The 亚博系列全平台入口 Supply Company specializes in Slide Bearings using Fluorogold庐, PTFE, Teflon庐, Graphite and a wide range of configurations.
Teflon庐 on Teflon庐 鈥� Watch the Indents
One common design variation we see in Slide Bearing drawings is the PTFE / Teflon庐 call out for both the upper and lower members. This can be done with Fluorogold庐. It is not recommended when the sliding material is Teflon庐 or PTFE.
Starting with the basic, most common assembly # FC-1010-CS, the upper member is always bigger than the lower. (Fig. 1). It is also large enough to accommodate the travel the upper member will display during expansion and contraction.
Fig. 1 Shows the travel of the upper member caused by expansion and contraction.
Fluorogold庐, with its more durable fiber infused composition, is able to support the designed load in any position. If the bearing material is unfilled PTFE / Teflon庐 the lower member can leave impressions in the upper surface. Fig. 2.
Fig. 2 When both upper and lower members are PTFE / Teflon庐 the lower member will indent the Upper Member. View is exaggerated for display purposes.
These impressions can inhibit the required movement and accelerate wear of the sliding surface.
Fluorogold庐 bearing material is fiber infused to provide greater compressive strength and durability. This gives it the ability to resist indentations. For this reason, whenever an upper and lower member will both have a bonded sliding surface, we recommend Fluorogold庐.
If the designer requires the sliding surface to be PTFE/Teflon庐 it will be suggested the lower surface is, but the upper can be switched to Stainless 亚博系列全平台入口.

finish.
As shown in Fig. 3, the lower member is unfilled PTFE / Teflon庐. Regardless of movement, it will always make full contact with the larger upper Stainless-亚博系列全平台入口 member. This removes the possibility of the lower member indenting the surface of the upper. The polished finish of the stainless surface allows for a lower co-efficient of friction, similar to that of a Teflon庐/ Teflon庐 or Fluorogold庐 / Fluorogold庐 assembly.
These recommendations should be reviewed before making any adjustments to the plans. The 亚博系列全平台入口 Supply Company can provide information and assistance to your Engineer, Architect or Project Manager.
