3204 A-2Z SKF Double Row Angular Contact Ball Bearing 20mm x 47mm x 20.6mm
3204 A-2Z SKF Double Row Angular Contact Ball Bearing
This premium double row angular contact ball bearing from SKF is engineered for high-performance applications requiring simultaneous radial and axial load capacity. With a 20mm bore, 47mm outer diameter, and 20.6mm width, the 3204 A-2Z delivers exceptional precision and reliability in demanding industrial environments. The double row configuration provides enhanced load carrying capability, making it an ideal choice for precision machinery and heavy-duty equipment.
Key Features:
- Double row design for superior load carrying capacity in both radial and axial directions
- 30° contact angle optimised for efficient combined radial and axial load distribution
- Cover design on both sides (2Z) provides protection against contamination while allowing for lubrication
- Sheet steel cage construction for reliable operation and consistent performance
- Normal radial clearance for standard mounting applications
- Standard bearing steel construction ensures durability and extended service life
- Tolerance class P6/ABEC 3 for precision performance
- Extended operating temperature range: -20°C to +120°C
- Compact and rigid construction ideal for space-constrained applications
Design & Performance:
Angular contact ball bearings feature raceways in both inner and outer rings that are angularly displaced along the bearing axis. This innovative design enables the bearing to handle combined loads—radial and axial forces acting simultaneously—making it ideal for precision, high-speed applications. The double row configuration provides increased load capacity and improved stability compared to single row designs. The protective 2Z covers help shield the bearing from contaminants while maintaining accessibility for maintenance and lubrication.
