4304 2RS double row Deep groove Ball bearing
Double row deep groove ball bearings of series 42 and 43 correspond in their structure and function to single row deep groove ball bearings arranged in pairs ,making them almost as versatile, practical.
Double row deep groove ball bearings correspond in design to single row deep groove ball bearings. Their deep, uninterrupted raceway grooves have a close osculation with the balls, enabling the bearings to accommodate radial loads and axial loads in both directions. Double row deep groove ball bearings are very suitable for bearing arrangements where the load carrying capacity of a single row bearing is inadequate.
The main dimensions of double row deep groove ball bearings correspond to DIN 625-3:2011.
The Benefits of Deep Groove Ball Bearings
1.Ability to Carry Radial and Axial Loads
2.Low Friction
Low friction also results in lowered noise and vibration, making these bearings ideal for high rotational environments, where they will use less lubrication than their traditional counterparts.
3.Easy to Install
Deep groove ball bearings are easy to install, which leads to simplified assembly and higher load capacity.
