Today I talked with a material engineer here at work, showed him the clamini bushings, explained him the job they do and some videos to make clear what we need in a bushing for our CSS.

After that, he said we can try NYLAMID. That is the trademark for a material made of some polimers like nylon, acetal and polietilen. Also, it comes with self lubricated options, it is loaded with bisulfur of molybdenum. It is machined with the same equipment to machine bronze pieces. It is used in some bushings and high stressed components of our heavy machines (Germany made) here in our plant.

Nylamid ( only english search ) seems to be the mexican brand of the material, because I couldnt find good english info about it. Should be a equivalent USA brand for this material.

Well, what I could find about Nylamid is this:

Some of the caracteristics of Nylamid:

Dimenisonal stability
Malleability
Wear resistance
dielectric resistance
mechanic resistance
chemical resistance
Thermic resistance
Rigidity

Nylamid SL (super lubricated) specs:

Density 1.16 gr./cm3
hardness (Shore-D) 85
Tension resistance 878 kg./cm2
Compression resistance 1,124 kg./cm2
flexion resistance 1,195 kg./cm2
Impact resistance 2.72 kg./cm2

Maybe someone with the proper knowledge can take a look at this specs and bring more light regarding the possible use of this material in our bushings.
