Summary: Understanding the characteristics of bearings is the key to use of bearings effectivily

Structure and performance characteristics ofBecause the rolling body in the thrust taper roller bearing is a cone roller,  the rolling bus and the raceway bus of the washer meet at a certain point on the axis line of the bearing, so the rolling surface can form pure rolling, and the ultimate speed is higher than that of the thrust cylinder roller bearing.

The thrust cone roller bearing can withstand unidirectional axial load.

The type of thrust cone roller bearing is called 90000 type.

Due to the low production volume of thrust cone roller bearings, most of the models tha thave been produced in various factories are non-standard external dimensions,while the series of standard external dimensions and varieties are less produced, so there is no national standard on external dimensions of such bearings at present

Structural and performance characteristics of double row taper roller bearings

Double row cone roller bearing structure is various, the largest number is 35000 type, there is a double raceway outer ring and two inner rings, there is a separate ring between the two inner rings, changing the thickness of the packer ring can adjust the clearance. This kind of bearing can bear bidirectional axial load while bearing radial load and limit axial displacement of shaft and shell within the range of axial clearance of bearing.

Structural and performance characteristics of taper roller bearings

The type code of taper roller bearing is 30000, and taper roller bearing is separated type bearing. Ingeneral, especially in GB/ t307. 1-94 "rolling bearing centripetal bearing tolerance", the outer ring and inner assembly of taper roller bearing within the range of dimensions involved are 100 percent interchangeable. The Angle of the outer ring and the diameter of the outer raceway have been standardized to be the same as the external dimension. Changes are not allowed at design time. So that the outer ring and inner assembly of taper roller bearings can be universally interchanged worldwide.

Conical roller bearings are mainly usedto bear combined radial and axial loads, mainly radial loads. Compared withangular contact ball bearing, the bearing capacity is large and the ultimatespeed is low. Tapered roller bearings are capable of bearing axial loads in onedirection and limiting axial displacement in one direction of the shaft orhousing.

Structural and performance characteristics of deep groove ball bearings

Each sleeve of deep groove ball bearing has a continuous groove raceway with a cross section of approximately one third of the length of the equatorial circumference of the ball.

Deep groove ball bearing is mainlyused to bear radial load, but also can bear certain axial load.

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

Compared with other types of bearingof the same size, this kind of bearing has small friction coefficient, highlimit speed and high precision. It is the preferred type of bearing whenselecting the type by users.

Deep groove ball bearing structureis simple, easy to use, is the largest production volume, the most extensiveapplication of bearings.
