Medius X26 Sleeve Bearing Insert for precise fit - Serpent 402204  [SER402204]

DJC Sleeve Bearing Insert Overview

This Serpent 402204 DJC sleeve BB alu is an RC-scale accessory designed to secure and align small ball bearings inside the Medius X26 steel EP (SER400052) chassis where sleeve-type bearing seats are used. The component is described as aluminium and gives a stable, wear-resistant seating for 1/10 electric touring car bearing locations.

In use the sleeve replaces worn or deformed bearing seats or lets you tune lateral play in suspension and drivetrain mounting points. Because it is a small aluminium insert, it tweaks bearing fit and free play rather than changing larger chassis geometry; correct sleeve fit can reduce slop and improve repeatable suspension movement under load.

Installation notes: clean the housing before fitting, press the sleeve evenly into the bore until it is flush, and confirm the bearing spins freely with no binding. For setup changes, proceed incrementally—small sleeve fit differences affect free play and rolling resistance, so verify handling on the track after each change.
