Slide bearings is a special formulation PTFE, reinforced with a glass fiber aggregate to provide a structural material that offers significant compressive strength without cold, flow, yet retains the low-friction (.06) and chemically inert characteristics of unfilled PTFE.

Fluorogold composition, manufactured into sheets of required thickness, is factory bonded, using precise heat and pressure in hydraulic presses, to specially prepared backing plates or supporting materials such as carbon steel, stainless steel, bridge-bearing neoprene, fabric reinforced rubber pads or other required composition. The resulting combination is cut to required size as simple "slide bearings" or fabricated into bearing assemblies in combination with anchorage devices, special hardware and elastomeric materials.

Through much of my research on homemade CNC machines, I found that the mechanism to provide linear sliding is simply the use of an angle ("L" shaped piece of metal), bolts or screws (5/16" at 3/4" in length), nuts (5/16") and standard skate bearings (I use ABEC7/608Z). The design is actually very efficient and clutter free. When I say clutter free, I mean that the exhaust of sawdust that the CNC will produce will not clog up these bearings. Collar bearings, or bushing bearings I believe will have the tendency to receive material within the bearing housing creating a binding effect. If you are wondering what a bearing bushing is, imagine a cylindrical tube with little balls housed on the inside surface of the tube. The skate bearing method is like creating a new kind of hybrid inline skates and those skates you used in the 80's with the four wheels

Fabreeka structural expansion bearings, or slide bearings, accommodate thermal expansion and structural rotation in buildings, bridges and pipe supports. Fabreeka designs and manufactures four types of expansion / slide bearings for a wide range of applications. The expansion bearings are supplied as an upper and lower unit prepared to be tack or stitch welded in the field.
