Disassembly and installation skills of IKO bearings

1. Loosen the bolts securing the IKO housing. Remove the IKO bearing from the shaft together with the IKO housing. Note that before removing the IKO bearing housing at one end of the shaft. The bolts of the IKO bearing housing at the other end of the shaft should be loosened to prevent the IKO bearings at both ends from being damaged due to mutual interference. 2. First loosen the locking screw on the eccentric sleeve of the IKO bearing with an Allen wrench, then insert a small iron rod into the countersunk hole on the eccentric sleeve of the top cover, and loosen the eccentric sleeve against the rotation direction of the shaft. Many people use improper installation methods in the installation of IKO bearings, resulting in damage to IKO bearings. So how to install IKO bearings correctly? I hope you have a more comprehensive understanding of the installation and disassembly of IKO bearings: For IKO bearing rings with clearance fit, it is recommended to apply a thin layer of anti-creep corrosion agent on the mating surface to prevent frictional corrosion between the mating surfaces. The 390000 series outer spherical IKO bearing is to fix the inner ring of the IKO bearing and the shaft through the eccentric sleeve, and the hexagon socket head screw on the eccentric sleeve plays a tightening role. During maintenance, many operators will not disassemble and assemble this kind of IKO bearing, so it is necessary to introduce the technical points and precautions of disassembling and assembling 390000 series outer spherical IKO bearings: Correct installation is very important for the use of IKO bearings. important. Hope you can use the correct installation method in future use. When installing, you can choose mechanical, heating or hydraulic methods according to its type and size. The force applied to the IKO bearing during installation must not be transmitted from one IKO bearing ring to another IKO bearing ring through the rolling elements, otherwise it may cause damage to the raceway. However, under no circumstances should IKO bearing rings, cages, rolling elements or seals be struck directly. Installation 3. Install eccentric sleeves. First put the eccentric sleeve on the eccentric step of the inner sleeve of the IKO bearing, and tighten it by hand along the rotation direction of the shaft. Then insert the small iron rod into or against the countersunk hole on the eccentric sleeve. Hit the small iron rod with a hammer in the direction of rotation of the shaft. Install the eccentric sleeve firmly, and finally tighten the hexagon socket head cap screw on the eccentric sleeve. 4. Do not tighten the bolts that fix the IKO bearing seat first, so that the IKO bearing shell can rotate in the IKO bearing seat. Then tighten the IKO bearing housing bolts. Also install the IKO bearing and seat on the other end of the same shaft, turn the shaft a few times, and let the IKO bearing itself find the correct position automatically. 5. Apply lubricating oil on the mating surface of the IKO bearing seat and the IKO bearing, and install the IKO bearing into the IKO bearing seat. Then put the assembled IKO bearing on the shaft together with the IKO bearing seat. Push to the desired location for installation. 6. Before installing the imported IKO bearing on the shaft, you must first pull out the fixing pin of the IKO bearing shell, and at the same time smooth the surface of the journal, and coat the journal with oil to prevent rust and lubricate (allow the IKO bearing to rotate slightly on the shaft). ).
