INA bearings rolling appearance if there is crack and creasing or corrosion, will attack like riveting as periodic vibration and rivet noise, and its period can be fixed with speed but mostly into the inevitable corresponding relation, the scar in the channel will continue attacks, the scar in the steel ball on the scenery and the noise with the device and smooth premise and inevitable shift.

This kind of noise to the temperance: when device a striking the bearing, the plastic bearings and shaft assembly then in housing after when INA bearing with inclined to avoid; Avoid bearing corrosion and inventory avoid shock vibration transportation; Use high viscosity of smooth fat.

There were rolling bearing such as dust foreign bodies, the periodic attacks the vibration and so-called dust sound, its vibration and noise full of volatile, and with little or no.

The dust of the temperance to sound: improve the bearing way to clean, device before the bearings, shaft, a hole and match parts tough qing shen hong clean; Weed out the foreign body in smooth agent; Improved seal of the plastic bearing; Prevent use material not pure or studded with foreign body to plastic frame.

Choose wrong, lubricants lack of lubricant or attack aging scleroma, can cause INA bearing vibrate and noise, and the noise is no rules. About this situation, choose suitable for as long as the smooth agent, adjust its smooth dose, extend the use of smooth agent life and reasonable change cycle.

First, check the INA bearing vibration in the work from peel, indentation, rust, crack, wear, etc, will be in the measurement of the bearing vibration reflect, bearing vibration on plastic bearing damage is very sensitive, so, by the use of the special bearing vibration measurement device (frequency analyzer, etc) can measure the size of the vibration, through the frequency points not that abnormal specific situation. Due to the measurement of numerical of bearing conditions of use or sensor installation position and different, you need to every machine in advance the measured value of the comparative analysis to determine the judgment standard after the.

Second, check the INA rolling bearing the sounds of the situation because even if has a mild stripping bearing damage, etc, also can send out sound and irregular abnormal sound, so use the machine can sound resolution, measured by the sound of the plastic operation of the size of the rolling bearing sound and sound quality for inspection, a preventive role in advance.

Third, to check the temperature at which the INA bearing drive if use of oil hole can direct measurement of bearing outer ring temperature, is more a suitable. Usually, the temperature of the bearing, the general basis of outdoor temperature plastic bearing that out. If the lubrication, installation of appropriate, the bearing temperature sudden will rise, can appear abnormal high temperature, then must stop operation, and take the necessary measures to prevent it.
