I have specified bearing fits in accordance with the fits recommended by the SKF catalogue. The housing I am using is made of aluminium alloy to material specification LM27
The bore & shaft dimensions are as follow:
housing bore dia tolerance
1) 80 K7
2) 52 K7
3) 47 K7
Shaft dia tolerance
1) 20 k5
2) 25 k5
3) 40 k5
Pl through light on whether I should go by the tolerance specified in the catalogue. If I catalogue tolerance is used, the gear set is producing noise.
I tried to tighten the tolerance using m6 fit on shafts. I can find there is considerable reduction in noise. Is it correct to give m6 in violation of the tolerance specified in the catalogue?
