PHS10EC IKO Female Threaded Metric Rod End Bearing (PTFE Lined) - Right Hand Thread

Rod end bearings, also known as heim joints or rose joints, are mechanical articulating joints used to provide a connection between control rods and pivot points. These bearings are designed to handle a combination of radial and axial loads and facilitate smooth and precise motion transfer in a variety of applications.


Key Features of Rod End Bearings:

Articulating Joint: The primary feature of rod end bearings is their spherical, articulating joint, which allows for angular misalignment and provides flexibility in motion. This joint typically consists of a spherical inner ring with a bore that rotates within a cylindrical outer ring.

Threaded Shank: Rod end bearings come with a threaded shank that allows them to be easily mounted onto rods, shafts, or linkages. These threads can be male (external) or female (internal), providing versatility in connection options.

Material Composition: Rod end bearings are made from various materials to suit different application requirements. Common materials include stainless steel, carbon steel, and aluminum, often with surface treatments or coatings to enhance durability and resistance to corrosion.

Load Handling: These bearings are capable of managing both radial and axial loads, making them suitable for applications where directional loads are present. The design helps distribute the load evenly, ensuring efficient operation.

Maintenance Options: Rod end bearings are available in maintenance-free versions, which typically incorporate self-lubricating materials, and versions that require regular lubrication, allowing for choice based on maintenance capabilities and preferences.


Applications of Rod End Bearings:

Automotive: Used in suspension systems, steering linkages, and throttle linkages to provide precise control and smooth movement.

Aerospace: Employed in control systems, landing gear, and actuators where reliable and precise motion transfer is critical.

Industrial Machinery: Utilized in robotics, conveyors, and other machinery where flexible joint connections are needed.

Agricultural Equipment: Found in tractors, harvesters, and other equipment to facilitate movement and control of mechanical linkages.

Marine: Used in control systems and rigging where flexibility and load handling are essential.


Advantages of Rod End Bearings:

Versatility: Suitable for a wide range of applications due to their ability to handle angular misalignment and combined loads.

Ease of Installation: Threaded shanks allow for easy installation and adjustment, providing a secure connection.

Durability: Available in materials and designs that offer high durability and resistance to wear and corrosion, ensuring long service life.

Smooth Operation: The articulating joint design facilitates smooth and precise movement, enhancing the performance of mechanical systems.

Customization: Available in various sizes, thread types, and materials, allowing for customization to specific application requirements.


How to Use Rod End Bearings:

Select the Appropriate Bearing: Choose a rod end bearing based on the load requirements, environmental conditions, and desired maintenance level.

Install the Bearing: Thread the shank into the rod or linkage, ensuring it is securely fastened.

Align and Adjust: Adjust the position to achieve the desired alignment and secure with lock nuts or other fastening methods if necessary.

Maintenance: For maintenance-required versions, ensure regular lubrication as specified by the manufacturer to maintain optimal performance.


Rod end bearings are essential components in mechanical systems where precise movement and flexibility are required. Their ability to handle angular misalignment, combined loads, and varying environmental conditions makes them ideal for applications in automotive, aerospace, industrial machinery, agricultural equipment, and marine environments. By providing a robust and versatile connection, rod end bearings enhance the performance, reliability, and longevity of mechanical linkages and control systems.
