What is the difference between deep groove ball bearings and cylindrical roller bearings? How to choose between the two?

 Deep groove ball bearing (single row radial ball bearing) is the most widely used rolling bearing. It is characterized by low frictional resistance and high speed. It can be used on parts that bear radial load or a combined load that acts on both radial and axial directions. It can also be used on parts that bear axial load, such as low-power motors, Automobile and tractor gearboxes, machine tool gearboxes, general machines, tools, etc.

Cylindrical roller bearings. The internal structure of the cylindrical roller bearing adopts the parallel arrangement of the rollers, and the spacers or spacers are installed between the rollers, which can prevent the inclination of the rollers or the friction between the rollers, and effectively prevent the increase of the rotation torque.

Both bearing and cylindrical roller bearings mainly bear radial load and can bear a small part of axial load.

The bearing has a higher operating limit speed, a relatively large axial load bearing capacity, and a relatively small radial load bearing capacity. 2. The use limit speed of cylindrical roller bearings is not as high as that of deep groove ball bearings. The analysis of metal stamping processing can basically not bear the axial load, but the radial load bearing capacity is relatively large.

3. How to choose between the two? Cylindrical roller bearings are preferred under low-speed and heavy-load conditions, and deep groove ball bearings are preferred under high-speed and light-load conditions.
