Is a slower rotation speed of the bearing better for its lifespan?
Thread Content
Our factory has some mixing equipment, and sometimes a \"clicking\" sound is heard at the bearings (the bearings are lubricated with grease and are deep groove ball bearings). Our seniors said it might be due to insufficient lubrication caused by low rotation speeds, but no significant increase in bearing temperature was detected.
The higher the rotational speed and the greater the external load, the shorter the lifespan
It’s possible that the noise isn’t caused by the bearing itself
The bearings of the mixing equipment are making some ‘clicking’ sounds along with lubricant leakage; this is not related much to the rotation speed. It should be checked whether the main shaft is aligned properly, or if there are impurities such as metal shavings inside the bearings.
If there is noise, it is usually because the bearing is worn out, or something has gotten inside the bearing
