Characteristic
Deep groove ball bearings can not be separated from the entity bearing inner and outer ring, cage and a steel ball, use is very extensive. The utility model has the advantages of simple design, reliability, durability and easy maintenance. The utility model is suitable for the requirements of high speed, low noise and low vibration. The radial and axial bearing capacity in the inner and outer rings of the deep groove ball raceway, the section radius slightly larger than the radius, the single row deep groove ball bearings at high speeds can bear radial load, also can withstand the axial load of two-way.
Angle misalignment compensation
The compensation ability of deep groove ball bearing misalignment is limited, so the bearings must be accurate positioning. If the rolling body is not in a state of rolling, the internal stress of the bearing is increased, so the bearing life is shortened. In order to limit the additional bearing stress in the lower range for deep groove ball bearing is only allowed to tilt a small angle (depending on load).
Due to its internal structure, double row deep groove ball bearing no compensation ability not. When using this type of bearing, the inclination angle is not allowed.
Load and allowable inclination angle
Deep groove ball bearing
Standard design variant
Design of KMR deep groove ball bearing is divided into open and sealed design.
Open bearings are suitable for high speed and ultra high speed operation.
Suffix 2Z indicates that the two side clearance seal is suitable for high speed operation.
Bearing the suffix 2RSR said bilateral lip seal, using nitrile resin rubber NBR ring, suitable for medium speed.
lubrication
Open bearing grease or oil lubrication. Deep groove ball bearings with bilateral gap sealing or lip seal of high quality oil, used for lifetime lubrication.
