Saint-Gobain’s Rencol Thermoclad Bi-Metallic Tolerance Ring for EV Motors is a new tolerance ring that helps to improve the reliability and performance of electric vehicles (EVs). The ring is made from two different metals, which expand and contract at different rates when exposed to heat. This helps to minimize the thermal stresses that can cause problems with EV motors. The ring also has a higher tolerance for shock and vibration than traditional tolerance rings, which makes it ideal for use in EVs.
