This is a custom-designed u-joint intended for use in conjunction with MR63ZZ miniature ball bearings.\r\n(ID 3mm, OD 6mm, W 2.5mm; https://www.aliexpress.com/item/Low-speed-bearings-MR63-Z-MR63ZZ-L-630ZZ-WA673ZZA-3x6x2-5-mm-helicopter-model-car-available/32749270077.html?spm=a2g0s.9042311.0.0)\r\n\r\nMy machine has recently encountered friction wear issues due to misaligned shafts, but I'm hopeful that this u-joint will resolve the problem and also offer some assistance to you!
