Frequently Asked Questions

Can I buy screw conveyor parts and components from screw conveyor manufacturers?

There are several manufacturers of screw conveyor parts in the United States. (See more about manufacturers HERE) Most of these manufacturers put a lot of money into getting their name out there and trying to distinguish themselves as the best, cheapest, or whatever. The truth is, when it comes to screw conveyor parts and components all the manufacturers are making the same parts. (See more HERE) Where each manufacturer distinguishes itself is in customer service and technical expertise.

In addition to each manufacturer making the same parts, none of the major screw conveyor manufacturers will sell parts and components directly to a customer. They all sell through a distributor, like ScrewConveyorParts.NET (Shop HERE). So, when you see that great add for trough ends, hanger bearings and replacement screws from a screw conveyor manufacturer, keep in mind they are going to direct you to a distributor to buy, which is why you are better off to buy directly from ScrewConveyorParts.NET.

Can you help me size my screw conveyor?

Yes we can!  Send us the information on you application to gethelp@screwconveyorparts.net and we will help out.  You can also view our article on sizing a screw conveyor or download one of the manufacturer’s catalogs to help walk you through.  Keep in mind, the manufacturer’s catalogs are primarily centered around control fed conveyors and horizontal applications only.  Below are a few of the items we need to help size your screw conveyor.

Material being conveyed?

Is the inlet control or flood fed?

Desired rate? (CFH or PPH)



Is ScrewConveyorParts.NET a screw conveyor manufacturer?

We are not a manufacturer, we are an independently owned and operated service provider and not affiliated with any manufacturer or distributor.

Do you have a customer service hotline?

Yes, In a way.  You can email us at gethelp@screwconveyorparts.net or call at 682-231-1228.  We would love to help you with your screw conveyor needs.

Do you sell 3" diameter screws?

For most screw conveyor manufacturers, 6″ diameter is the smallest cost effective size that can be manufactured.   Many traditional screw conveyor manufacturers can make 4″ screw conveyors, but anything below that usually requires special tooling.  In addition, CEMA does not standardize below 6″ screws.  Because these smaller screw tend to be in specialty applications, and therefore cannot be standardized we do not offer them.  There are a few companies that do make these smaller screws.  Auger fab has done a good job in the past and would be a good source to look at.  Their website is https://www.all-fill.com/auger-fabrication/.

Do you offer a plastic screw 30" dia x 8' long for a food application?

That is a tough one. We are not sure of anyone who can make a 1-piece plastic screw that big.

The best we have seen is the plastic flights that slide on the shaft, but we don’t think anyone makes them to 30″dia.

You would have to have a custom extruder company help and unfortunately we do not currently work with one.

Sorry we can’t be of more assistance.
