Bearing carrier type with the grease zerts ill try to get a pic of my shaft tonight i asked one guy on ebay to measure one for me that looks the same im just waiting for his reply...i found one identical but was only 17"
Not sure, if the grooved shaft will work though. Cant see why not, if the seals on the carrier are working, it'll just be extra "pockets" for grease to sit in.....
