This is a roller bearing that can be printed in one piece.
edit: needs improvement; see below.
The special thing about it:
It has less sliding friction than a roller bearing with cage.
This is archived through the central rolls.
Those let the inner and outer rolls roll on rolls.
This bearing can can take radial and axial force.
It should run under (axial) load so that rolling is ensured !
A preload would work to but than a zero clearnce print with post assembly is required.
(split the ring or better the center piece in two for that)
A little bit of unavoidable friction occurs at the slanted top & bottom retainers but this should'nt hurt.
(gears also have a tiny friction component)
This needs improvement !
My test-print fused together on the outer edge so hard that I broke the ring when I tried to break the outer rollers loose. At the same time the inner rollers where so loose that they almost slid out. Also the small diameter rollers didn't turn out round enough to roll - even under load.
There are a lot of parameter combinations that do not work.
Change one at a time.
Low roller nubers lead to the necessity of high bearing diameters.
High roller numers make the rollers small and lead to the necessity of high center piece diameters
( 8 to 12 rollers are good I think)
