What are the technical requirements for rolling bearing?

Rolling bearing manufacturers with rolling bearing could save babbitt materials melting, casting and scraping tile and a series of complicated its high technical requirements of the maintenance process and oil supply, water cooling system, thus greatly reduce the amount of maintenance. And rolling bearing because is made by professional manufacturers, the quality are guaranteed. Also use manufacturer has brought convenience to the ball mill. Select the type of the rolling bearing in the rolling bearing manufacturer, should consider the working load bearing ( The size, nature, direction) , rotational speed and other requirements. Rolling bearing manufacturer under normal circumstances, the larger the installation of the bearings, not by heating the bearing or bearing is impossible, because with the increase of the size, the greater the force needed for the installation. Heat installation needed between the bearing ring and the shaft or housing, the interference temperature mainly depends on the quantity and the diameter of the bearing fit place. Open type bearing heating temperature shall not exceed 120 ℃. Bearings with seals and dust cover is not recommended be heated to above 80 ℃ ( Shall ensure that the temperature does not exceed the seals and the allowed temperature grease) 。 Bearing heating, uniform heating, never can have local overheating. In addition to economy, repair of bearing and its technical, which requires the repairer fully understand the bearing corresponding technical requirements, and bearing and its components on the structure, process, and the characteristics of the material, otherwise it is difficult to guarantee the effect of bearing repair is required. Manufacturer to remove the interference fit of the outer ring, rolling bearings in advance in setting several outer shell on the circumference of a circle of extrusion screw with screws, one side equal to tighten the screw, remove. The screw hole cover usual blind plug, the separation of tapered roller bearing type bearing, shoulders set several incisions in the shell, using block, remove by press, or tap the disassembly. Cylindrical hole bearing down, and the inner ring of disassembly, can use simple mechanical pull out new pressure. At this time, must pay attention to the inner ring under the pulling force. Remove the oil pressure method is used to large bearing inner circle. By setting on the axis of hydraulic oil hole, in order to make easy to pull out. Width of rolling bearing is oil pressure method and drawing fixture and disassembly operations. NU, NJ cylindrical roller bearing inner ring remove can take advantage of the induction heating method. In a short time heating the local, make the inner ring expansion after drawing method.
