Spherical roller bearings are precise mechanical parts, whose accuracy is calculated in microns. In the long-term storage and use process, due to changes in the internal structure or stress changes will cause changes in bearing size, resulting in loss of bearing accuracy. Therefore, in order to ensure the dimensional accuracy of …

Bearing selection is an important, meticulous and complex technical work, which includes bearing structure selection, performance selection and service life calculation. Although there is no hard sequence and rules in the selection of bearings, the usual selection steps are consistent.To select a suitable bearing from a large num…

At present, the life model based on statistics still plays a leading role in bearing life prediction, but it is found in test and engineering application that the life calculated by the statistical life model is usually conservative an…
[See details]Tapered roller bearings are usually of separate type, that is, a tapered inner ring assembly consisting of an inner ring with a roller and a cage assembly can be mounted separately from the cone outer ring (outer ring).Tapered roll…[See details]
Tapered roller bearings mainly bear radial and axial combined loads. Bearing capacity depends on the Angle of the raceway of the outer ring, and the greater the Angle, the greater the bearing capacity. This kind of bearing belongs …[See details]
The rotation accuracy of tapered roller bearings refers to:1, complete set of bearing inner ring and outer ring radial runout;2, complete set of bearing inner ring and outer ring end face raceway beating;[See details]
The reasons for bearing noise are more complex. One is the wear of the inner and outer rings of bearings. Because of this wear, the bearing and the housing, bearing and shaft are destroyed, resulting in the axis deviated from the c…[See details]
Determination of clearance of bearing monomerWhen determining the clearance of bearing monomer, stand the bearing on the platform, press the bearing outer ring with your hand, pay attention to keeping the inner ring from tilting, t…[See details]
Bearing disassembly should be carried out as carefully as installation. Attention should be paid to not damage bearings and parts, especially the disassembly of interference fit bearings, which is difficult to operate. Therefore, i…[See details]
