DURBAL heavy-duty rod ends with integral self-aligning ball bearings, Series BRM,BRF,PM,PF
This design is especially suitable for high speeds, large swiveling angles or rotating movements with relatively low or medium loads. Prominent technical features are the low bearing friction, sealing against rough dirt penetration by means of shields on both sides. Under normal operating conditions the rod ends are maintenance-free. A Grease nipple is provided for lubrication during rough service and maximum loads. To avoid incompatibility with the initial lubrication, we recommend lubricating with a calcium-complexsoap- grease or Polyrex EP2. A special heat treatment procedure matches the rod end housing raceway hardness to the antifriction bearings, ensuring the same time high stability with changing loads.

DURBAL heavy-duty rod ends with a integral maintenance-free spherical plain bearing, Series BEM, BEF, EM, EF
In many cases DURBAL heavy-duty rod ends with integrated spherical plain bearing serve their purpose. They are primarly used for small swiveling or tilting movements at low speeds. They stand out for their high loadability and can also be used for shock loads.The ball slides on a composite bearing shell consisting of a glass fiber-filled nylon/teflon component. This design ensures an absolutely maintenance-free rod end. DURBAL heavy-duty plain bearing rod ends have a slight initial stress and virtually no clearance. The composite material used has a favorable secondary advantage in that it absorbs any foreign particles and embeds them so that no damage can occur. The joint balls of DURBAL heavy-duty rod ends with integrated spherical plain bearings are hard chrome plated. This reliable corrosion protection ensures that the function of the rod end will not be affected by a corroded ball surface under humid operating conditions.

DURBAL heavy-duty rod ends with integral self-aligning roller bearings, Series BRTM, BRTF
The design based on the structure of a self-aligning roller bearing is preferably used for high speed, large tilting angles or rotating motion with medium loads. Compared to rod ends with selfaligning ball bearings, rod ends with selfaligning roller bearings have essentially higher basic load ratings. This design is equipped with a cage to minimize the rolling friction and heat built-up. These rod ends are under normal operating conditions maintenance-free. A Grease nipple is provided for lubrication in case of rough operation and maximum load. To avoid incompatibility with the initial lubrication, we recommend lubricating with a calcium-complexsoap- grease or Polyrex EP2. Shields on both sides prevent dirt particles from penetrating into the bearing. The rod ends with selfaligning roller bearings are, just as the design with self-aligning ball bearings, subjected to a special heat treatment procedure to match the racway hardness to the antifriction bearings, ensuring at the same time a high stability with changing loads and temperature.

General description:
Let the industry leaders adapt or design a rod end to meet your unique requirements.
From a simple modification of an existing design to a completely unique concept, Alinabal engineers can give you the ideal configuration for your application.
Some of the options available include:
- Variations in shank or stud length
- Variations in ball bore dimensions
- Enhanced plating or corrosion resistance
- Metric dimensions
- Special materials such as stainless steel
- Sealed Rod Ends - In addition to the above, Alinabal has unmatched experience in the area of sealed rod ends. Using rubber or synthetic materials, Alinabal can design and produce rod ends fully protected from contaminants for greatly prolonged life in service.

NMB-Minebea is one of the leading manufacturers of rod-end and spherical bearings for the aerospace industry, as well as for industrial applications. The bearings are produced in the USA, Japan and other countries. In Europe, our subsidiary "NMB Minebea UK, Ltd." (based in Lincoln, England) develops and manufactures bearings for high-level applications. Using computer-supported CAD testing and production systems, our engineers not only develop standard bearings, but also extremely complex bearing systems in accordance with customer requirements.
Our products are used in high-level customer-specific applications, e.g. in civilian and military aircraft construction for wing flaps and landing gear. We possess all the required current international permits, approvals and licenses for this sector.
Furthermore, our rod-end bearings are used in high-speed trains and light rail transit, as well as in a broad range of other industrial projects.
Moreover, we also supply prominent Formula 1 racing teams and renowned vehicle manufacturers in the automotive industry, areas where the performance and reliability of our products have to be guaranteed at all times, even under extreme operating conditions.
In addition, we offer special fasteners for the aerospace industry.
