5304 2RSC3 Double Row Radial Ball Bearings have angular contact ball bearing which is designed to meet the demand for increased axial and radial rigidity in the applications where space is limited. 
This specific ball bearing are used for different necessities which are for heavy radial loads, two directional loads are encountered, and combined thrust loads and radial.
Another important fact is the non-filling slot allows higher speed operations. This specific bearing in the 5300 Series are produced with shields and seals. The angle of contact converts outside of the bearing which offers increased resistance.

5304-2RSC3 This single-row radial bearing has C3 radial internal clearance for radial slack between the inner and outer rings that is greater than CN (normal) to compensate for thermal expansion 5304DDUC3 it has two press metal seals on outer ring to protect bearing from any alien objects and corrosion of internal components and they are non-contacts toward inner ring, it also has metal retainer, the retainer also referred to as the cage or separator, is used to separate and position the balls at equal intervals around the bearing raceways. The 5304-2RSC3 is precision ABEC1 or P0 international standard accuracy, 5304.2RSR.C3 is capable of carrying axial load and rotation at the same time as light duty ball bearing.

Rolling bearings use rolling elements to maintain the separation between moving parts to reduce rotational friction and support radial and axial loads. These elements can be one of the following types: ball, cylindrical, spherical, barrel, needle, spindle, or tapered. All rolling bearings are open, shielded, or sealed. Sealed and Shielded bearings are lubricated with oil or grease in the bearing factory, while open bearings are meant to be lubricated in place, with periodic reapplication of lubrication, based on use. The shield protects the working parts of the bearing from environmental debris that may be introduced and could reduce the ball bearing speed and lifespan. Rolling bearings are used in a range of applications from agricultural machinery to conveying equipment, electric motors, CNC machinery, trucks, mining equipment, train, robotics, dental equipment, elevators, rolling mills, ship rudder shafts, and aggregate crushers, among others.
