RE: Bridge slide bearings

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Aren’t there manufactured bearings of this kind that would be a better “fit” for this? In effect they’ve already done the “engineering” and you just have to make a selection?

Subject: Bridge slide bearings


I'm designing a walkway bridge slide bearing using a steel base plate bearing/sliding on a uhmwpe (ultra-high-molecular-weight polyethylene) sliding surface.  There is 3" of design movement.  Does anyone know what allowable bearing pressured should be used for the uhmwpe?  I have questions in to plastics manufacturers but I think they all have the holiday weeks off.
