Boca Bearings vs. Acer bearings...ceramic sets.

[wallot]

higher ABEC rating more precise the bearing is and has higher chance to die when dust gets in.
ACER bearings are not bad but are not really dirt/water friendly. Had a set on my mugen and after 4 races half of them died.
I stick to cheap (like 60cents) ABEC 3 steel bearings and will try stainless steel this year that cost like 70cents. They last suprisingly long. of course they are not as smooth as Acer, but i at least remove the grease and put acer bearing oil in.

so i went back and forth on this and after reading up found that the ABEC rating does not mean they are faster. just means tighter tolerances. also, i talked the ebay seller down to $125 on the boca bearings and then found out they were a full-contact seal instead of no-contact seal like Acer so i just went with Acer. i have never had issues with mine. never failed and very smooth and fast. plus i just clean them out every so often and use the Sin lube and that keeps em running smooth.
