GORTEF supplies PTFE-coated fusing belts to fit the Oshima OP-900A, made to the dimensions you measure off your own machine. It is an aftermarket replacement rather than a genuine OSHIMA Taiwan Co. Ltd. part.
The OP-900A is the 900mm continuous fusing machine, listed by Oshima alongside the OP-900LA, OP-1000A and OP-1000LA. Belts are sized per machine rather than per range, so confirm which of the four you are running before measuring: the LA machines carry a longer table and a longer lower belt.
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 Oshima OP-900A
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 Oshima OP-900A is the machine you are servicing, check the manufacturer's own listing:
