This steel ball rod end is designed to allow pivoting in the housing to compensate for misalignment in industrial applications. It features a precision hardened 52100 steel spherical ball, a 1045 carbon steel body, and a molded nylon/PTFE composite race. The self-lubricating design helps make it ideal for low to moderate load applications where part lubrication is not desirable. Note: Not for automotive or aircraft use. This listing is for each one.
