Serpent 402201 Belt tensioner shaft for Medius X26  [SER402201]

Belt tensioner shaft X26 overview

This Serpent 402201 belt tensioner shaft is an RC-scale replacement component intended for use within belt-driven Serpent Medius X26 kits. It is specified as a steel shaft part and serves the mechanical function of setting and maintaining belt tension inside the tensioner assembly, helping the belt run true and reducing slack-related drivetrain losses in electric on-road setups.

The part is aimed at hobbyists and technicians who need a direct, durable shaft for the tensioner sub-assembly. In the chassis it occupies the tensioner pivot position and works together with the tensioner pulley and mount to preserve belt alignment under load. As an aftermarket replacement, the shaft focuses on mechanical fit and material strength rather than cosmetic changes.

Installation notes: fit the shaft into the tensioner bracket and pulley stack following your kit's assembly sequence, confirm smooth rotation and correct belt run, and verify belt tension across full travel. This description treats the item strictly as an RC-scale kit part, refer to your kit manual or seller for torque values and any small hardware contents.

This shaft provides a straightforward steel replacement for the Medius X26 tensioner assembly, intended for builders and tuners who prioritise consistent belt tension and drivetrain reliability in electric RC kit environments.
