Hello Julia
if you are an SKF rep and not a spam bot please tell us the design philospy behind the roller end radius on the skf NJ206 C3s fitted as OEM crank mainbearings to our bikes and explain their poor capacity to handle location and deflection misalignment simultaneously compared with other bearings half the cost.
would also love to know why the SKF group says they don't make NJ2206s in C4 but I have 2 in the bin
with reference to the big end bearing in the post you replied under, if you can find an SKF equivalent to an NTN PK 35 42 20 with an M section steel cage id like to know where I can get one.
if you're simply a nice person trying to help then thank you very much
have a nice day
