Rod ends also known as heim joints or rose joints are a type of bearing used in oscillating assemblies to reduce friction. It consists of a bearing mostly spherical, in the eye-shaped head of the rod end housing with integral shank. The rod ends misalign axially and thus allows the machinery to work efficiently even under misaligned or oscillating conditions. The other advantages of rod ends are it helps in eliminating edge stress and the excessive stress caused by adjacent components within a working machinery. The rod ends can constitute of plain spherical, ball or roller bearing. The sliding surface of the bearing is mirror finished and hence it smoothly can rotate within the housing. The rod ends can be non-lubricating or self-lubricating. The non-lubricating rod ends are made up of steel and are used in applications which has shock loads, alternating heavy loads or static heavy loads. The non-lubricating rod ends are provided with grooves for lubrication. The self-lubricating rod ends which are maintenance free has a self-lubricating sliding surface in combination with steel. These rod ends are used in applications where the friction coefficient should be less and no re-lubrication facility is provided.

Rod Ends Market: Drivers and Restraints

The rod ends are used in wide applications like automobiles, aerospace, industrial machinery, construction, etc. as it supports a wide range of mechanical tolerances, which can boost the overall growth of the global rod ends market. The use of rod ends is cost-effective solution since it substitutes welded or more sophisticated assemblies, and is a major driving factor for global rod ends market. The properties of rod ends like robustness and less maintenance also contributes in the growth of global rod ends market.

The introduction of inexpensive, self-lubricating rod ends which do not require any re-lubrication or maintenance are anticipated to limit the growth of global non-lubricating rod ends market.
