Don't spin the bearings with air , especially steel.
Why not?
Don't spin the bearings with air , especially steel.
Without lubrication you can damage them.
It may not be any worse then running no shields and spraying with some kind of goose grease
It's not recommended as a procedure for bearing cleaning .
It don't cost anything , simply hold bearing so it won't spin and blow out cleaning solution rotate repeat.
If the bearings are installed and maintained properly is there any performance advantage to hybrid ceramic or full ceramic bearings for karts? Do you do just the read bearings or also the front hub/wheel bearings?
Ceramics in a jackshaft turning any faster to make it worth while?no, their main benefit is high speed capacity which karts do not come close to. most people wont maintain them well enough to be faster with them.
the first time people use them and clean them they have hurt them badly. between using oils on a sealed bearing to using compressed air to dry an unloaded bearings karters have found lots of ways to destroy bearings without knowing it.
Things to not do with bearings:
1. use oils instead of grease and not replenish it often. the bearing consumes the oil. once it consumes enough the bearing starts to be damaged.
2. pack the bearings with grease with your palm and fill it till it looks right. its not about keeping your hand clean or being in the wrong hobby. its about not getting dirt in your 1000 dollar bearings. Look up the bearings data sheet. it will tell you how much grease to use. use a syringe to fill. too much and the grease will churn and the bearing will heat up. it can't push the grease out of the way enough.
3. spin a bearing with compressed air to dry it. you are spinning the bearing with no lube unloaded. bad. just like spinning a motor unloaded it can cause damage.
I'm just wondering where this guy came up with $1,000 bearings. I put all new bearings in over the winter and spent about $120 total.no, their main benefit is high speed capacity which karts do not come close to. most people wont maintain them well enough to be faster with them.

I would imagine that most bearing manufacturers are deciding on lubrication for a length of use over a speed of use. I know that if I was a general bearing manufacturer that is what I would be doing. Otherwise people will come back on you that your bearings are junk. If I can prove that a person unsealed my bearing, took my grease out, and did anything else, then it isn't my problem anymore.I love it when the bearing industry spends millions on deciding
how much and what grease and what seal to use in a bearing
and then someone decides that ain't right.
A properly sized and rated and installed bearing has about
enough grease to cover 1/2 of the ball in the bottom of the race.
I'll probably get flamed.
