2204KJ Bearing Product Overview & Core Advantages
The 2204KJ metric double row angular contact ball bearing represents a high-performance solution for applications requiring combined radial and axial load capacity. Featuring a tapered bore (1:12) and sealed construction, this precision bearing delivers exceptional rigidity and rotational accuracy. Its compact design, with a 20mm bore and 47mm outside diameter, makes it ideal for space-constrained, high-reliability applications where consistent performance under demanding conditions is essential.

| K | Tapered bore with 1:12 ratio |
| J | Steel cage with optimized design |
2204KJ Bearing Structural Features & Performance Benefits
Enhanced Rigidity: The double row angular contact design provides superior stiffness compared to single row bearings, making it ideal for applications requiring minimal deflection under combined loading conditions.
Superior Load Capacity: Engineered to handle significant radial loads while simultaneously accommodating axial loads in both directions, thanks to the optimized contact angle and double row configuration.
Sealed & Lubricated Design: The integrated sealing system protects against contamination while the factory-applied lubrication ensures consistent performance throughout the bearing's service life, supporting operation at limiting speeds up to 10,000 rpm.
Precision Engineering: Manufactured from chrome steel with tight dimensional tolerances and CN radial internal clearance, ensuring smooth operation and extended service life in precision applications.
