Reinforced Elastomeric Bearings

Type B (1) – reinforced bearing, fully covered with elastomer and comprising at least two steel reinforcing sheets. The permanent load has to be sufficient for slip prevention.

Type B/C (1/2) – reinforced bearing with one outer steel plate on one surface. The steel plate allows to use almost any means against slip protection like dowels, threaded

rods, bolts etc. The single sided slip protection allows an easy bearing installation and exchange. Slip protection is necessary in case of a pressure less than the minimum pressure of the bearing. Type B/C can be installed if the construction is secured in its position e.g. by a bearing that is fixed in all directions or transversely fixed.

Type C (2) – reinforced bearing, both bearing surfaces are formed of steel plates to allow a slip protection. Bearing exchanges of this type are difficult to conduct without additional measures. As a floating bearing, this bearing type can depend on the stiffness and transfer of horizontal loads (breaking etc.). An example type C (2) bearing exchange is shown below.

Type C (5) – reinforced bearing, both bearing surfaces are slip protected by profiled steel plates (e.g. checker plates, non slip steel plates).

Due to the fact that the required load can not be defined exactly, it should only be used for structures with minor loads or for building constructions. Because of the profiled surfaces it can not be employed between restraining structures.
