4.5mm (BB) Slewing Bearing
Description
4.5mm (BB) Slewing bearing intended for glue in place mounting. Slewing bearings are designed to support heavy but slow/oscillating loads. Greater capacity when loaded in compression. The inner/outer race surfaces are cleared in assembly by 0.3mm and do not interfere when mounted. 4.5mm version here: https://www.thingiverse.com/thing:3122654 Applying lithium grease to the BBs greatly reduces rolling friction due to the regular BB diameter but very capable. Inner and outer race can be printed at the same time by flipping one 180° so the large flat face is on the print bed. The 190mm was just a proof of concept and works well but needs an external support to maintain roundness. Diameters posted are just random assortment. If there are requests I'll gladly post them. Fitment Height = 6mm typical ID = Diameter - 10mm (Edit: was 5mm) OD = Diamter + 10mm (Edit: was 5mm) BB count = Diameter X 1.384 rounded
