Miniature roller bearings are rolling bearing with short cylinder, cone or waist drum roller as the rolling body.There are mainly centripetal short cylindrical roller, double row centripetal spherical roller, conical roller and thrust roller and other structural types.
Miniature roller bearings classification:
Cylindrical roller bearing
This type of roller is mainly used for cylindrical roller bearings, but also can be directly used in the roller assembly machinery.This kind of roller has been standardized in size and can be used as a commodity roller for design and user selection.
Long cylindrical roller bearing
This kind of miniature roller bearings can be divided into axle diameter and non-axle diameter, mainly used for long cylindrical roller bearings, but also can be directly used in the roller assembly machinery.
Folding spherical roller bearing
The rolling surface of a roller is spherical.The miniature roller bearings with this roller has automatic centering performance and can bear a great load.Spherical roller is divided into asymmetric type and symmetric form, the general asymmetry of the large end surface for the spherical, symmetric shape of the two end surface for the plane.The performance of symmetric spherical roller is better than that of non-symmetric spherical roller.This kind of miniature roller bearings are used for aligning roller bearing and thrust aligning roller bearing.
Taper roller bearing
Assumes the circular truncated cone, the cone Angle is usually 1 ° ~ 4 ° 20 ', there are less than 1 ° or greater than 4 ° 20 ', more than 2 °.Roller length is generally not more than two times the diameter of the roller large end.This kind of miniature roller bearings are mostly used for tapered roller bearings, large taper Angle roller is basically used for thrust tapered roller bearings.
