What are the differences and similarities between cylindrical roller bearings and deep groove ball bearings? What is the basis of the choice?
Deep groove ball bearings and cylindrical roller bearings the same point: mainly bearing radial load mainly, can bear a small part of axial load.Different points: deep groove ball bearings use high limit speed, axial load bearing capacity is relatively large, the radial load bearing capacity is relatively small; and the use of cylindrical roller bearing limit rotational speed without deep groove ball bearing is high, basically can not bear the axial load, but the radial load bearing capacity is relatively large.Selection basis: low speed heavy load, preferably cylindrical roller bearings, high speed light load, deep groove ball bearings. The specific bearing speed limit and rated load shall be checked by the mechanical design manual or consult with the manufacturers.
[cylindrical roller bearings]The moving body is a radial roller bearing of cylindrical roller. The internal structure of cylindrical roller bearing of the roller was 90 degrees vertical arrangement (which is also the cross roller bearing the name of the origin), interval retainer or isolation block is arranged between the roller and the roller can prevent between tilt or roller friction each other, effectively prevent the increase of rotational torque.[deep groove ball bearing]Deep groove ball bearings are the most common types of rolling bearings. A basic deep groove ball bearing consists of an outer ring, an inner race, a set of steel balls, and a set of retaining structures. Deep groove ball bearings are of two types, single row and double row. The deep groove ball structure is divided into two kinds of sealing and open structure. The open type means that the bearings are not sealed. The sealed deep groove ball is divided into dustproof sealing and oil tight sealing.
Cylindrical roller bearings are similar to deep groove ball bearings:The main load is radial load, can bear a small part of axial load.Cylindrical roller bearings differ from deep groove ball bearings:1, deep groove ball bearings use higher limit speed, axial load capacity is relatively large, radial load bearing capacity is relatively small;2, cylindrical roller bearings use the limit speed, no deep groove ball bearings, high, basically can not withstand axial load, but the radial load bearing capacity is relatively large.Selection of cylindrical roller bearings and deep groove ball bearings:In the case of low speed and heavy load, the cylindrical roller bearings should be preferred, and the deep groove ball bearings should be selected under the condition of high speed and light load. The specific bearing speed limit and rated load shall be checked by the mechanical design manual or consult with the manufacturer.
