Hello Gadge and Bonnar Bloke
Thanks for the info on the pipe etc, local steel merchant will sell me a metre but the id od and wall thickness they told me didn't make sense,if needed I was going to check it out.
As far as determining the durabilty of my modified bearing compared to the original I am way out of my depth there. When I initially looked in to doing it I spoke to the bearing supplier about using the bearing, I described where it was being used and the weight of the mower. Its all a bit too much me for me but from memory the static load rating of a 6202 bearing was well over 300kg. I have had a bit of a read and bearings subject to severe shock may also use different grades of steel to a normal bearing, whether the SB roller operates under severe shock conditions is debateable, I guess some people would use the mower as a battering ram when mounting kerbs etc.
You would think that bearing I use would probably have a lower rating than a normal 6202 bearing as it loses 1mm somewhere. Total "thickness" of a 6202 (inner, outer, ball race) is 9.5mm. A 6002 bearing total "thickness" is 8.5mm, if I am reading the chart correctly its load rating is close to 300kg, it is also 2mm narrower than a 6202.
How does the quality of the original bearing regarding materials etc compare to an NSK bearing ?.
Personally I think the 6202 bearing works fine, maybe there is a mechanical engineer on the forum who could give an educated answer.
