Replace them with 7202A5TYDUHP4's

Next option is to buy some relatively inexpensive 7202BYG"s and have them preloaded with about 390N by KAF in DF config by KAF Manufacturing is in Stamford, CT

Cheapest and last option is to ask KAF if they can preload the 6202's with 50-70 lbs preload in DF configuration. You WILL have to clamp the inner and outer rings TIGHT when this is done - forget the lovejoy idea - make the space and do it right.

NOTE: the preloaded 6202's won't/can't run as smoothly or as freely as the 7202's mentioned above - long story why.

These are THE options to "maximize" your accuracy. You can kluge together any number of other fixes but these are your best alternatives.
