GORTEF supplies PTFE separator feed belt to fit the Bunting MASTEROLL, made to the dimensions you measure off your own machine. It is an aftermarket replacement rather than a genuine Bunting Magnetics Co. part.
The MASTEROLL is the Master Magnets rare earth roll, built with neodymium iron boron magnets in a composite high-intensity head pulley and sold by Bunting. Bunting publish the separation principle and not the machine sizes, so the roll width and the belt on your machine both have to be measured rather than looked up.

Which GORTEF Product Fits the Bunting MASTEROLL?
Confirming the Exact Specification
We are still finalising the published dimensions for this model. Send us the dimensions of the belt you are removing, or a photo of it alongside its packaging, and we will confirm the construction before you order. Measure the old belt itself where you can. Working back from the machine aperture or the roller centres gives a length that is close but rarely exact.
How to Order a Belt for the Bunting MASTEROLL
Measure the belt across its width and right around its length, and tell us how the ends are joined. We make PTFE belts endless to the length you measure and finish the edges to suit the way your machine tracks them.
If the old belt is already off the machine, measure it flat and send a photo of the join with your dimensions. The join type matters as much as the length for how a belt runs.
Check You Have the Right Machine
Model designations vary between regions and production years. To confirm the Bunting MASTEROLL is the machine you are servicing, check the manufacturer's own listing:
