What should be paid attention to when installing and disassembling a full complement cylindrical roller bearing? Many people apply improper placement techniques in the placement of full complement cylindrical roller bearings, resulting in bearing damage. So how to correctly place the full complement cylindrical roller bearing? It is hoped that you will learn more about the installation and removal of bearings: when installing, you can choose a machine, heating or hydraulic technology according to their type and size. However, under any circumstances, the bearing ring, connection frame, rolling element or seal should not be simply knocked. The beneficial force applied to the bearing during placement must not be transmitted from one bearing ring to another through the rolling elements, otherwise it may cause damage to the raceway. Regarding the bearing rings with clearance joints, it is recommended to apply a thin layer of anti-cracking corrosion agent on the joint surfaces to prevent conflict erosion between the joint surfaces. Proper placement is critical to the application of full complement cylindrical roller bearings. It is hoped that you will be able to apply the correct placement techniques in future applications. The 390000 series outer spherical bearing is to fix the inner ring of the bearing and the shaft through the eccentric sleeve, and the hexagon socket head screw on the eccentric sleeve has the advantage of tightening. During maintenance, many operators will not disassemble and assemble this kind of full-complement cylindrical roller bearing, so it is necessary to introduce the technical points and precautions of disassembling and assembling 390000 series outer spherical bearings: installation 1. Before placing the full complement cylindrical roller bearing on the shaft, be sure to unplug the fixing pin of the bearing coat first, at the same time polish the surface of the journal to be smooth and clean, and coat the journal with oil to prevent rust and lubricate (allow the bearing to have a slight dent on the shaft). scroll). 2. Apply lubricating oil on the joint surface of the bearing seat and the bearing, and install the bearing into the bearing seat. Then put the installed bearing on the shaft together with the full complement cylindrical roller bearing seat. Push to the desired location for placement. 3. Do not tighten the bolts that fix the bearing seat first, so that the bearing coat can roll in the bearing seat. Install the other end of the same shaft in the same way and disassemble it. First, use an Allen wrench to loosen the locking screw on the bearing eccentric sleeve, then insert a small iron rod into the countersunk hole on the top cover eccentric sleeve, and loosen the eccentric sleeve against the torsional direction of the shaft. 2. Loosen the bolts securing the bearing housing. Remove the bearing from the shaft with the bearing housing. Note that before removing the bearing housing at one end of the shaft. The bearing seat bolt on the other end of the shaft should be loosened to avoid damage to the bearings at both ends.
