AM Medius 348mm S3M Belt Pair White - Arrowmax AM-910038  [AM-910038]

Medius S3M 348mm belt pair for RC drivetrains

The Arrowmax AM-910038 AM Medius belt pair is supplied as two S3M profile timing belts for belt-driven RC vehicles and scale drivetrains. The pack contains two 348mm white rubber belts engineered to match S3M pulleys commonly used in hobby transmission setups.

These belts are used for timing and power transmission: they maintain synchronized pulley movement, permit tension adjustment for setup refinement, and the white finish aids alignment and inspection. Fit them in applications where the S3M tooth profile and 348mm loop size match your pulley spacing.

Installation is typical for belt systems: route the belt over S3M pulleys, apply a moderate starting tension, and perform a short low-speed verification to confirm tracking and load distribution before full-speed running. Incremental tension changes affect drivetrain compliance and handling, so aim for uniform span tension and prevent edge contact with pulleys.

This two-piece Medius belt kit is a practical spare or setup part for keeping S3M-equipped RC drivetrains timed correctly when a 348mm belt is required.
