I have failed sealed bearings in my MTD mower deck. I replaced the failed bearings with these bearings, 6204-2RS sealed bearings. It's an easy job and these bearings fit perfectly. Just keep an eye on the spindle components as you disassemble, install new bearings, and reassemble the components in the same configuration. There are two bearings per spindle and ordering two bearings fixes one spindle. Saved at least $25 by swapping out the bearings instead of the spindle. The original bearings were made in China just like these. The original bearings lasted 6 seasons and I expect they will.
