Product Description

Title Line

Our Weighing Bellows are made from our clear ether-based thermoplastic polyurethane alloy Seeflex 040E, making them very strong and flexible, so they won't fracture as a result of constant flexing.

The shape of the Weighing Bellows is ideal for preventing vibration transmission between equipment, minimising any transfer that can affect weighing or scales downstream. 

Snap-fit connector and spigot design ensure fast, accurate installation every time the connector is removed and replaced.

Application
  • Designed for applications where precise weighing is required, e.g. loss-in-weight feeders & dosing equipment.
