Sliding Isolator
 
A sliding isolator consists of a PTFE (Teflon) disc that slides
on a stainless steel plate. A slider may be manufactured with or
without an elastomeric backing. The most common slider has
the same construction as an isolator with a Teflon disc
substituted for the flange plate.
 
  Slider function
 
Sliders support vertical loads and have low lateral resistance. They are typically used in conjunction with isolators and enable the designer to optimize the performance of the isolation system. In some applications they are placed under lighter parts of the structure such as stairs and lightly loaded columns. The elastomeric backing is used to accommodate rotations in the structure. An added benefit of sliders is that they provide damping from sliding friction.
 
   
  Other Products
   
  Steelwork and fasteners
 
Dynamic Isolation Systems processes over 2000 tons of steel a year. Steel mounting plates, sole plates, anchor bolts and fasteners are often fabricated and supplied with DIS Isolators.
   
  Specialty Bearings
 
Dynamic Isolation Systems designs and builds bearings for non-seismic applications such as ship loaders. The purpose of the bearings is to control forces within the structure during the off-loading of oil from tankers.

Richmond San Rafael Bridge:
Dynamic Isolation Systems developed and fabricated bridge bearings for Caltrans with increased corrosion resistance. The bearings are located six feet above the waterline and were fabricated with low permeability rubber and stainless steel construction.
