The MIF-011 NB16 bearing set provides eight replacement bearings sized for Kyosho Mini Inferno and Mini Inferno ST chassis that reference the ACME NB16 designation. This kit is intended to restore low-friction rotation in hubs and drivetrain assemblies where bearings have worn.
Kit contents: eight pcs of NB16 bearings matching the NB16 form factor, suitable for models that list NB16 bearings in their parts breakdown. Use during scheduled service intervals or when diagnosing binding or increased drivetrain drag.
Workshop guidance: remove bearings with appropriate pullers or drift tools, deburr and clean seating bores prior to installation, press bearings squarely with a driver that contacts the outer race, then verify axle endplay and rolling smoothness. Proper fitment reduces mechanical drag and promotes repeatable steering and throttle inputs; this set is a service component rather than a performance upgrade.
Maintenance reminder: intended solely for hobby model use; confirm NB16 fit for your Mini Inferno variant, store bearings clean and dry, and apply light model-grade lubrication at the races as recommended.
