Rectangular PTFE rubber support

Rectangular PTFE plate rubber bearings, also known as PTFE sliding plate bridge bearings, have the vertical stiffness and elastic deformation of ordinary plate rubber bearings, can accept straight loads and adapt to beam end rotation. Due to the low friction coefficient (μ ≤ 0.03) between PTFE and the stainless steel plate at the bottom of the beam, the horizontal displacement of the upper structure of the bridge is not constrained. Large span bridges, simply supported beam continuous slab bridges, and multi span continuous beam bridges with spans>30 meters can be used as movable bearings; Continuous beam pushing, T-shaped beam lateral movement, and large equipment sliding can be used as sliding blocks.
Tetrafluoroethylene sliding plate rubber bearings are made by sticking a layer of 1.5mm-3mm thick polytetrafluoroethylene plate on the surface of ordinary plate rubber bearings, also known as PTFE sliding plate bearings (GBZJH, GBZYH series). In addition to all the functions of GBZY series rubber bearings, the low friction coefficient between the polytetrafluoroethylene plate (F4 plate) and the stainless steel plate at the bottom of the beam enables the horizontal displacement of the upper structure to be unconstrained by the shear deformation of the bearings themselves, which can meet the large displacement needs of some bridges. This plate type rubber bearing not only has the function of a ball crown rubber bearing, but is also particularly suitable for bridges with large displacement. Widely used in factories, mines, machinery, electronics, mechanical equipment, kitchen equipment. The PTFE plate rubber bearing not only has advanced technology and functions, but also has the characteristics of simple structure, low price, no maintenance required, easy replacement of buffering and isolation, and a lower building height.
