I am working on a public art commission in Norfolk VA, and have been researching stainless steel ball bearing swivels and spinner blades to make small shiny spinning objects that resemble twinkling stars from a distance. I am looking for a ball bearing swivel that will last outdoors for 4-7 years. It will never be submerged in salt water, but will see all manner of weather during the project's lifespan on top of a building.
I used Worth #2 ball bearing swivels initially, but noticed a reduction in spinning effectiveness after a couple days. Does anyone have an opinion to share on Worth vs. Sampo vs. SPRO ball bearing swivels? I will need 2,500 swivels in total, so the price/quality is a concern. Worth seems reasonable at about $.50 / #2 swivel.
Thanks in advance for your advice and insights!
Additional info for reference:
I am making small assemblies of two spinner blades (colorado, indiana, and french blades) that resemble propellers. I am using Worth spinner blades with various coatings and textures to create different sparkles of light. Two blades are placed opposite each other with a hooked snap in between. The assembly is bolted together with a 4-40 stainless steel screw and nut. A swivel is attached to the hooked snap and another hooked snap is attached to the stationary end of the swivel. This snap clips onto a cable with stoppers on either side to prevent the assembly from sliding.

Thanks for your reply. I will look into the size 3 and 4. I was thinking a larger size might offer lower spinning resistance due to the ball bearings being slightly larger and rolling better on the raceway. Your test of 23 ball bearing swivels is the type of experience and rigor I was hoping to find here. Thanks a bunch!
