INA, a brand within the Schaeffler Group, manufactures rod ends, also known as spherical plain bearings or heim joints, which are mechanical articulating joints used to provide articulating motion between two connected components. Rod ends typically consist of a spherical plain bearing, a housing, and a threaded or welded stud or shaft. These components allow for angular misalignment and accommodate both radial and axial loads. Here are some common types of INA rod ends:
Female Rod Ends: Female rod ends have a threaded hole in the housing and are designed to be attached to a mating component with a threaded rod or bolt. They are commonly used in linkage systems, control arms, and hydraulic cylinders to provide articulating motion between connected components.
Male Rod Ends: Male rod ends have a threaded stud or shaft protruding from the housing and are designed to be inserted into a mating component with a threaded hole. They are commonly used in applications such as linkages, suspension systems, and steering linkages to provide articulating motion between connected components.
Maintenance-Free Rod Ends: Maintenance-free rod ends feature self-lubricating spherical plain bearings with PTFE liners or other low-friction materials that eliminate the need for relubrication. These rod ends are suitable for applications where maintenance access is limited or where lubrication is impractical.
Steel-on-Steel Rod Ends: Steel-on-steel rod ends feature a spherical plain bearing with an inner ring and outer ring made of steel. They are suitable for applications with moderate to heavy loads and provide high strength and durability under demanding operating conditions.
Corrosion-Resistant Rod Ends: INA offers corrosion-resistant rod ends made of stainless steel or with specialized coatings to protect against corrosion in harsh environments. These rod ends are commonly used in marine applications, chemical processing equipment, and food processing machinery where corrosion resistance is critical.
High-Performance Rod Ends: INA produces high-performance rod ends with advanced design features such as precision machining, low-friction coatings, and high-strength materials to provide superior performance and durability in demanding applications such as motorsports, aerospace, and industrial machinery.
These are some of the main types of INA rod ends available, each designed to meet specific application requirements and provide reliable articulating motion between connected components in various industrial and automotive applications.
