Temperature of the INA roller bearings, high temperature is often said that the bearing is in an abnormal situation. The high temperature is also harmful to the lubricant of the INA roller bearings. Sometimes bearing overheating can be attributed to the bearing lubricant. Bearing more than 125 ° C temperature long-term even move to reduce bearing life. The factors that cause high-temperature bearings: lubrication or over-lubrication, lubricant impurities, the load is too large, the INA roller bearing wear, lack of space, and high-friction oil seals produce.
Therefore, continuous monitoring of INA roller bearing temperature is necessary, whether it is the bearing of measurement, or other important parts. If you are under the same operating conditions, any temperature change has failed.
Sweden INA roller bearing raceway groove sound and its control method sound operation of the bearing, move the body in the raceway surface of the move and issued a slippery continuous sound, unique bearings will all move sound. Bearing sound equal to the raceway sound coupled with the other sounds. The ball bearing raceway sound is irregular frequencies above 1000Hz, its main frequency does not vary with speed change, but its total sound pressure level increased with the accelerated speed. Bearing raceway sound, the raceway sound of the sound pressure level is reduced with increasing viscosity; raceway sound small bearings, its sound pressure level increase in the viscosity to about 20mm2 / s or more, by reducing into some increase.
Bearing rigidity greater the total sound pressure level, the lower raceway sound. If the radial clearance is too small, the raceway sound pressure level and frequency will follow the radial clearance to reduce sharply increase. Control raceway sound: selection of low-noise bearing waviness small bearings, carefully choose to use the premise. The raceways sound often affect the mechanical noise, reduce the the raceways sound can reduce the mechanical noise.
INA roller bearings jarring sound and its control method jarring sound is a cylindrical roller bearings in all occasions that may occur harsh and impolite metal friction sound, mostly took place in greased large models bearing oil in the base function more susceptible to deterioration of the grease in, and almost no oil lubrication. In addition, during the winter are more prone to easily occur when under pure radial load, radial clearance big occasions and with different model size, easily occur in a particular speed range, both on a continuum will intermittently thrown. INA roller bearing outer ring raceway to take special processing methods to prevent the jarring sound of the boom, these bearings can be used when necessary, or appropriate to reduce the radial bearing clearance, use the function excellent grease and progress with the bearing to match parts of the rigidity.

Vibration damage to the INA roller bearings can be said to be commensurate with the sensitivity, flaking, creasing, corrosion, cracks, wear, etc. will be reflected in the vibration measurement of the INA roller bearings. Therefore, can be measured by using a special bearing vibration measuring the size of the vibration frequency distribution inferred the exception of the specific situation. The measured values ??INA roller bearings use the premises or sensor installation location is different, so identified in the prior analysis of the measured value of each machine to determine the scale.Temperature of the INA roller bearings, high temperature is often said that the bearing is in an abnormal situation.
