All-O-Matic 40NP325 Drive Shaft Sprocket Chain (#40)

Replacement #40 Drive Chain for All-O-Matic Swing Gate Operators The All-O-Matic 40NP325 is a #40 drive shaft sprocket chain used in older All-O-Matic SW-350DC swing gate operators. Located within the operator’s mechanical drive system, the chain connects the drive shaft sprockets and transfers movement through the assembly as the gate opens and closes. This part is intended for earlier SW-350DC operators that use the 40NP325 #40 chain. It is not the correct chain for the newer SW-350DC Pro, which uses a different drive shaft chain. This distinction is important when servicing an existing operator because the SW-350DC name has been used across different generations with different drive components. The 40NP325 is useful when replacing an original drive chain that has become worn, stretched, damaged, or otherwise requires replacement during drive system service. Confirm the part number used in the existing operator before ordering, particularly when working with an SW-350DC of uncertain age. Key Features #40 drive shaft sprocket chain for the mechanical drive system Designed for older All-O-Matic SW-350DC swing gate operators Connects the sprocket components within the drive shaft assembly Transfers mechanical movement through the operator drive system Replacement for a worn, stretched, damaged, or missing original chain All-O-Matic part number 40NP325 Technical Specifications Manufacturer: All-O-Matic Part Number: 40NP325 Product Type: Drive shaft sprocket chain Chain Size: #40 Application: Swing gate operator drive system Compatible Model: Older-generation All-O-Matic SW-350DC Not Compatible With: SW-350DC PRO Installation Location: Drive shaft / sprocket assembly Function: Transfers mechanical drive between sprocket components Quantity: One drive shaft sprocket chain Conclusion The All-O-Matic 40NP325 is the #40 replacement drive shaft sprocket chain for older SW-350DC swing gate operators. Because newer SW-350DC Pro operators use a different chain, verify the operator generation and existing part number before ordering to ensure the correct drive component is selected.
