Trelleborg’s boots with aspirator create a perfect seal for rack and pinion steering mechanisms. They are particularly used on HPS for which the air circulation is external to the rack. Designed to your exact requirements, our boots protect the steering gear from dirt debris or water, and support extreme behaviors such as extension, compression or bending stresses.
The additional feature, an aspirator, allows the two boots of the steering system to be connected with each other outside of the rack. The aspirator is welded thanks to an innovative process on a non-functional area of the boot allowing the boot to keep a normal behaviour when the steering is cycled on the vehicle. Having the two boots of the steering system connected with each other will help distributing the air and the internal pressure between both sides. The tube guides the air going from one boot to the other and replace the hollow found inside other types of HPS’ rack.
This boot with aspirator can be manufactured with standard or anti-snaking design.
Why Trelleborg boots with aspirator?
The Trelleborg Boots Technical Centre creates boots to your exact specification. Using innovative construction techniques such as Finite Element Method combined with different technologies for producing thermoplastic boots, we can create the shape of boots you need at the specifications you want from a local centre near you.
