The XRAY 931016 steel sealed ball bearings are a compact, reliable choice for keeping your RC drivetrain spinning freely. At 10x16x4mm they provide tight tolerances and steady operation for everyday track use and club races.
Manufactured to consistent tolerances, these sealed steel bearings block dust and grit while the supplied AeroShell Fluid 12 oil helps cut friction and wear. The sealed design reduces maintenance between service intervals.
These bearings fit a wide variety of RC kits and upgrades and are listed as compatible with the NT1. Their construction suits both intense laps and casual backyard runs where smooth rotation matters.
