Press forming - Import export

These bearings consist of a cage made from a steel plate, which is precisely press formed and surfacehardened, and needle rollers with a diameter variation within 2μm. They have a rigid structure and a high lubricantretaining capacity. As they have the lowest sectional height compared with other thrust bearings, they can be used instead of conventional thrust washers and can withstand highspeed rotations with a low coefficient of friction.

Proper bending of aluminium and magnesium requires specific knowledge of the material. The phase in the process in which the material is bent is also crucial to the final result, right after pressing or only after hardening, for example. There are many techniques for bending, such as roll forming, press (brake) bending, swivel bending, deep drawing, stretch forming, and 3D bending.
