Rod ends by KIPP
A rod end, sometimes called a spherical bearing or rod-end eye, is a mechanical operating part used to create a flexible connection between two parts. Rod ends enable movements around several axes and are often used in mechanical engineering applications. There they allow for movement, transmit forces and offer flexibility. Operating parts are also essential in industrial areas such as robotics, vehicle steering systems and material handling systems.
Due to their design, operating elements allow for precise motion transmission and are available in a variety of sizes and styles. Their versatility allows them to be used in a wide range of applications, from small hand-held devices to large industrial machines. Thanks to their precise control and positioning, rod ends are able to control movements accurately, which is crucial in many applications.

Operating principle of rod ends
A spherical bearing consists of a rod end housing and a spherical bearing that allows rotary movement around several axes. The exact operating principle may vary depending on the specific design and application, but in general, rod ends work as follows: The rod end consists of an outer housing which is often spherically shaped. The rod end housing also has one or more openings to accommodate the spherical bearing. It is designed so that it can be firmly connected to a part of the mechanical system while the spherical bearing is mounted inside it and allows movement.
A spherical bearing located inside the rod end housing and allows for the swivelling movement of the rod end around several axes. It can have different designs, such as ball bearings or plain bearings. The spherical bearing is often designed so that it can move freely around the axes while absorbing loads and forces affecting the rod end at the same time.
A thread or another fastening element connects the rod end to the mechanical system. This allows the rod end to move while being securely attached to the system.
Applications in industry
KIPP as the manufacturer offers rod ends so that they are supplied directly from manufacturing source ensuring improved control of product quality. Our rod ends are made from high-quality materials that guarantee high strength, wear resistance and durability. Such materials are carefully selected to ensure that our products perform reliably even under demanding conditions.
The versatility of these parts permit use in a wide range of applications. Application areas include the following industries:
- Automotive: In automotive production, operating parts are used in steering linkages, suspensions and other components to enable steering and suspension.
- Machine construction: Spherical bearings are used in various mechanical engineering applications, for example in robot arms, conveyor belts and connecting mechanisms.
- Aerospace technology: In aerospace technology, the heads are used in control mechanisms, flap mechanisms and landing gear to control and transmit movement.
- Heavy industry: Here, the parts are used in applications such as cranes, conveyor belts and lifting systems to move heavy loads.
- Agriculture: Rod ends are used in agricultural machinery and devices such as tractors, combine harvesters and trailers to allow movement and transmit forces.
- Medical technology: Spherical bearings can be found in surgical instruments, medical devices and prostheses.
- Electronics production: In electronics production, operating elements are used in automation systems and robots to carry out precise movements when assembling electronic components.
Types of rod ends
The KIPP product range includes 19 different types of operating parts in the "rod end" category. Besides spherical bearings, various rod ends with rod ends or ball bearings are available.
Products consist of the following materials:
- free-cutting steel
- stainless steel
- IGUMID
- steel
- QT steel
In addition to design and material, the products differ in mounting hole and thread size. The appropriate requirements can be selected using the filter function.
Rod ends with ball bearings
Rod ends with ball bearings are a very specific type of operating part. They enable low-friction and precise movement. The ball bearing allows for the rod end to rotate around different axes. The ball bearings ensure smooth and reliable movement. It ensures that the rod end can be moved freely and precisely without experiencing much friction.
The use of ball bearing mounted parts results in greater precision and better movement control compared to ends with other types of bearings. Therefore, the operating parts are particularly suitable for applications that require precise positioning and control.
As a manufacturer, KIPP sells two styles of ball bearing mounted spherical bearings. The main difference here is the type of thread.
- Rod end with ball bearing internal thread: The ball bearing of this operating part is long term greased with cover washers. The connection dimensions comply with DIN 648 form series KJ.
- Rod end with ball bearing external thread: The rod end with external thread is also a long term greased ball bearing with cover washers. The connection dimensions of this operating part comply with DIN 648 form series KA.
Rod ends with plain bearings
Rod ends with plain bearings are a variation in which the bearing is based on sliding elements. The sliding elements, which are often made of materials such as bronze, plastic or other lubricating materials, allow for low-friction movement of the rod end around various axes.
Compared to joints with ball bearings, the rod ends with plain bearings have a higher load rating. They are more suitable for applications involving high loads or extreme environmental conditions. By using sliding elements, rod ends can also provide improved vibration damping, making them particularly suitable for applications where vibration needs to be reduced.
Plain bearings generally require regular lubrication to ensure low-friction movement and minimise wear. However, this can be reduced by using self-lubricating materials that allow longer maintenance intervals.
Rod ends with plain bearing and internal thread
Rod ends with an internal thread have a thread inside the rod end. Due to the internal thread this allows for direct fastening to a corresponding external thread or screw. This makes installation much easier. The internal thread is available in different sizes and designs to meet the requirements of different applications.
The KIPP range includes seven different operating parts with plain bearings and internal thread:
According to DIN ISO 12240-1:
- Made of steel, maintenance free
- Made of stainless steel, maintenance free
- Made of steel, re-greaseable
- Narrow style, maintenance-free
According to DIN ISO 12240-4:
Rod ends with plain bearing and external thread
Rod ends with external thread have a thread on the outer surface of the rod end. It allows the rod end to be screwed into a corresponding nut, internal thread or other screw connection. The externally threaded parts offer a high degree of flexibility and adaptability, as they can simply be screwed onto existing screw connections or fastening elements.
The KIPP product range includes the following styles:
According to DIN ISO 12240-1:
- Made of steel, maintenance free
- Made of stainless steel, maintenance free
- Made of steel, re-greaseable
- Narrow style, maintenance-free
According to DIN ISO 12240-4:
Spherical bearings
The KIPP range includes two styles of spherical bearings. The bearing shell of both spherical bearings is made of stainless steel 1.4571, while the bearing ball is made of stainless steel 1.4034.
Stainless steel has a high strength and corrosion resistance. It is hygiene-friendly and temperature-resistant.
Spherical bearings by KIPP are excellent for use in case of dynamic loads under high pressure. A distinction is made between the styles according to the dimensional series.
Spherical bearings are available in dimensional series E and dimensional series K in different heights and with different fixing holes. Both dimensional series comply with DIN ISO 12240-1.
