The Main Difference
Both parts are replacement components for the same HiCart Plus Nesher equipment family, but they are not interchangeable versions of the same item. The helical gear is listed as being on the main shaft, which makes it the option to consider when the part you are replacing is the main-shaft gear. When the part to be replaced is a gear, this is the side to focus on. The flat belt is listed with its own type designation and width, which makes it the option to consider when you need a flat belt for the cartoning machine. When the part to be replaced is a belt, this is the side to focus on. The practical decision depends on which drive component your maintenance plan calls for.
Product Notes
ACG HiCart Plus Nesher Helical Gear on Main Shaft for Cartoning Machine

This ACG gear is identified as a helical gear for the main shaft of the HiCart Plus Nesher. The MPN W0340431AZ is a concrete part reference if you are ordering replacement components for cartoning equipment. Because the title names the main shaft specifically, this gear is the listed choice when the part you need is the main-shaft gear. What it won't handle is the belt side: it is a gear, not a flat belt, so it is not the item to choose when your maintenance task calls for a belt. For buyers who already know their cartoning machine needs a helical main-shaft gear, this part name and MPN make the selection straightforward.
ACG HiCart Plus Nesher Flat Belt Type E3/V,O/V,THK for Cartoning Machine 1.5mm W

The flat belt is the belt-side counterpart, listed as type E3/V,O/V,THK with a 1.5mm width. It also carries MPN BMECBLTC0058. This is the part to choose when your cartoning machine needs a flat belt with that type designation and width. On the flip side, because this is a belt rather than a gear, it cannot act as the main-shaft gear replacement. The title gives you a specific width and type code, which is useful if you are comparing belt options for a HiCart Plus Nesher cartoning machine. If your part need is a belt drive component, this flat belt matches the type and width named in the title.
Final Choice by Use Case
Choose the ACG HiCart Plus Nesher Helical Gear on Main Shaft when your cartoning line needs a main-shaft gear. Choose the ACG HiCart Plus Nesher Flat Belt when you need a flat belt for your cartoning machine. Both are replacement parts for the same machine family, so the final decision rests on the specific part your machine needs. If you are placing a maintenance order, stick to the part type that matches the component you are replacing.
