    Certification for ROPS under OSHA 1928.53

    Yes, the structure will move under the 705 lbs, indeed it moved almost exactly an inch (this is real world, not some hypothetical situation). What I am trying to get my head around is the unit of measure. Ft-Lbs. 58.75 in this instance. If the same force (705 lbs) is applied, and the...

    Oil Filled Nylon

    Thank you guys, thank you Pat, As with most things, the more I learn, the more I realize how much I don't know. No lubricity inherent with the MoS2 eh? Never would have thought that. What we are looking for is the most slippery material we can find, while still retaining good mechanical...

    Oil Filled Nylon

    Thank you Ornery. We will not see any high temps. My experience with oilite bronze bearings are that they do indeed "seep". That is my concern with the nylon as well, as the (oilite) seepage attracts and hold contaminants. Anyone else have any experience? Jonny

    Oil Filled Nylon

    I am considering using an oil and MoS2 filled nylon (such as Nylatron GSM Blue) for a sliding "puck" in a variable pulley system. This part will need to slide agains some aluminum ramps to actuate the gizmo. My concerns are that the oil in the nylon will attract contaminants, as the...
