These Stud Type Track Rollers have been designed for specific use on track type or cam-controlled equipment when cantilever mounting is desired. They are corrosion protected, grease lubricated and, typically, sealed.

The stud type airframe track roller is selectively heat treated to provide a combination of a fracture tough head, ductile shank, and a carburized raceway to provide high load carrying capacity. External surfaces are plated with cadmium to provide corrosion protection and thread lubricity.
