Superblend barreled bearings - the myth goes on....

I noticed in a feature of the October edition of Roadholder barrel-shaped Superblend bearings get a mention.

Purely in the interests of technical accuracy please note barrel roller bearings were never fitted to Commandos - and here's why. First off - barrel roller bearings have the rollers assemled to the inner race - the opposite of NJ306E's. Second - with the inner races fitted to the crank and the outer races fitted to the cases it would be impossible to assemble the crank to the cases because the inner and outer race bearing track is curved to match the barrel rollers, so there would be no way the two components could slide together in an axial orientation.

With NJ306E's fitted it is only possible to assemble these because the rollers and inner and outer race bearing tracks are parallel to each other - not curved as in the case of barrel roller bearings.

Call NJ306E's barreled superblends if you want - but you might as well state the sun goes around the earth.....which is flat.
