Bearing 6307 – 2ZR

Single row ball bearings are the most common type of bearing. Deep Groove Ball Bearing HRB Deep Groove Ball Bearing is an integral bearing. Its inner and outer grooves are deep groove type, can bear radial load, bidirectional axial load and combined load and suitable for high speed rotation. They are used very widely. The face grooves on both the inner and outer washers have a slightly larger radius arc than the ball. In addition to the diametric load, the bearing can withstand axial loads in both directions. Due to their low torque, they are well suited to applications requiring high speeds and low energy losses.
In addition to open-type ball bearings, these bearings typically have a steel or rubber guard on one or both sides and are lubricated with oil or grease. Similarly, locating bearings are sometimes used externally. Cage made of stamped steel is most commonly used.
The international designation of this type of bearing usually has 4 codes starting with the number 6.
