For applications with only small twist angles, rubber-metal bushings are the first choice.

Slit bush – higher load due to preload
Quality is a question of the design principle. The slit bushing allows the highest possible preload of all bush types. It thus offers maximum load capacity with a small installation space.
Unlike conventional bushings, the slit bushing has a slitted outer tube. The slit continues in the rubber body and possibly in the intermediate plates and tapers to the inner tube.
With this principle, bushings with intermediate layers made of metal or plastic can be represented. This results in two or more rubber layers. Despite the intermediate layers, which are also slitted, all rubber layers are evenly tensioned. This leads to a large rubber height from the point of view of twisting synonymous with great twistability. At the same time, the bushing remains very rigid radially. Without intermediate layers, the large possible rotation angles could only be achieved with a radial stiffness of 10% and less that of a slit bushing.
New are such elastic joints, if they have a solid claw, in a lightweight version with up to 1/3 reduced weight! Thanks to a clever combination of primary materials, not only the weight but also the price decreases.
