A rod end bearing, also known as a heim joint (N. America) or rose joint (U.K. and elsewhere), is a mechanical articulating joint. Such joints are used on the ends of control rods, steering links, tie rods, or anywhere a precision articulating joint is required, and where a clevis end (which requires perfect 90-degree alignment between the attached shaft and the second component) is unsuitable. A ball swivel with an opening through which a bolt or other attaching hardware may pass is pressed into a circular casing with a threaded shaft attached. The threaded portion may be either male or female. The heim joint's advantage is that the ball insert permits the rod or bolt passing through it to be misaligned to a limited degree (an angle other than 90 degrees). A link terminated in two heim joints permits misalignment of their attached shafts (viz., other than 180 degrees).

The Commission has a huge opportunity to drive action to end this poisoning. Releasing the draft restriction to the REACH Committee now would leave a strong legacy for the current Commission and put us on a path towards meeting the zero-pollution ambition under the European Green Deal. It would also cement the EU as a leader in this space, alongside other countries and regions that are taking action, such as the USA.

The long awaited ban on the use of lead shots in wetlands finally came into force on 25 January. This sets the timetable for the ban’s implementation in Member States: they have until 15 February 2023, or 2024 if the country’s surface consists of more than 20% of wetlands.

With every delay, lead continues to disperse into the EU environment from hunting, sports shooting, and fishing. If this remains unmitigated, an estimated 44,000 tonnes of lead will continue to be released annually from these sources, polluting our environment, and causing extensive and unacceptable toxic impacts on people, domestic animals, and wildlife.

On the 28th of February, Birdlife and other fellow organisations sent a letter to Commissioner Thierry Breton and Commissioner Virginijus Sinkevičius urging them to present the draft restriction proposal without further delay. Non-toxic solutions that are safe for people, wildlife, and the environment are not only a possibility but already a reality. All we need, is to ban lead from hunting, sports shooting and fishing now.

The spherical rod end bearing was developed by Nazi Germany during World War II.[1] When one of the first German planes to be shot down by the British in early 1940 was examined, they found this joint in use in the aircraft's control systems. Following this discovery, the Allied governments gave the H.G. Heim Company an exclusive patent to manufacture these joints in North America, while in the UK the patent passed to Rose Bearings Ltd.[2] The ubiquity of these manufacturers in their respective markets led to the terms heim joint and rose joint becoming synonymous with their product. After the patents ran out the common names stuck, although as of 2017[update] rosejoint remains a registered trademark of Minebea Mitsumi Inc.,[3] successor to Rose Bearings Ltd. Originally used in aircraft, the rod end bearing may be found in cars, trucks, race cars,[4] motorcycles,[5] lawn tractors, boats, industrial machines, go-karts, radio-control helicopters, formula cars,[6] and many more applications.

Today, the EU REACH Committee1 held one of its regular meetings on how to protect human health and the environment from the potential risks associated with chemicals. Yet, there was one absentee from the discussion table, not only in today’s agenda, but also throughout the last year: lead poisoning from hunting, sports shooting, and fishing.

This week marks International Lead Poisoning Prevention Week – an initiative led by the World Health Organisation to raise awareness of the detrimental impacts of lead, particularly in children. Ironically, the week also coincides with a set of key meetings of the EU REACH committee – the panel that works on the EU chemicals regulation – where Member States are gathering to discuss how to tackle dangerous chemicals. But what’s not on the agenda? The restriction of lead in outdoor shooting and fishing.

Summer has ended, and Brussels is once again buzzing with activity. Following the European Parliament elections in June, both seasoned and new EU officials are settling into their roles. Over the next five years, the 720 Members of the European Parliament (MEPs), representing 27 EU countries, will make decisions that will directly affect the future of EU citizens. With the escalating climate and biodiversity crises demanding urgent attention, the direction Europe chooses now will determine not just the future of the Union, but also have significant implications for the very survival of our planet.

The European Commission delayed again the presentation of the draft amendments regarding a restriction on lead in outdoor shooting and fishing to Member States. It has been a year since the European Chemicals Agency (ECHA) sent their expert committee’s opinions and suggested restrictions to the European Commission. However, the Commission still hasn’t published its proposed amendment, nor justified this setback.

Using female heim joints will allow users to make precise changes on key components of fixtures. One example of needing fine adjustment is within the helicopter’s adjustment of the blades. When using the adjustment, it is key to make sure it is in the correct spot or excessive wear will occur. This change allows quick adjustments that are easy with a female heim joint. When dealing with the pitch of a helicopter blades, heim joints are able to be adjusted to 0.010in.[6] If spacing is critical, female heim joints are able to be threaded on, instead of welding inserts to the shaft. When dealing with aluminium shafts, the easiest way to use heim joints is to use the female heim joint. One example is using robots in robotics competitions. Light weight is a key factors when building competitive robots, so using aluminum rods and female heim joints can be key. [7] Another example using female heim joints is the shifter of motorcycles.[8] The shifting mechanism allows forces to be applied linear, but still be able to work at angles when in different gears. Both male and female heim joints require the use of a lock nut after getting adjustment to correct specification needed.
