"Nova Pot Bearings – Precision, Strength & Seamless Movement."
Nova Pot Type Bridge Bearings can be designed to support virtually any vertical load and accommodate rotation about any horizontal axis. They can provide horizontal movement capability in one or more horizontal directions or can be fixed, offering no horizontal movement capability.
Rotation is made possible by an enclosed rubber pad situated inside the steel pot. Under high pressures this pad develops fluid like behaviour. This allows the top part of the bearing to rotate with respect to the bottom part of the bearing about any horizontal axis.
Sliding bearings have a Teflon (PTFE) to Polished Stainless Steel sliding interface which allows for low friction translation. The sliding properties of PTFE are well known. Nova Engineering Works has undertaken in-house testing using PTFE and stainless steel samples identical to those used in our bearings. We have achieved coefficients of friction as low as 0.016 at a contact pressure of 26 MPa.
