7220 B NSK Single Row Angular Contact Ball Bearing 100mm x 180mm x 34mm
7220 B NSK Single Row Angular Contact Ball Bearing
The 7220 B NSK Single Row Angular Contact Ball Bearing is a precision bearing engineered for high-speed applications requiring simultaneous radial and axial load capacity. This robust single row configuration delivers reliable performance in demanding industrial environments where combined loading conditions are present.
Design & Construction
Angular contact ball bearings feature offset raceways on both the inner and outer rings, enabling efficient handling of combined loads. The single row design is particularly suited for applications where axial loads act primarily in one direction, providing an ideal balance between load capacity and compact form factor.
