Looks similar to the 81-278 1-1/2" metal wheel in what appears to be a brass housing. They are for a kiosk door at a gas station, nothing fancy. I only need one but I figure I should do all four while I am there.

I agree this looks a lot like the 81-278. Just make sure that the height and width of the housing match what you need, in addition to the wheel diameter.
