1222-K C/3 Bearing Product Overview & Core Advantages
The 1222-K C/3 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 under demanding conditions. Its double row design provides superior load-carrying capacity, making it ideal for machinery where space constraints and performance reliability are critical. Manufactured from high-grade chrome steel and featuring a stainless steel cage, it ensures long service life and consistent performance in industrial environments.
1222-K C/3 Bearing Model Code Explained, Specifications & Naming Convention
| Suffix Code | Technical Meaning | Performance Benefit |
|---|---|---|
| K | 1:12 Tapered Bore | Enables precise interference fit on tapered shafts for secure mounting and reduced slippage |
| C/3 | CN Radial Internal Clearance Group | Provides optimal internal clearance for general industrial applications with moderate operating temperatures |
1222-K C/3 Bearing Structural Features & Performance Benefits
High Rigidity & Load Capacity: The double row angular contact construction enables the bearing to withstand substantial radial loads (19,890 lbf dynamic rating) while maintaining dimensional stability. The optimized raceway geometry distributes loads evenly across both ball rows.
Precision Tapered Bore Design: The 1:12 tapered bore ensures a tight interference fit when mounted with adapter sleeves, eliminating clearance and minimizing vibration. This feature is particularly valuable in applications requiring precise shaft positioning and high rotational accuracy.
Enhanced Durability: Constructed from chrome steel for both rings and balls, combined with a stainless steel cage, the bearing offers excellent resistance to wear and corrosion. The CN clearance group provides balanced internal clearance for reliable operation across the specified temperature range (-30° to 110°C).
Optimized Performance: With a limiting speed of 4,300 rpm and factory-applied lubrication, the bearing delivers smooth operation and reduced maintenance requirements in continuous duty applications.
