1, thrust force circular cone roller bearings structure, performance characteristic
Because in the thrust force circular cone roller bearings rolling body is the circular cone roller, in structure because the trundle generatrix and the gasket roller conveyer generatrix remits in the bearing axis core some, thus the trundle surface may form the pure trundle, the limit rotational speed is higher than the thrust force cylindrical roller bearing.
The thrust force circular cone roller bearings may withstand the unidirectional axial load.
The thrust force circular cone roller bearings type code number is 90000.
Because the thrust force circular cone roller bearings productivity are few, various factories have produced model many for non-standard external dimensions, but the standard external dimensions series, the variety production are few, thus still did not have this kind of bearing at present external dimensions national standards appearing.

2, the thrust force corner joint touches the ball bearing the structure, the performance characteristic
The thrust force corner joint touches the ball bearing angle of contact generally to touch the ball bearing for 60° the commonly used thrust force corner joint generally to touch the ball bearing for the bidirectional thrust force corner joint, mainly uses in the precision machine tool main axle, together coordinates with the double row cylindrical roller bearing to use generally, may withstand the bidirectional axial load, has the precision to be high, the rigidity is good, the temperature rise is low, the rotational speed is high, merits and so on assembling and dismantling convenience.

3, double row circular cone roller bearings structure, performance characteristic
The double row circular cone roller bearings structure is many, most massive is 35000, some double roller conveyer addendum circle and two inner loops, between two inner loops have a spacer ring, changes the spacer ring thickness to be possible to adjust the windage.This kind of bearing may withstand the bidirectional axial load during withstanding radial direction load, may limit the axis and the outer covering axial displacement in the bearing axial windage scope.

4, circular cone roller bearings unique feature
The circular cone roller bearings type code number is 30000, circular cone roller bearings for separation bearing.In the ordinary circumstances, in the size scope circular cone roller bearings addendum circle which "Rolling bearing Centripetal Bearing Common difference" involves in GB/T307.1-94 is in particular 100% may exchange the use general with in module between.The addendum circle angle as well as outside the roller conveyer diameter size has been stipulated same with the external dimensions by the standardization.Does not permit when the design manufacture changes.So that causes the circular cone roller bearings the addendum circle and in between the module may in the worldwide scale the general exchange.
The circular cone roller bearings mainly use in withstanding by the radial direction load primarily radial direction and the axial union load.Compares, the bearing capacity with the angle contact ball bearing is big, the limit rotational speed is low.The circular cone roller bearings can withstand a direction the axial load, can limit the axis or an outer covering direction axial displacement.
5, gulley ball bearing characteristic
On the structure of the deep groove ball bearings each collar has a cross-sectional area is approximately the circumference of the equator in 3 consecutive openers in the road. deep groove ball bearings mainly take radial load is used, and can withstand a certain amount of axial loads. When the bearing radial clearance increases, with angular contact ball bearings, bearing two directions can be changed to the axial load. And the same size than other type bearings, bearing the low friction coefficient, and the limits high-speed, high precision, is that the user-preferred bearing type. deep groove ball bearing simple structure, easy to use, and is the largest production volume, the application of the most extensive such bearing.
