3 tips: How to judge there are safety hazards in bearing operation by watching and listening?

Bearing is an indispensable part in the mechanical industry, and the quality of bearing affects the operation performance of machinery.We usually is removed bearing for testing, Today FRB BEARINGS teach you new skills: How to judge there are safety hazards in bearing operation by watching and listening?

Observation: should open the bearing box on a regular basis, in order to visual check bearing and oil seal, check of the condition of the near the bearing oil seal to ensure that they are enough to prevent hot liquids or corrosive liquid, gas along the axis of seeping into the bearings.



Listening: it's a common way to identify irregular movements by listening.If the bearing is in good running condition, it will make a low whine sound.Sharp hissing, squeaking and other irregular noises often indicate poor performance of the bearing.The sharp squeak may be caused by improper lubrication.Improper bearing clearance will also cause metal sound;The dent in the raceway of bearing outer ring will cause vibration and make smooth and crisp sound.If the percussion scars caused by the installation will also produce noise, the noise will vary with the bearing speed;If there is intermittent noise, the rolling parts may be damaged.If there are contaminants in the bearing, it will often cause hiss.Severe bearing damage can produce irregular and loud noise.

As the most important rotating part of the machine, the cross roller bearing gives the effective power to the operation of the machine.Checking the failure reason of cross roller bearing in advance can effectively avoid the sudden stop of equipment and reduce the damage to machinery.In addition to watching and listening, in fact, we can also by touch to detect the strain of bearing, if the bearing in the long run more than 120 ℃ temperature will greatly reduce the bearing life.

The causes of the increase of bearing operating temperature are: insufficient lubrication or excessive lubrication, impurities contained in the lubricant, excessive load, bearing damage, insufficient clearance and high friction caused by oil seal, etc.At this time, we need to fully lubricate the bearing and check whether there are impurities in the bearing. After all, pollution will shorten the service life of the bearing.Learn more: http://www.frb-bearings.com
