STIHL Genuine 029 039 290 MS310 MS380 MS381 MS390 Case Bearing # 9503 003 0440

Here we have a Genuine STIHL Propriety Bearing which many of the saws will use two of like the 029 039 MS290, MS310, MS390. Others will need one of these only for the Fan Side of the Crankcase like the MS380 and the MS381
These Specialty Bearing are made for STIHL under license and are designed specifically for chainsaw use. They are for sure worth paying the extra for. What is unique is really the bearing cages which are a special hi heat polymer which will not damage your motor.
The same thing cannot be said for the steel cage bearing with all of their many rivets. They really do grenage your motor when they let go.
Cheap insurance to protect your asset if you ask me.
Here if you need one or two anyways...
You can do no better than Genuine STIHL Spare Parts.
