3204 A-2Z/C3MT33 SKF Double Row Angular Contact Ball Bearing 20mm x 47mm x 20.6mm
3204 A-2Z/C3MT33 SKF Double Row Angular Contact Ball Bearing
This high-precision double row angular contact ball bearing from SKF is engineered to handle simultaneous radial and axial loads with exceptional reliability. The 3204 A-2Z/C3MT33 combines compact design with robust performance, making it an ideal choice for precision machinery and equipment requiring superior load capacity in a compact footprint.
Design & Construction
Double row angular contact bearings feature two rows of angularly displaced ball races, providing superior load-carrying capacity compared to single row bearings. This configuration enables efficient handling of combined radial and axial loads simultaneously, delivering enhanced rigidity and stability. The dual-row design makes this bearing particularly suitable for applications where space is limited but load capacity demands are high.
Constructed from standard bearing steel with a sheet steel cage, this bearing offers reliable operation with excellent durability. The sealed design with covers on both sides provides protection from contamination while maintaining smooth, low-friction performance in clean to moderately dusty environments.
