3203-ATN9C3 SKF Double Row Angular Contact Ball Bearing Polyamide Cage 17mm x 40mm x 17.5mm
The 3203-ATN9C3 SKF Double Row Angular Contact Ball Bearing is a premium precision bearing engineered for high-performance applications requiring simultaneous radial and axial load handling. This versatile bearing combines compact design with exceptional durability, making it ideal for demanding industrial environments.
Design & Functionality
Angular contact ball bearings feature raceways in the inner and outer rings that are strategically displaced along the bearing axis. This unique design enables them to accommodate combined loads—both radial and axial forces acting simultaneously. The double row configuration provides:
- Accommodation of axial loads in both directions
- Exceptionally stiff bearing arrangements
- Ability to withstand tilting moments
- Reduced axial space compared to two separate single row bearings
Key Specifications
- Bore Diameter: 17mm
- Outer Diameter: 40mm
- Width: 17.5mm
- Configuration: Double Row
- Cage Material: Polyamide
- Internal Clearance: C3 (allows expansion at high speeds and elevated temperatures)
- Manufacturer: SKF
Ideal Applications
This bearing is particularly suited for high-speed, precision applications including:
- Gearboxes and transmission systems
- Electric motor spindles
- Heavy-duty machinery requiring combined load support
- Industrial equipment operating at elevated temperatures
The polyamide cage construction ensures reliable performance with minimal maintenance, while the C3 internal clearance specification guarantees optimal operation across varying temperature ranges and rotational speeds.
