welcome to corporate stupidity in action

They did not grease the motor when it had plain or unshielded bearings

Then they replaced them with shielded bearings and having been burned
by bearing failure, introduced a greasing schedule

It is easy to make fun of such people, but we make dumb mistakes of
our own


It is not always corporate stupidity. Where I use to work there was a motor that drove a 800 cycle generator. The 800 cycles was used during missile testing and was needed about two or three hours a week. The motor had greaseable bearings and as I remember the manufacturer recommended a couple of shots of grease every five years when the motor was used 16 hours a day. The PM schedule could be scheduled for daily, weekly, monthly , every three months , twice a year , and once a year. So what would you do? Grease the motor once a year? Or not ever grease the motor?
