If there is a metal shield that prevents you from greasing them, then they are probably not the kind the need greasing. They are probably sealed to prevent dirt and grit from entering the bearing. Did the instruction suggest greasing them. I would think that rather than grease a light machine oil would be suggested. Good luck.

light oil you say? maybe tri flow or 3 in 1 oil?

I Googled "abec 5 bearings how to grease" and got much the same idea from a
number of sites:

The bearings are shielded cos they're sealed already.

Could it be you've simply come to the end of their useful life?

Have a look, anyway, and have a look at the other links provided by Google.


Happy s8g! ;-)
