Serpent 440163 Ball bearing 8x12x3.5 for Mini Spyder MT (4 pcs)  [SER440163]

Replacement ball bearings for Mini Spyder MT

This item is a set of four 8x12x3.5 ball bearings designed as direct replacement parts for the Serpent Mini Spyder MT platform. It is an RC-scale accessory intended to restore or maintain smooth rotation in wheel hubs, differential assemblies, and other rotating drivetrain locations where 8x12x3.5 bearings are specified.

Compatibility is focused on the Mini Spyder MT chassis; use these bearings where the original bearing size matches 8x12x3.5. The set includes four pcs, suitable for replacing worn bearings during routine maintenance or after exposure to grit and wear from off-road runs.

Installation and tuning notes: these bearings are used as drop-in replacements in hubs and diff carriers that accept 8x12x3.5 bearings. Ensure the bearing seats are clean and free of debris, verify proper seating and rotation after installation, and replace bearings in matched sets when possible to maintain balanced drivetrain performance. Regular inspection and light lubrication will extend service life under typical RC use.
