Allomatic 4L400 (AX38) Replacement Belt for SW-350 AC

AX38 Drive Belt for SW-350 AC Swing Gate Operators

The Allomatic 4L400 drive belt, also searched as 4L-400 and cross-referenced as AX38, is a genuine OEM replacement belt for Allomatic SW-350 AC swing gate operators. This belt helps transfer motor power through the operator’s drive system so the gate can move through its open and close cycle with proper engagement.

A worn, cracked, stretched, or glazed belt can cause drive slippage, slow gate movement, noise, inconsistent travel, or a gate that struggles to complete operation. Replacing the belt with the correct Allomatic 4L400, 4L-400, or AX38 belt helps restore proper motor-to-drive power transfer in compatible SW-350 AC swing gate operator systems. Before ordering, confirm the operator model and belt number printed on the existing belt or listed in the operator parts manual.
