I think this is a USA made unit but I can't find any brand name on it
anywhere -I've installed brand new bearings, the previous user had
neglected to grease it so the bearings got destroyed - this is one that is
greased through a plug in the back that unscrews - I've greased it with some
high temp wheel bearing grease. photo on request (contact me at the email
address shown on my web page, please)
