We have a centrifugal water pump, 2900 rpm speed. The water temperature is 20-30 centigrade degree. In original design (KSB Germany) this pump has two 6413 C3 bearing with 0.023-0.043 mm radial clearance. Now we can't find C3 bearing. Can we use CN (0.008-.0.028 mm radial clearance) bearing by change the bearing seat tolerance on shaft/housing? The shaft tolerance on shaft is 65k6 (+0.002, +0.021m) and in housing is 160K6(-0.021,+0.04mm).now we use induction heater for mounting bearing on shaft. Thank you

Interesting, I didn't know KSB made small pumps (the ones I've been "intimately" involved with are driven by 13,000HP motors). Why not call KSB and ask them directly?

I'd call a bearing company for an advice/replacement.
