performance in demanding industrial environments.
1208KC3 Bearing Model Code Explained, Specifications & Naming Convention
| Code Segment | Technical Meaning |
|---|---|
| 1208 | Standard bore diameter (40 mm) and series designation |
| K | Tapered bore with 1:12 ratio for precise shaft fitting |
| C3 | Greater radial internal clearance than normal group |
1208KC3 Bearing Structural Features & Performance Benefits
Double Row Design: Provides enhanced rigidity and load distribution compared to single row bearings, making it ideal for applications with significant radial loads.
High Load Capacity: With a dynamic radial load rating of 4478 lbf and static radial load rating of 1564 lbf, this bearing handles substantial combined loads effectively.
Tapered Bore Advantage: The 1:12 taper ensures secure mounting on adapter sleeves or tapered shafts, preventing creep and maintaining precise alignment.
Optimized Cage Design: The nylon cage contributes to smooth operation at limiting speeds up to 11,000 rpm, reducing friction and heat generation.
Pre-lubricated Construction: Factory lubrication ensures immediate operation and reduces maintenance requirements within the specified temperature range of -30°C to 110°C.
1208KC3 Bearing Typical Application Areas
- Electric Motors and generators requiring precise shaft positioning
- Industrial Gearboxes and transmission systems
- Material Handling Equipment such as conveyor systems
- Agricultural Machinery with high radial load demands
- Pump Systems requiring stable bearing performance
- Machine Tool Accessories where tapered bore mounting is preferred
