158222-MK MK Blade Shaft Assembly
Ratings & Reviews
do a little home work.
The blade shaft I received did not have the notch in it for the lock button.
The bearings sent are cheep low quality junk, the plastic cover fell out, and the bearings are noisy.
I found hi quality precision sealed bearings at Ace for 12 dollars, and they run very smooth and silent.
Don't wast you money on this junk.
