Re: stiff bearings [TANKS]

["Derek Engelhaupt" <tankme-at-gmail.com>]

If it's the ones I'm thinking about, they loosen up a little after a little use.  The grease inside them tends to harden somewhat after they sit awile.  Plus, once you generate some heat in them they move more freely also.  I have some like this in my drivetrain.

I just bought some flange bearings from the RC Tank Combat Superstore (aka www.surpluscenter.com ). I tried to save some money and got cheap ones. They came today. When I turn them by hand, the bearings are very stiff. They're certainly turnable, but they don't really rotate easily. I'm wondering if using them would result in a significant waste of power or if I'm just being too picky. These bearings are going on my driveshaft. I know it's hard to say without actually handling the bearings, but what do you think ? I can replace them with good quality bearings for $40 or so. Worth it ?
