Yes, a standard MR85 would be way too narrow for unresponsive play. This design uses a 4mm wide version of the MR85.
I had to have those made for me. The only way it would become more widely available is if other companies use them in their designs and had some produced too.
Yes, the Flying Lemon uses this bearing.
Here it is on top of a C bearing.
If there are any concerns about the longevity of such a small bearing, i have been throwing my lemon solidly for 6 months and there have been zero issues so far.
Something you might be interested in. It’s a small sacrifice in diameter going from 8 mm wide to 9 mm wide but 684 bearings are 4 mm ID 9 mm OD and come in both 2.5 mm width and 4 mm width. Makes them narrower and a little more flexible that A bearings.
I am kicking around early designs for a convertible that uses both widths so you can go responsive and unresponsive.
I had a 20-pack of the 4mm wide 684 delivered last week, but haven’t had a chance to design and print something to use them yet. Didn’t realize there was a 2.5mm narrow option too, good to know!
But wouldn’t Mr. 105 be weaker than Mr. 85?(This is a joke. Please ignore me).
Mr.105 would indeed be weaker than Mr. 85!
Y’all have no idea how happy I am that you understood that reference. I was 95% sure I was just going to sound like an idiot.
