suzuki ones are no better that others in the fact that if you buy the suzuki ones they are within spec. now the big problem with buying other ones is that they might not be fully round, exactly the correct size and made from inferior materials. however if you buy them from a reputable company and ask them to had sort (extra cost) you will get the perfect ones. this is also true of calliper and fork seals.

material can make a difference in critical components as to "crush" tolerance etc.etc but we are talking rocket science and medical equipment etc.etc.

as long as the oring forms a proper seal and is impervious to petrochemical then all is good.

marksman industrial and simply bearing are a good cheep source of bearings and seals.
