MAURER Structural Bearings Vibrations, rotations and powerful forces – bridges and superstructures may undergo a turbulent life. MAURER Structural Bearings ensure at any place that these impacts remain as long as possible without consequences. In order to guarantee the quality and longevity of our products, we strive for highest precision, continuous monitoring and close cooperation with the official material testing institutes during the production process. Bearings transmit vertical and horizontal loads from the superstructure into the bottom structure allowing for rotations and relative...

>> MAURER MSM® / MSA® Spherical Bearings For nearly 50 years, MAURER has been the market leader in design and production of spherical bearings. Resembling the construction principle of a hinge, spherical bearings enable reaching the smallest possible footprint and very high rotations with low resistance. A spherical calotte which rotates with low friction on an MSM® layer allows for rotations around the main axes. The displacements are achieved by a second MSM® layer sliding on a stainless steel or coated mating surface, while lateral forces are transmitted by suitable guides. To achieve...

>> Key characteristics of MAURER Spherical Bearings ✓ Lowest friction (low rotational and sliding resistance) solution ✓ Idealservice lifein terms of sliding properties, bearing surface and Ageing-resistant thanks to the use of MSM®, corrosion-free ✓ MSA® and structural steel Adjustment of rotations and extreme vertical and horizontal ✓ loads without gapping ✓ Smallest possible footprint a temperature ✓ Suitable forregion to desertrange from -50 °C to +70 °C from polar climate ✓ According to ETA-06/0131, EN 1337 or AASHTO ✓ Service life of 50 years plus ✓ Working in harsh atmospheric...

MSM® stands for MAURER Sliding Material. The name is a registered brand. MSM® is a patented, high-performance sliding material for structural bearings. An ultra high molecular polyethylene modified with various additives, featuring enhanced sliding characteristics. In comparison to usual PTFE, MSM® is characterised by substantially higher durability, twice as high allowable pressure and therefore smaller dimensions as well as lower sliding resistance. MSM® does not contain regenerated or filling material or any environmentally hazardous components, like fluorine or chlorine. MSM® is...

The structural rotations are adjusted thanks to an elastomeric pad, which responds with high vertical stiffness and low rotation resistance, confined into a steel pot. The displacements are adjusted by a PTFE layer sliding on a stainless steel sheet. For guided or fixed bearings, external lateral forces are transmitted by suitable restraints or guides. The durability of the internal seal is a crucial point. Our patented PTFE/carbon internal seal has been tested for 2 km accumulated rotations without wear. >> ey characteristics K of MAURER Pot Bearings solution ✓ Cost-effective small for...

>> MAURER Elastomeric Bearings >> Key characteristics of MAURER Elastomeric Bearings ✓ Cost-effective solution for minor loads, movements MAURER Elastomeric Bearing MAURER Elastomeric Bearings are available in natural or chloroprene rubber with steel reinforcement plates. Depending on their type, they can also transmit external forces by means of guides or restraints. The regular shear modulus (Gg) of elastomeric bearings is 0.9 MPa. On request, we supply bearings with other shear moduli and according to requirements of the project or other standards, e.g. AASHTO. When the rubber pad...

>> MAURER Special Bearings MAURER also delivers structural bearings for special applications and extraordinary areas of use. The solutions we offer are individual and highly efficient, exceeding by far the common types of structural bearings. >> MAURER UPLIFT SPHERICAL BEARINGS MAURER Uplift Spherical Bearings enable the transfer and support of vertical compressive and tractive forces without slack and in combination with any rotation and displacement. The uplift forces can also occur with the combination of rotation in SLS case. MAURER Uplift Spherical Bearings are particularly suitable...

>> MAURER ROLLER BEARINGS Roller bearings are only used in exceptional cases, e.g. maintenance work, since they can only rotate around one axis. MAURER Roller Bearings are available in structural steel with CE marking according to EN 1337-4 or in a compact design with an overlay-welded outer surface according to the General Technical Approval of DIBt (Deutsches Institut für Bautechnik). MAURER Roller Bearings >> MAURER BEARINGS WITH LOAD MEASUREMENT In order to survey load modifications, our bearings can be equipped with sensors to continuously monitor the load.
