For over a century, the Griffin® wheel brand has been at the forefront in wheel design, manufacturing innovation, and reliability. Now an integral part of Amsted Rail®, Griffin is making an even stronger commitment to industry-leading safety and innovation. The latest advance is Griffin’s patented Micro Alloy® wheel which is already setting the standard worldwide by providing greater strength at higher temperatures, resulting in fewer wheel-set removals and dramatically longer wheel life.


A real workhorse that can stand up to today’s demanding heavy haul services around the world, the AAR Standard One-Wear wheel is the go-to choice for proven reliability and durability. AAR Standard One-Wear wheels are available in 28″, 33″, 36″ and 38″.
