Check the Raceway surface, rolling, status of the mating surfaces, wear of the cage, FAG bearings clearance increases and has nothing to do with precision drop damage, unusual. Non-separation of small ball bearings, the inner ring support level with one hand, rotate the outer ring to confirm fluency. Separation of [...]

  • Identifying method of rolling FAG bearings

    ⑴ identification of radial ball bearings  Technical condition of normal radial ball bearings,, Raceway in the outer ring should be free of flaking and severe galling, and light to a circular Groove; all balls must be kept round, without spots, cracks and spalling on the surface; cage does not loose, not broken, not worn. Dang with a only handheld within ring, another a only hand quickly light push outer ring rotating Shi, requirements rotating sm [...]

  • Proper use of spherical roller bearing grease effect on speed

    Correct use of grease, you must know the grease grease in the bearing movements. Ensure stability of lubricating grease. Fill in a spherical roller bearing grease campaign as the FAG bearings rotates and generally can be divided into two phases.In the General case, the filling amount of grease in the bearings, always exceeds the amount of directly involved in the actual needs of lubrication, cavity on the frame and bearing cover, and on the edge [...]

  • FAG bearing installation and maintenance methods

    FAG bearing applications where low-speed heavy working conditions, difficulties or maintenance and add oil the moving parts. How reasonably the FAG bearings installed and maintained it, usually to note which elements? FAG bearings maintenance must be paid attention to in the process cleaning, lubrication and so on a series of problems. A type of bearings FAG bearings are also very common, below I'll show you in a related knowledge, we hope to hel [...]

  • For FAG bearing grinding technology

    1, the basic requirementsShould make the shaft and FAG bearings even close contact, but also have a certain clearance.2, contact angle is defined on the contact surface of the center shaft and FAG bearings angle.The contact angle is not too big nor too small. The contact angle is too small will cause the FAG bearing pressure increases, serious when can make the FAG bearing large deformation, accelerated wear, shorten the service life; the contact [...]

  • How to prolong the service life of FAG needle roller bearings

    Needle roller bearings are precision components, when in use requires a very cautious attitude, which is the use of bearing high performance, if used improperly, can't reach the expected performance results, and it is easy to make the FAG bearings damage. So, should pay attention to the following items using the needle roller bearing:1, keep the needle roller bearing and the surrounding environment cleanEven the naked eye cannot see smile dust in [...]
