Cautions for Installation of Spherical Roller Bearing

  The structure of the  Spherical Roller Bearing makes it have the function of self-aligning. It can bear not only radial load, but also biaxial load. It has strong impact resistance. Main Applications: Paper making machinery, steel rolling mill gear box bearing seat, rolling mill roll, crusher, vibration screen, printing machinery, woodworking machinery, reducer for various industries, etc. Many people do not know how to install the self-aligning roller bearings, for fear that the installation will not affect the use, and what matters need attention in the installation, Longma Bearing Professional Teacher to explain for you.

  
  About installation, you will think that there are professionals to install, they do not need to know too much, in fact, understand the installation process in order to better use. The following edition will explain how to install the self-aligning roller bearings for you.
  
  How to install:
  
  A Spherical Roller Bearing is assembled with a drum-shaped roller between the inner ring of two raceways and the outer ring of a spherical raceway. The curvature center of the raceway surface of the outer ring is the same as that of the bearing center, so it has the same aligning function as the automatic aligning ball bearing. When the shaft and shell are deflected, the load can be adjusted automatically and the axial load in two directions. The radial load capacity is large, which is suitable for heavy load and impact load. The inner diameter of the inner ring is a bearing with tapered holes, which can be installed directly. Or the clamping sleeve and the dismantling cylinder are installed on the cylindrical axis. The cage is made of steel sheet stamping cage, polyamide forming cage and copper alloy car cage.
  
  For self-aligning bearings, when the bearing with shaft is loaded into the box shaft hole, the use of intermediate installation ring can prevent the outer ring from tilting and rotating. It should be remembered that the balls of some size self-aligning ball bearings protrude from the side of the bearing, so the middle mounting ring should be concave to prevent damage to the balls. A large number of bearings are usually installed by mechanical or hydraulic pressure method.

  For separable bearing, inner ring and outer ring can be installed separately, which simplifies the installation process, especially when both inner and outer rings need interference fit. When loading the axle with the inner ring in place into the bearing box with the outer ring, attention must be paid to check whether the inner and outer rings are correctly aligned to avoid scratching the bearing raceway and rolling parts. Installation sleeve is recommended if cylindrical and needle roller bearings use inner rings without flanges or inner rings with flanges on one side. The outer diameter of sleeve should be equal to the inner raceway diameter F, and the tolerance standard for machining should be d10. Stamping needle roller bearings with outer rings are best installed with mandrels.
  
  Through the above explanation, do you have a more specific understanding of the installation of self-aligning roller bearings? In the process of installation, some things should be paid special attention to. In order not to cause unnecessary trouble, today's edition I will explain them to you.
  
  Four points for attention during installation:
  
  1. Installation of self-aligning roller bearings must be carried out in dry and clean environment.
  
  2. The self-aligning roller bearings should be cleaned with gasoline or kerosene before installation, used after drying, and ensure good lubrication. The bearings generally use grease lubrication or oil lubrication.
  
  3. When aligning roller bearings are installed, equal pressure must be exerted on the circumference of the ring end face to press the ring in, and tools such as pins should not be used to directly hit the bearing end face, so as to avoid damaging the bearing.
  
  4. When the interference is large, the bearing can be heated by oil bath or induction heater. The heating temperature range is 80-100 C, and the maximum can not exceed 120 C.
  
  After installation, aligning roller bearings should be tested to see if there is any abnormality. If noise, vibration and other problems are found, they should be shut down and checked in time. Use it after debugging is correct.
