Introduce the selection and requirements of sealing materials.The sealing material shall meet the requirements of sealing function. Due to different sealed media and different working conditions of equipment, sealing materials are required to have differe
The bearing sealing ring is an annular cover composed of one or several parts, which is fixed on one ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent leakage of lubricating oil and invasion
Accuracy class of tapered roller bearings.The accuracy of bearing mainly includes two aspects, one is dimensional accuracy, the other is rotation accuracy. The former is required after the bearing is installed. The rotation accuracy is to specify the rang
4 ways to improve bearing rigidity.1. Bearing configuration. Bearing configuration also has a great impact on bearing rigidity. Generally speaking, for centripetal thrust ball bearings and roller bearings, when used in pairs, it is appropriate to adopt th
Four key points of correct force application when assembling and disassembling bearings.(1) The resultant force of the force shall pass through the axis of the bearing as far as possible, which requires that the force application point shall be uniform, s
Installation scheme of self-aligning roller bearing1. The self-aligning roller bearing is equipped with a drum roller bearing between the inner ring with two raceways and the outer ring with spherical raceway. The curvature center of the outer ring racewa
The reasons affecting the roundness of the inner race of rolling bearing.1. The roundness of the inner race of rolling bearing is an important quality index, which directly affects the working accuracy, stability and service life of the bearing. Grinding
After the bearing is installed, it shall be checked to ensure that the bearing is installed in place, rotates flexibly and has no clamping stagnation. If the bearing is installed improperly, the bearing temperature will rise rapidly and be damaged, and ev
Bearing is essential for mechanical operation, but bearing also has its own shortcomings that can not be overcome. Bearing is one of the sound sources of mechanical noise. So how do we minimize the noise of tapered roller bearings?Discussing the mechanism
In the assembly process of thrust ball bearing, plane thrust bearing is mainly used to bear axial load. Although the installation operation of thrust bearing is simple, the installation operation of thrust ball bearing is relatively simple, but errors sti
