Trackball problem, ending spin...Help plz.

Pages: (1/5) > >>

struby:

I have a Betson 3 inch trackball with a mouse hack, everything works fine, but with every spin, the trackball, towards the end of the spin, turns to a more counter-clockwise spin direction.

Should I lube the bearings, I have speed cream drops for my street luge bearings, or just WD-40?

MinerAl:

I'm not sure why it would start spinning any way but the one you pushed it, but lubing your bearings is always a good idea.

The conventional wisdom here is that WD-40 is for cleaning parts not lubing them.  If you have a product specifically for bearing lubrication, use that.  And let us know how it works!

This may be totally wrong, but you might be able to improve this by removing those little copper grounding tabs from under the bearings, as these angle the rollers slightly.  This would defeat the grounding of the ball, so do so at your own risk.  If you wanted to keep the ground strap, you could find some material to shim the other side of the roller (bearing) to the same height.

Then again, it could just be normal behaviour for a trackball with the 3 roller arrangement.  It's hard to believe that there isn't some directional bias as the ball begins to lose inertia.

alright thanks guys, I'll let you know how it works out.

I'd like to know too.
My trackball's bearing sometimes will not roll smoothly.

The same for my trando spinner, it sometimes made noises when it was spinning. I uses wd40 on that but it only helped a bit.

Which lubing is good for bearing?
