igubal 2.0 – Metal-plastic rod ends are the new star in railway exteriors

Thorsten Mersch | 4. June 2020

In appointments with customers and during discussions at trade shows, our range of bearings with angle compensation is always well received. Lubrication-free and maintenance-free, in addition electrically insulating and vibration dampening. Ideal for solutions in the interior of trains such as seat adjustments.

For applications in outdoor areas, the subject of tensile strain and compressive load is often asked for. In the past, we always had to point out the limits of the polymer housing.

So far, anyway. Among the 100 new products that we presented in April, there is one innovation that is very special. With so many new products, an innovation can quickly get lost. But the new igubal rod end bearing quickly proved to be THE product for railway exteriors!

A 5 times higher breaking strength compared to the iglidur polymer material, but still maintenance-free and electrically insulating. The dream of every design engineer.

The iglidur polymer material KARM-12 has a permissible static tensile strain of 2,700N. The new metal-polymer solution KARM-12-MI-J-EK achieves a value of 15,949N here.

For brakes in bogies, pantographs on the roof and the adjustable front spoiler. Wherever adjustments are made by means of rods, the new rod ends can show their advantage. The absence of lubricants makes them the perfect solution for use where there is a high level of dust exposure from contact strips or brakes. Also ideal for pivot and slide doors, where a service life of 1 million cycles is often required.

New: KARM-12-MI-J-EK | galvanised steel housing, iglidur J ring, stainless steel spherical ball

Beginning in April with size 12, we received requests for sizes 8 – 20 after the presentation. All variations are available. Whether for materials such as galvanised steel or stainless steel for housing and spherical ball, female or male thread. Please ask for your required part. The modular concept leaves nothing to be desired.
