Design Features
Design Features:
- The thickness and number of elastomer layers influence its vertical stiffness and its load carrying capability
- The overall thickness displacement is mainly determined by the bearing's overall elastomer thickness
- High-performance and specially formulated outer layers can be provided to give the bearing better resistance to environmental attack (Ozone UV etc.)
- The quantity and geometry of the plates will determine the load bearing and stiffness characteristics
Other Features:
- Special sizes to suit any application
- Natural elastomer is the standard material but Polychloroprene and SBR are also available
- Top and bottom mounting plates are available
- Holes for locating pins are supplied where specified
- Bearings with specification beyond what is shown can also be designed. Please contact us for further details
