Bearing several simple classification

Bearing several simple classification
1. Rolling classified by type of structure (1) can bear the load bearing its nominal direction or different contact angles, divided into:
1) radial bearings ---- mainly used to bear radial load high precision bearing, its nominal contact angle from 0 to 45. Press the nominal contact angle is different, is divided into: radial contact bearings ---- nominal contact angle is zero radial bearings: Radial angular contact bearings ---- nominal contact angle greater than the centripetal 0-45 bearings.
2) thrust bearings ---- mainly used for axial load bearing, its nominal contact angle greater than 45-90. Press the nominal contact angle is divided into different: axial contact bearings ---- nominal contact angle of 90 thrust bearings: Axial angular contact bearings ---- nominal contact angle greater than 45 but less than 90 of the thrust bearing.
(2) the type of rolling element bearing according divided into:
1) ball bearing rolling elements ---- Ball:
2) roller bearings ---- rolling body for roller. Roller Bearing press roller types, divided into: cylindrical roller bearings ---- rolling body is cylindrical roller bearings, cylindrical roller ratio of length to diameter is less than or equal to
3; needle roller bearings ---- rolling elements are Rolling mill bearing, needle length to diameter ratio greater than 3 but less than or equal to the diameter of 5mm; tapered roller bearings ---- rolling body is tapered roller bearings; aligning roller bearings eleven rolling body is spherical roller bearings.
(3) whether the bearing aligning their work, divided into:
1) aligning bearings ---- raceway is spherical shape, able to adapt to the two raceways angular deviation between the axis and bearing angular motion;
2) non-aligning bearings (rigid bearing) ---- can impedance path between roller bearing axis offset angle.
