There are so many different types and makes of pillow block bearings, im getting confused and worried I will buy the wrong thing again....

Can anyone sugest a suitable super strong bearing and a good supplier because the ones I have are useless because they have play in them and are giving me cause for concern.

I need a pair for the lower fan shaft on my craft (25mm shafts)

you can see photos of the shaft here: %2005/Viper%20093.jpg %2005/Viper%20101.jpg

Sorry for all the short questions recently, I am pushing to get this thing finished now
