Koyo imported bearings shall be cleaned with gasoline or kerosene before installation, and used after Relevant Steps drying, and good lubrication shall be ensured. Koyo imported bearings are generally lubricated with grease or oil.
When grease lubrication is used, grease with excellent properties such as no impurities, oxidation resistance, rust prevention and extreme pressure Relevant Steps shall be selected. Double row tapered roller bearing with sealing structure and water pump shaft connecting bearing have been filled with grease,
which can be used directly by users and can not be cleaned. The filling Relevant Steps amount of lubricating grease shall be 30% – 60% of the volume of bearing and bearing box, and shall not be too much.
During the installation of Koyo imported bearing, equal pressure must be applied on the circumference of the ferrule end face to press the Relevant Steps ferrule in. It is not allowed to directly knock the bearing end face with hammer and other tools to avoid damaging the bearing.
In case of mass installation, hydraulic press can be used. When pressing in, ensure that the end face of the outer ring and the end face of the housing Relevant Steps shoulder, and the end face of the inner ring and the end face of the shaft shoulder are pressed tightly without clearance.
When the interference is small, press the end face of the bearing ring with Relevant Steps the sleeve at room temperature, knock the sleeve with a hammer, and press the ring evenly through the sleeve.
The heating temperature range is 80 ℃ – 100 ℃, and the height cannot exceed 120 ℃. At the same time, Relevant Steps tighten the bearing with nuts or other appropriate methods to prevent the bearing from shrinking in the width direction after cooling, resulting in a gap between the ferrule and the shaft shoulder
The clearance of single row tapered roller bearing shall be adjusted after installation. The clearance value shall be determined according to different service conditions and the interference of the fit. If necessary, tests shall be carried out to determine. The clearance of double row tapered roller bearing and water pump shaft bearing has been adjusted at the factory, so it is not necessary to adjust it during installation.
the bearing must be installed under dry and clean environmental conditions. Before installation, carefully check the machining quality of the mating surface of the shaft and housing, the end face of the shoulder, the groove and the connecting surface. All mating connection surfaces must be carefully cleaned and deburred, and the unprocessed surface of the casting must be cleaned of molding sand.
Loosen the bolts fixing the bearing pedestal. Remove the bearing together with the bearing pedestal Relevant Steps from the shaft. Before removing the bearing seat at one end of the shaft, loosen the bolts of the bearing seat at the other end of the shaft to avoid damage to the bearings at both ends.
First loosen the locking screw on the bearing eccentric sleeve with an Allen wrench, then insert a small iron rod into the counterbore on the top cover eccentric sleeve, and loosen the Relevant Steps eccentric sleeve against the rotation direction of the shaft.
Many people use improper installation methods in the installation of IKO imported bearings, resulting in bearing damage. So how to install the bearing correctly? I hope you can have a more comprehensive understanding of the installation and disassembly of bearings:
For bearing rings with clearance fit, it is recommended to apply a thin layer of anti creep corrosion agent on the mating surface to prevent friction corrosion between the mating surfaces.
390000 series outer spherical bearings fix the bearing inner ring and the shaft through the eccentric sleeve, and the hexagon socket screw on the eccentric sleeve plays a fastening role. During maintenance, many operators cannot disassemble this bearing, so it is necessary to introduce the technical points and precautions for disassembling 390000 series outer spherical bearing:
Correct installation is very important for the use of IKO imported bearings. I hope you can use the correct installation method in the future.
During installation, mechanical, heating or hydraulic methods can be selected according to its type and size. The force exerted on the bearing during installation must not be transmitted from one bearing ring to another through the rolling element, otherwise the raceway may be damaged. However, under no circumstances should the bearing ring, cage, rolling element or seal be directly knocked.
