Hourglass Springs Product Range - Trelleborg IAVS

Unparalleled reliability and comfort. 

Designed and developed in the UK by Trelleborg Industrial AVS, the hourglass spring is the perfect alternative in secondary suspension. Unlike traditional units the hourglass is made from high grade, solid rubber to provide one of the most reliable products on the market.

Due to its solid nature, the hourglass delivers additional benefits such as reduced maintenance costs, long service life and improved ride characteristics, as well as expelling the need for complex air supply systems. 

It’s high load capacity and ability to accommodate large horizontal, tensional and conical displacement means that the hourglass spring is now the product of choice for major train manufactures and passengers across the globe are experiencing their most comfortable journey yet
