a) Bearing details:
Bearings of SKF make and with C3 clearance are used. Bearings are grease
lubricated.
Notes:
1. Bearing of SKF make or equivalent are used.
2. C3 clearances are used.
3. Axial running clearance shall be less than 0.45 mm for all above bearing
arrangements.
4. Maximum allowable temperature of bearing shall be 80
0
C.
13.4 Bearing temperature of antifriction angular contact ball bearing - Grease lubricated
bearings can be operated up to 80
0
C. Measure the bearing temperature with
thermometer placed over bearing holder (25400).
A sudden increase in temperature is an indication of danger and signal to investigate.
Occasionally when pumps are first started the bearing seems to run extremely hot.
This high temperature is frequently caused by oil seals and not because of bearing.
As soon as oil seal lips get seasoned, the temperature drops to normal.
13.5 Line shaft bearings:
Line shaft bearings (35100 and 35300). These bearings are made out of 25% Glass
filled Teflon or 25% Carbon filled Teflon. Clearances between bearing and shaft
sleeve/screwed coupling are as follows.
Minimum clearance = 0.5 mm dia.
Maximum clearance = 0.6 mm dia.
13.6
Line shaft bearings shall be lubricated by the liquid handled by the pump and need
no external lubrication unless otherwise specified.
