Product Description
Here at The Rubber Company our stitched bellows are a cost-efficient alternative for testing and small production runs. These bellows are bespoke manufactured to any shape, size or quantity, in order to match your exact specifications. We also offer a wide selection of materials and coatings to ensure that the bellow is suitable for your application. The highly versatile nature of these bellows enable them to be used in virtually any application and working environment. It is worth noting however, that applications requiring a watertight seal will require a moulded bellow.
Our stitched bellows provide good abrasion resistance as well as a wide operating temperature range as standard. Depending on the chosen material our bellows can also offer additional; mechanical, oil, acid, alkali and weathering resistance. Don’t hesitate to get in contact with us if you are unsure what material best suits your unique requirements. Our dedicated team are on hand in order to ensure that you can always get the best bellows possible.
Alligator Fastening System
Aside from our bespoke manufacturing service, we can also offer alligator belt fastening for many of our stitched bellows. This unique system is incredibly quick and easy to work with, and enables us to join bellows of any size. It serves to provide uniform tension across the length of the bellow, while also creating an smooth joint.
As you can see from the example the fixing teeth provide consistent grip, even while under great tension.
This makes it a suitable joining solution for a wide variety of applications from conveyor and transmission belts to agricultural applications. The alligator fastening system is suitable for use on belting up to 13mm thick. Don’t hesitate to contact us for more information regarding alligator belt fastening.
