RE: Lubrication for Sliding Connection

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I would either epoxy bond a thin sheet of teflon to the bearing surface of
the tube or use a fabricated teflon bearing plate (such as Furon Fluorogold
bearing plates). If bearing pressures are low, use the bonded sheet; if
bearing pressures are high, use the fabricated bearing plates (higher cost).
