Hi, I´m working on a product that will include a sliding seat which needs to carry the weight of an adult person, say 120 kgs with some margin. It does not need to be very exact/distinct in it´s operation, but needs to be affordable and therefore made from existing parts such as rail and rollers/bearings. As silent as possible but can´t be too picky. I came across Openrail linear rail that attached to our product and combined with v-shaped rollers looks interesting, however I suspect that it will eventually be too weak for our application. Does anyone have any suggestions on other systems/available products to look at? Many thanks in advance /Svante
