If you are going to design your own "this kind of device" (which the rest of us have no idea what is), why don't you start with establishing functional and dimensional requirements, and design it around a bearing that you select yourself and is commercially available?
All of the major bearing manufacturers have product catalogs and design guides. Be aware that part numbers in the catalog have wildly different availability, and that's why a chat with the sales desk at a local bearing supply place is warranted once you have a rough idea what you want.
That's a roller bearing, it could be caged or Torrington style. Not a great design for the application shifter support, roller bearings are designed for constant low-speed shaft rotation, I'd bet on them corroding in relatively short order (that's why all the notes about lubrication -- roller bearings need a grease fitting unless they are oil washed). A better design for a shifter support would be a precision-cut delrin or oilite bronze bushing.
There's plenty of motorcycle-application rolling-element bearings with intermittent motion. Swingarm pivot bearings. Rear suspension linkage bearings. Steering head bearings, although nowadays most of those are angular-contact ball bearings.

But roller bearings are very hard, designed for heavy rolling loads, and they like to roll. When used in a non-rolling application they tend to gum and stick. In the application OP posted, they're sliding over a shifter shaft -- I'd still prefer a machined bushing for better precision and because it is softer than a shifter shaft.
Aren't most steering head bearings "tapered" these days? IAngular contact is the type where each race cup is an opposed 1/2 round cup. The balls are round and run in a cage, sometimes loose like most pre-80s bikes.
I was told once that the ideal solution for steering head bearings is tapered roller in the lower and caged balls in the top.
Makes sense, the majority of the impact loads are in the bottom and balls provide lighter steering feel.
Please feel free to correct me if I'm wrong ?
