MAURER MSM®-Guide Bearings New General Approval Minimum life time of 50 years Maintenance free Suitable for all climate zones worldwide from -50°C to +70°C Reduced strains onto the adjacent structure Section through a MAURER Guide Bearing with special sliding material MSM® (orange) As a first manufacturer, Maurer Söhne has gained a Natinal General Approval for Guide Bearings with special sliding material. The General Approval Z-16.9-463 for MAURER MSM®-Guide Bearings permits a more comprehensive use of the well proven sliding material MSM® (MAURER Sliding Material). mode, as well as a special suitability for soft structures with fast and frequent movements, like they occur in railway bridges Like in the guides of such spherical bearings, now all design types of guide bearings can be equipped with MSM® strips, which allows using the many advantages of MSM®. These are, among others: The approval concerns guide bearings according to EN1337-8, with the sliding material in the guides being replaced by the special sliding material MSM®. This modification is of deciding importance for the life time, the economics and the scope of usage of guide bearings. With obtaining the National Approval, once more Maurer Söhne displays its role as pioneer in the field of bridge bearings. The introduction of the sliding material MSM® was a revolution in the field of bridge bearings. In 2003, MAURER MSM®-Spherical Bearings were approved nationally, and 2006 on a European scale This type of bearing displays a high life time, small resistance to displacement, a compact and economic design Whereas the assumed life time of PTFE respectively the composite material CM1 in guides is 10 years, with the usage of MSM® the same is augmented to 50 years. And this absolutely maintenance free. Furthermore, the new approval contains a calculation mode for the determination of the life time. Thus, it is now possible to make statements for the budget planning of the structure. Exact forecasts, when and whether the guide bearings have to be replaced, are now possible.

MAURER MSM®-Guide Bearings New General Approval The 5 fold life time of the MSM® material permits longer inspection intervals and avoids a cost intensive replacement of bearings, and this often applying to the complete life time of the bridge structure. . By way of its double permissible compressive strength, MAURER MSM® guide bearings can be designed in a very compact mode and also rather flat. The compressive strength of MSM® lies approximately on the level of CM1 which is ruled in EN1337-2 Due to its incompressibility, CM1 reacts very sensibly to edge pressures, and so no rotations can...
