I am looking to obtain a sample to prototype an application with potential for 20,000 units. Requirements in order of importance: 1) Thrust washer not to exceed 11mm diameter; prefer 10mm-8mm 2) Non-magnetic 3) Low friction 4) low noise/vibration Picture of bearing 51104 is what I want in 9mm ideally- this would be (2) nylon grooved washers with glass/ceramic/brass-bronze bearings. Thank you.
