MS200T seals
Not sure about the MS200t but on Huski 272, I couldn't buy the thinner seal that was needed at bearing supply house and had to buy Huski. Pull the seal and hit a bearing supply house. They are the experts. There are online sources as well. I use SASbearings.com when I can afford to wait a few days for parts. Fast shipping and very nice to deal with.
