4. Unique Design Principle A) The shear restriction mechanism eliminates shear on “The DYMAT® Disc” element due to horizontal forces while allowing high vertical loading on the unique material. The result is a compact bearing.

5. Bearing is uncomplicated Rotation element is without critical tolerances compared to pots with sealing ring or curved mating sliding surface bearings. No greasing or PTFE lining is required to accommodate rotations.

6. Bearing design is low in overall height and is compact in plan size Final plan size based on connection details and displacement requirements.

9. Internal Up-lift Restraint Special bolts with Tyfo® alloy rotation elements provide up-lift restraint while allowing rotation at the same time. See page 11 for details.

10. Alternate connection details to all types of structures. (�����#���������*W

11. Basic bearings are standard production packages, special features are selected by designers from alternate anchorage details.

12. Special replaceability details for minimized jacking (�����#���������*W

13. Ease of inspection Rotation element visible from all sides.

14. Bearings are made of steel In the field of structural bearings, steel is a proven material. Special steels are available if specified. Fiber reinforced plate designs are available.

15. Unique Disc shape eliminates stress point “V” used in older designs.

16. Seismic and Base Isolation Designs available See page 14.

17. The Tyfo® element is an excellent dampening material for vibrations G=���3�����#���������� W +��Q���~G=��$��/G��$���W�
