4214 ATN9 - Double row deep groove ball bearings

Double row deep groove ball bearings correspond, in their design and
operation, to a pair of single row deep groove ball bearings. They are
robust in operation, requiring little maintenance, can operate at high
speeds and accommodate radial and axial loads in both directions. They
are slightly wider than single row bearings of the same bore and outside
diameter but have a considerably higher load carrying capacity.
• Versatile and robust design
• High-speed capability
• Accommodate high axial and radial loads in both directions
• Require little maintenance
