Deep groove ball bearings are the most commonly used rolling bearings. It has a simple layout; it is easy to use. It is mainly used to accept radial loads; but when the bearing radial clearance is increased; it has the function of a certain angle touch ball bearing; it can accept the diameter and the shaft. To the combined load. When the speed is high and the thrust ball bearing is not suitable; it can also be used to accept the pure axial load. It is comparable to other types of bearings with the same scale; the friction coefficient of such bearings is antagonistic. But the impact is not suitable for accepting. Heavy load.
Deep groove ball bearings are mounted on the shaft; within the axial clearance of the bearing; axial displacement in either direction of the shaft or casing; thus axial positioning in both directions. In addition; The ability to adjust the heart; when it is 2'~10' with respect to the hole of the casing; it can still work normally; but it has a certain influence on the bearing life.
Deep groove ball bearing cages are mostly steel plated wave cages; large bearings are mostly made of metal body cages.
Deep groove ball bearings are widely used in automobiles, tractors, machine tools, motors, water pumps, agricultural machinery, textile machinery, etc.
The deep groove ball bearing device with dust cover and sealing ring has been filled with excessive smooth grease; it should not be heated or removed before the device; it does not need to be smooth during use; the operating temperature is -30 °C to +120 °C. The self-aligning ball bearing outer ring raceway is spherical; it has a self-aligning function; therefore, it can actively adjust the axial misalignment caused by the deflection or different center of the shaft or the outer casing.
Product characteristics:
Firstly accept radial load; together accept small axial load. The axial displacement of the shaft (housing) is constrained within the clearance limit; it has the function of active centering; it can work normally under the condition that the inner and outer sides are relatively small; Suitable for parts where the bearing seat hole cannot be strictly ensured for coaxiality.
Product features: Self-aligning ball bearings have two kinds of layout: cylindrical hole and tapered hole; the material of the cage is steel plate, synthetic resin, etc. It is characterized by the outer ring raceway being spherical shape; it has active self-aligning; it can compensate different hearts and The error caused by the deflection of the shaft; but the relative inclination of the inner and outer rings must not exceed 3 degrees.
