1. On Wednesday, January 5th, I was assigned by Aj.Wuttichai to avouch to check all of
motors. There are about 30 motors we fixed, some of these can work as usual but some
can‟t work because of either damaged bearings or machine. Each of damaged motors has
different bearings, moreover there are 2 bearings in itself; the front bearing we called “OS”
(Single Lip) and the behind one we called “DS” (Double Lips). So I did need to note the
name of barring accurately.
There are 2 ways to check the name of bearings, those are
1. Advising the label which is stuck at the side of motor. It describes all the details.
„BAR‟ is written as Abbreviation of bearings, then I noted the name of bearings.
2. If the label doesn‟t tell me the name of bearings, I need to bare the motor for
seeing bearings within motor. Nevertheless I didn‟t bear it, I was helped by my
friends because I had no enough energy.
In second way, we observed which one is either front or behind by its vane. The part
has vane, it is behind.
That‟s all I have done today!
