Review on 🔧 Enhance Power Transmission with Uxcell Groove Bearing Double Bearings by Johnny Nguyen

Need friction free spool holder bearings for my 3D printer. Once installed on the parts I printed, it was immediately clear that they would do the desired job of removing the stress on the motor to pull the weight of the coil to its previous position as it interacts with the plastic on the plastic's friction fought. And it came in a 4 pack so I have backups!
