Default Trex 500 and 450 bearings in the bearing block question

Hi,
Anyone know how long the bearing block bearings should last? These are the ones the main shafts run through. My 500 doesn't seem to have lasted that long as it has a grinding roughness taking place when you manually turn them. Also I have oiled them in the past but wondering if that thinned the original lube making them wear more. Should they not be oiled? Thanks

I have the original bearings in my 500 & it's 2years old. Bearings are holding up fine. I lube them on a regular basis every 10 hrs of flight or so
My 450 have been replaced several times to to crashes started grinding after them. My 500's could be next took a couple of dirt naps latetly. If they start to go will upgrade to metal bearing blocks with new bearings. Good excuse to spend money LOL

Thanks for the info. What do you use to lube them?
