I’m preparing to do a restoration on a Makita 2040 15” planer.
I’m wondering if it makes sense to upgrade the cutter bearings to ceramic ABEC class 7 bearings.
They are $68 each at as opposed to $2 each for normal bearings.

Would the repetitive impacts of 15” blades hitting wood quickly downgrade the bearings from ABEC 7 to 1 and below?

Is there so much inaccuracy in other parts of the machine that it would eclipse any benefit derived from these expensive bearings?

Is this a trick question? :)

I vote for replacing the same type of bearing. If you could downgrade I’m sure the manufacturer would have in the first place.

The planer is about 30 yrs old but with some TLC, I’m hoping it will easily get another 30 before having to tear it down again.

I didn’t think it would make a noticeable difference, but I read of some other woodworkers who replaced their jointer and planer bearings with ABEC 7’s so that’s why I asked.

VXB also has some sealed NACHI bearings which I presume are of better quality than the $2 ones, but still very affordable at $6. Still cheaper than what eReplacementParts wants for the oem replacement ($14).

There’s a difference, but I doubt you’d ever notice it.

Good place to save a few bucks !

I am in the business. The ceramic balls are generaly for supper quit operation due to their sphericity. Over kill for what you need, howerver; I would go with something better than a $2 bearing. Stick with domestic if you can, much better than the imports from the cheap labor countries.
