A, four-point contact ball bearings

Four-point contact ball bearings are composed of two laps, compact structure, light weight, steel ball contact with circular arc at four o 'clock, can bear axial force at the same time, the radial force and overturning moment, has the strong ability of dynamic load.

The second and third row roller wheel bearing

Three rows of roller wheel bearing increase the bearing capacity of lead bearing height direction, all kinds of bearing respectively have different raceway and roller group, so under the same loading conditions, the diameter of the bearing can be significantly reduced, so that the host is more compact, wheel bearing is a kind of high bearing capacity.

Three bearing, crossed cylindrical roller rotary table

Single cross roller wheel bearing is composed of two seat compact structure, light weight, high precision manufacturing, assembly, small gap of installation accuracy requirement is high, the roller of 1:1 cross arranged, can bear axial force at the same time, the overturning moment and large radial force.

Four, double volleyball wheel bearing

Double wheel bearing with two rows of steel ball up and down, so it can bear radial force at the same time, the axial force and overturning moment.In order to adapt to the different proportion of each moment, contact Angle ranging from very small to 90 degrees, when the distribution of ball diameter phase at the same time, call every line of steel ball bearing capacity is proportional to the selected ball diameter, therefore, in the support section under the condition of the same height, bear axial force and overturning moment at the same time, double row bearing section size can be better used.

Five, ball rolling wheel bearing

Wheel bearing can withstand a larger part of the axial force and radial load and overturning moment of the joint function, wheel bearing has the characteristics of long life, the appearance of this kind of bearing usually has a larger size
