ABEC 7 hybrid ceramic motor bearings.   1 ea: 4x13x5mm & 1/8x3/8x5/32" Tekin motors 2 ea: 1/8x3/8x5/32" for most all others including Trinity, R1, etc.   *Greaseless: No more wondering if all the thick grease is cleaned out. *No-contact rubber shields: Like using an open, shield-less bearing but with the protection of rubber shields. *Spin quiet, smooth, & longer than others I’ve tested. *Cleaned to ensure any manufacturing debris is removed & lubed with XCEL bearing oil.
