Needed custom SCS20UU linear bearing to hold my 3D printed BB core. The core is 3D printed and loaded with 4.4mm steel BB's. Oil hole on top lines up with core oiling hole. Use teflon lubricant then place plug in hole. Have fun and if you need mods done let me know. Also this bearing assy fits the hardware store 3/4" aluminium round tube.
