fault housing and bearing

i got the problem with housing and bearing . they are all totally damaged .Type of the bearing : spherical roller . At first , i checked with the tool to took the reading with vibration and enveloping acceleration . it look like machinery condition checker pen . Sorry i  do not tell the name of the tool . The Recorded reading been collected seem ok . Actually  when i opened the housing , the condition of housing seem seriously damaged .

as we seen the vibration at the feet of housing : 6.2 mm/s + Enveloping acc :2.1 gE .

thanks

Dear vishal sharma . it's 3600 rpm .  the contaminated grease could not because the client not change type of grease  . What i could explain : the rotor is unbalanced   and make the vibration , so on ...  In fact   i do not understand with reading been collected .

As Iso 10816 with motor 3600rpm , the bearing seem normal condition. not any doubt the condition of the bearing . So trust absolutely  the  standard or our feeling about machinery ?

 

I know what the tool is and that gE level would be high enough to warrant an inspection, were you able to grease the bearing mid reading? Ideally that tool is ok for assisting in greasing and less critical plant assessment, I wouldn't use it for high criticality machines your better off with a SKF Microlog in that case. 

Hi Husky,

Just to share some knowledge abt  tool that u use, SKF CMAS100.

Default setting for Enveloping (CL2) reading is for shaft diameter OD 50-300mm & machine speed 500-1800rpm. In that your case is machine speed of 3600rpm, this vibr pen is not suitable.

As for my experience, I am not using vibr pen for Enveloping measurement because it will not give either precise nor accurate reading. For vibration (velocity mm/s) is ok.

Try ADASH vibr pen for more enhanced features.
