Actually , the bearing install on shaft without sleeve.
Bearing type: spherical roller bearing
Bearing No. 22214E/C3
My question about diameter shaft what is min/max to be tight fit with bearing?
I attached similar picture of split bearing but it’s without adapter beqring directly install...
Bearing Replacement:
Two split block bearing use for Force Draft Fan
measuring shaft OD = 69.97 mm
spherical roller bearing 22214E/C3 use on Split Roller bearing.
what is the clearance between the shaft and Inner race for Spherical Roller bearing...
I have some inquiry about Mechanical Seal in Petrochemical.
most pump that we have 2 for each Tower(under Vacuum) one running another one standby. My Question
What is the best practice for standby pump that has Gas Seal (N2). Seal Plan 74
1- Keep N2 online all the time.
2- Isolated N2...
question about the function of Throttle bush in Single Seal plan 32 :
1)does it prevent leak or to reduce the leak?

vibration overall
change because the shaft bent that increase vibration, Runout 0.25 mm
direct coupled
anti-friction
Cylindrical roller bearing / double-row
vibration Reading Min 4.0 mm/s and max 5.3 mm/s (peak) that means overall
Axial Measured around the face of plummer block
we have change the shaft and impeller for FD Fan after start up vibration in Axial Direction for None Drive End Bearing 4.5 to 5.2 mm/s. and temperature of Drive End (Plummer Block Bearing) 70 to 80 Celsius while None Drive End 55-68 celsius . what do you think the reason of increase the...
