introduction： Clearance is an important factor for the normal operation of bearings。Select the appropriate bearing clearance，The load can be distributed reasonably among the rolling elements；It can limit the axial and radial displacement of the shaft to ensure the rotation accuracy of the shaft；Make the bearing work normally at the required temperature；It can reduce the vibration and noise of the bearing during operation，It can be seen that，Bearing clearance vs. bearing life、Temperature rise、Vibration and noise have a great effect。In the selection of bearing clearance...

introduction：Rolling bearings are perishable，Excessive force or corrosion will greatly reduce its service life，So bearings need frequent maintenance，Bearing repair has the following types： １.The imported bearing is slightly damaged，For example, slight rust during inventory，As well as the slight slight caused by the transportation process...

introduction： The raceway sound is due tonskWhen the bearing rotates, the rolling element rolls in the raceway and generates a smooth and continuous noise，It attracts attention only when its sound pressure level or tone is extremely high。In fact, the sound energy stimulated by raceway sound is limited，As in normal circumstances，Of high quality6203nskBearing track sound is25～27db。This noise is applied to a single row of deep groove balls under radial loadnskBearings are the most typical，...

introduction： High precision design radial cylindrical roller bearings areHRBPart of the ultra precision series of Matsubei Seiko。The linear expansion due to rotation can be compensated by the float between the roller and the raceway，So they are ideal for floating end bearings。In addition，Radial cylindrical roller bearings also have very high radial yield。 Floating bearings are almost exclusively single-row bearings，Therefore, this product is widely used as floating bearings。In addition，It is also used for bearing devices with the following requirements： ●Radial stiffness ●high...

introduction：[Bearing knowledge]Large bearing imported bearing regular maintenance judgment method：
Large bearings cannot be rotated by hand，Pay attention to check the rolling element、Raceway surface、heeler、Fender surface and other appearance，The higher the importance of bearings, the more careful inspection is required。
1The resultant force is applied as far as possible through the axis of the imported bearing，This requires the point of application to be uniform, symmetrical and stable，Force is applied through a sphere or parallel to an axis。

introduction： Tapered roller bearings can be separated，By inner ring with roller、The components and outer rings of the cage together can be installed separately。The modified contact line at the contact point between the roller and the raceway reduces stress concentration。Tapered roller bearings can withstand large radial and axial loads。Because tapered roller bearings can only transmit one-way axial loads，therefore，In order to transfer the axial load in the opposite direction, another tapered roller bearing is required to be mounted symmetrically。 The most used tapered roller bearings are single-row tapered roller bearings。...

introduction： To judge the disassembledFAGWhether imported bearings can be used again，Check the bearing after washing。
Carefully check the raceway surface、Rolling surface、State of mating surface、The wear condition of the cage、FAGThe increase of bearing clearance and whether there is damage related to the decrease of dimensional accuracy，abnormal。Non-separation type small ball bearing，Use one hand to support the inner ring horizontally，Rotate the outer ring to make sure it is smooth。
Tapered roller bearings and other separate bearings，Can be on the rolling body、The raceway surface of the outer ring is checked separately。
