32900 Series Tapered Roller Bearing

32900 Series Tapered Roller Bearing
ISUTAMI tapered roller bearing 32900 Series belongs to the separated type bearing. During the assembly process, the quality of the bearing material can be checked to identify the quality of the bearing.When the inner ring of the bearing is assembled on the shaft, in normal operation, if the bearing material is unqualified, the deformation of the inner ring will cause the deformation of the support or the change of the clearance, thus making the self-aligning roller bearing not flexible in rotation or the rolling body falling off.In addition, the bearing hardness value of 60 ~ 65HRC, above or below this value are unqualified.When testing the hardness of the bearing, the side of the inner ring or outer ring should be selected at the checkpoint to avoid damaging the bearing.During the test, the outer ring and inner ring of the bearing can be cut with a knife. If there is a noise of cluck and cluck, and no chips are left, the hardness is enough, and if there are chips, the hardness of the material does not meet the requirements.The improper installation position of tapered roller bearing will cause the axial force between the end face of the bearing and the inner ring and outer ring of the bearing seat and cause the bearing to overheat.It is better to use the specified precision level of the bearings.The solution to the heating caused by the bending of the bearing spindle in use or the different cores of the box holes is to repair the spindle.The solution to heating caused by too tight bearing belt is to adjust the belt to make it elastic properly.

32900 Series Tapered Roller Bearing Features

The solution to heating caused by poor lubrication is to select the specified brand of lubrication data and clean it properly.The solution to low assembly quality causing heat is to improve assembly quality.The solution to the heating caused by running rings of the inner shell of the rolling bearing is to replace the bearing and related wear parts, correct the diameter of the impeller balance hole and check the static balance value.The solution to heating caused by too much axial force is to clean and adjust the clearance of sealing ring.The rolling bearing damage caused by heat is the solution to replace the bearing.When we are in the use of tapered roller bearings, if it is found that the temperature is very high, is to stop the equipment running, and find out its reason, and provide solution for processing according to the above, but may be due to the reason of bearing heating is different, so the solution is also different, so still have to treat, particular case is particular to choose the appropriate solution.

When the bearings disassembled in the process of regular maintenance and operation of tapered roller bearing equipment and the replacement of peripheral parts are discontinued, it is required to judge whether the secondary bearing parts can be used again and record the application status.Secondly, the condition of raceway surface, rolling surface and joint surface of the bearing and the wear condition of the cage, etc., whether there is any damage or abnormal condition is special to check the track of the raceway surface.To judge whether conical roller bearing can be used again, it is necessary to consider the level of bearing damage, mechanical function, priority, operating premise, search cycle and so on.If the conical roller bearing is found damaged and abnormal, please find out the reason according to the phenomenon of bearing damage and make countermeasures.Tapered roller bearings are essential if they are to be used in harsh environments because they prevent contamination and extend bearing life.It is required to bear strong impact load, water and debris invasion.The negative pressure in the bearing can cause water to invade from the main seal.Therefore, the negative pressure in tapered roller bearing is the basic requirement to prevent water from entering.The most effective method is to make the hole seal is not in direct contact with water, while retaining the original function of the hole seal, prevent water and dirt from the side invasion.The sealing method USES the surface contact instead of the line contact, no matter in the running process or the static process, the surface contact hole seal has the good sealing characteristic.Therefore, the new super capacity sealed clean bearing has higher reliability than the traditional sealed bearing.Bearing in the lubrication condition, the load, and high reliability, long life, easy to maintain.This improvement in performance is the result of the optimization of mechanical design, the adoption of new materials and patented sealing techniques.
