I am responsible for the electrical systems at a sawmill. I am having trouble keeping the pot heads of smaller motors in good shape. The environment is very abusive. The smaller stamped sheetmetal ones get crushed within a few days and the normal cast ones don't stay much longer. Does anyone have any experience with any type fitting that might hold up?

Been there;
First of all you need to confirm whether the boxes are being damaged from mechanical contact or from vibration.
If mechanical damage the only thing I have seen that works is a guard of some sort. I have tried working with motor manufacturers to try to come up with something that is more "stout" but the fact of the matter is if your little peckerbox comes in contact with a forklift or a load on a crane it will loose.
If it is vibration, you should first contact your mechanical peers. If a motor is vibrating that badly that it is breaking the mounting screws for the peckerbox on the motor, something is mechanically wrong (which is also not good for bearings, shafts etc....). If this can't be fixed, a severe duty motor might be in order.
I post mainly to share what are now fond anticdotes of my experiences in the southern U.S regarding language and terminology.
As a Canuck when first travelling south I asked an electrican whether or not he had any "orange marrettes" with him. He looked at me like a waiter at crackerbarrel ordering a sandwich, and I looked at him wondering if he was really an electrician. Turns out in the south "wire nut" is the common term.
I also recall asking a production helper to go to the storeroom and ask for "a chunk of 1/2" redi-rod". 30 minutes later he told me that the purchasing manager had located some and it would take 4 days to ship. Little did I know that redi-rod is called all-thread in the U.S.
I had learned enough to know when ordering a strain relief for a pendant cable (the steel mesh kind that grip several inches of the cable) that asking the supplier for a horse **** probably wasn't appropriate (although here Canada this is the only thing I know to call them by.) I can't recall what the PC term for one is.
The funniest for me was trying to order anything from a drive through. They obviously couldn't understand me and I couldn't understand them whent they read it back. It was kind of like a lottery, normally I got a burger, fries and some sort of pop (soda) but was never sure until I ate it.
Same continent, same language, same industry, same PLC's, but challenging and fun nonetheless.
No disrepect intended at all for any of my friends from the south, just observations.
