I carry Timken Blue Brute Forestry Bearings. Stay away from Rexnord/Linkbelt bearings as they've changed the seal in them and they will go bad quickly. We're having great success with the Timken's. I had a Carlton SP7015 that had 600 hours on the bearings. The Timken bearings are sealed. You only give them one shot of grease per bearing every other day. The savings in grease will pay for the bearings.
Anybody can call me at 770-420-6400 and I'll give you my cell number to send me photos of your bearings. We'll cross them over to Timken's if possible. We do stock the Timkens for all Rayco's and Carlton's.
Hope this helps!
