ship loader bearing ball bearing

2) roller bearings, roller roller. Roller bearing press roller variety, can be divided into: cylindrical roller bearing.

The rolling bearing cylindrical roller, cylindrical roller and the length of the straight

The ratio of diameter less than ship loader bearing‍ or equal to 3; needle roller bearings, needle roller bearing is a rolling body, the needle length to diameter ratio

In 3, but the diameter is less than or equal to 5mm; tapered roller bearing

- the rolling bearings worm gear speed reducer‍ tapered roller; roller bearings by the rolling bearing spherical roller.

(3) aligning whether according to their task, divided into:

1) aligning bearings, raceway is spherical shape, can adapt to Other bearing‍ the two bearing raceway deviation angle between the axis lines and angular motion;

2) non self-aligning bearing (rigid bearing) - bearing raceway between the axis line impedance angle offset.                                        ‍
