Five kinds of bearing structure, performance characteristics

2020-09-16

Thrust taper roller bearing structure, performance characteristics? 

The rolling body of thrust tapered roller bearing is tapered roller, and in structure, the rolling bus and the racetrack bus of the washer all intersect at a certain point on the bearing axis, so the rolling surface can form pure rolling and the limit speed is higher than that of thrust cylindrical roller bearing.

Thrust taper roller bearing can withstand unidirectional axial load.

Thrust tapered roller bearings are of type 90000.

Due to the low production volume of thrust taper roller bearing, the models produced by various factories are mostly non-standard external dimensions, while the series of standard external dimensions and varieties produced are less, so there is no national standard for the external dimensions of this type of bearing.

Structure and performance characteristics of thrust angular contact ball bearing? 

Thrust angular contact ball bearing contact Angle 60 ° commonly used thrust angular contact ball bearings are generally two-way thrust angular contact ball bearings, mainly used for precision machine tool spindle, commonly used together with the double row cylindrical roller bearing, it can be subject to bi-directional load and have high precision, good rigidity, low temperature, high speed, the advantages of convenient operation {TodayHot}. 

The structure and performance characteristics of double row tapered roller bearing

Double-row tapered roller bearings have a variety of structures, the largest of which is type 35,000, with a double raceway outer ring and two inner rings, and a spacer between the two inner rings. The clearance can be adjusted by changing the thickness of the spacer.This type of bearing can bear both radial load and bidirectional axial load, and can limit axial displacement of the shaft and housing within the axial clearance range of the bearing. 

Structural features of tapered roller bearings. 

Tapered roller bearings are of type code 30000, tapered roller bearings are separable bearings.In general, and especially in the dimensions specified in GB/T307.1-94 "Rolling Bearing Center Bearing tolerance", between the outer ring and the inner assembly of tapered roller bearings is 100% interchangeable.The Angle of the outer ring and the diameter of the outer raceway have been standardized to the same size as the outer raceway.Changes during design and manufacture are not allowed.As a result, the outer ring and inner assembly of tapered roller bearings can be interchangeable in the world.

Tapered roller bearings are mainly used for bearing radial and axial combined loads.Compared with angular contact ball bearing, the bearing capacity is large and the limit speed is low.Tapered roller bearings are capable of bearing axial loads in one direction and can limit axial displacement in one direction of the shaft or housing.

Deep groove ball bearing characteristics? 

Structurally, each ring of a deep groove ball bearing has a continuous groove {HotTag} raceway whose cross section is approximately one third of the equatorial circumference of the ball.

Deep groove ball bearing is mainly used to bear radial load, but also can bear some axial load.

When the radial clearance of the bearing increases, it has the property of angular contact ball bearing and can bear the alternating axial load in two directions.

Compared with other bearings of the same size, this kind of bearing has low friction coefficient, high limit speed and high precision, making it the preferred bearing type for users.

Deep groove ball bearing is simple in structure, easy to use, is the largest batch of production, the most widely used range of bearings.
