Maintaining the bearing is a necessary condition for the operation of the tapered roller bearing. The common maintenance is to lubricate the IKO bearing . When reading how to select the lubrication method of the bearing, under the premise of understanding the lubrication mode of the bearing, it is also known to the maintenance of the bearing system. It is necessary to let us see how to carry out bearing lubrication maintenance. 1. Keep the bearing lubricated clean Before inspecting the tapered roller bearing, the surface of the bearing should be cleaned first, and then the oil seal of the bearing and its surrounding parts should be carefully inspected. If there are any bad symptoms, be sure to replace it. The bad oil seal will cause damage, making IKO The bearing cloud is not normal and the equipment is shut down. 2. Pay attention to cover exposed bearings When inspecting tapered roller bearings, do not expose the bearings to contaminants or moisture. If the work is interrupt...

Nowadays, the requirements for the use of steel structures are getting higher and higher, so the requirements for the adoption of materials for steel structures are getting higher and higher. Which materials are mainly used for the use of steel structures, depending on the use, the components are different. The materials used are also different.       Main component materials:       1, sliver board: thickness 8-32. 180-600 wide. It is 15,000 or less in length.       2, the coil: open the flat plate, open flat plate. Generally wide 1250.1500.1800.2000. The thickness is 16 or less.       3. Hot rolled medium thick plate.       4. H-beam: hot-rolled H-beam, high-frequency welded H-beam.       Sub-component materials:       1. I-beam, channel steel, angle steel (equal, unequal), round steel, rebar, etc.       2, cold-formed hollow steel: square tube, rectangular t...
