INA self-aligning ball bearings axial clearance adjustments should be noted

Bearing life is the relationship with the care and maintenance is very important, because it pertains to the length of INA bearings life, productivity high and low. Maintenance of self-aligning ball bearings used for good, will bring a lot of benefits, for example, can bring about high production efficiency, producing more high quality precision products, maintenance can extend the life of the times once again purchase cost savings for you.
　　Adjustment gasket 1 method:
　　In bearing end cover and bearing block end surface Zhijian filled placed a group soft material (soft steel tablets or elastic paper) gasket; adjustment Shi, first does not placed gasket loaded Shang INA bearing end cover, side uniform to screwed tight bearing end cover Shang of screws, side with hand turning axis, until bearing scroll body and outer ring contact and axis internal no gap weizhi; then measurement bearing end cover and bearing block end surface Zhijian of gap, again plus adjustable heart ball bearing in normal work Shi by needs of axis to gap; this is by needed filled placed gasket of total thickness, And gasket ready to fill in between the bearing end cover and housing, and finally tighten the screws.
　　2 adjustment bolt method:
　　Circle pressure pressure on the bearing outer ring, by adjusting bolts pressure; pressure before adjusting, first measure the pitch adjustment bolt, and then slowly tighten the adjustment bolt, until such time as bearing no gap, and then calculate the adjustment bolt corresponding rotation angle. 1.5mm,INA pitch for example needed for the normal functioning of the bearing gap, then the required rotation angle adjustment bolt 3600x0.15/l.5=360; flip 360 adjustment bolt, access to 0.5mm-aligning ball bearings axial clearance, and then snap the gasket to be fixed.
Using ball bearings with grease lubrication of grease should be replaced in a run of 1500 hours, filling quantity of oil to be just the right amount, because the grease is too much or too little can cause fever INA bearings, fuel generally lies in 1/2~2/3 of bearing Chamber volume.
