The difference between ball bearing and roller bearing

1. The deep groove ball bearing USES the high limit speed, the axial load bearing capacity is relatively large, the radial load bearing capacity is relatively small;

2. The roller bearing USES the limit speed without deep groove ball bearing height, and can not bear axial load, but the radial load bearing capacity is relatively large.

Basis for selection of cylindrical roller bearing and deep groove ball bearing:

Under the condition of low speed and heavy load, the cylindrical roller bearing is preferred, and deep groove ball bearing is preferred under high speed light load. Refer to the mechanical design manual or consult the manufacturer for the ultimate speed and rated load of specific bearing.

[cylindrical roller bearings]

The moving body is the centripetal rolling bearing of the cylindrical roller. The internal structure of cylindrical roller bearing by roller are arranged 90 ° vertically cross each other (this is also in cross roller bearing the name of the origin), with intervals between roller holder or the isolation piece, can prevent mutual friction between roller tilt or roller, effectively prevent the rotation torque increases.

[deep groove ball bearing]

Deep groove ball bearing is the most common type of rolling bearing. The basic type deep groove ball bearing consists of an outer ring, an inner ring, a set of steel balls and a set of maintenance frames. Deep groove ball bearing type has a single row and double row two kinds, deep groove ball structure is sealed and open two kinds of structure, open without sealing structure refers to the bearing, seal type deep groove ball into dust seal and oil seal.
