Weighing bellows are commonly used in the food industry as the flexible transition between mixers, feeders, and other machinery where accurate weighing is required. Designed to minimize any resistance created by vertical movement or vibration on the weighing/load-cells, they are commonly made from highly flexible, molded silicone rubber. Although molded silicone rubber is widely used, it does have two significant drawbacks for use as a flexible connection—very poor tear strength and a high price tag. Many customers have often experienced product failures using traditional weighing bellows during installation as one small slip with a screwdriver or hose-clamp can tear the material.
However, the new, patented BFM® fitting weighing bellows do not carry the drawbacks of its silicone counterparts, combining the easy snap-fit installation and seal of a BFM fitting connector with the strength and flexibility of BFM’s urethane-based Seeflex material.
