Getzner bearings for floating floors guarantee a more peaceful atmosphere in the train interior. “Our high-tech elastomers are highly effective despite their low overall height, and can therefore be relied upon to meet the required noise levels in the passenger carriages”, explains Tomoko Takekawa. “The elastomers minimise the transfer of vibrations to the interior fittings, the structure and the electronic components. Not only does this significantly reduce noise, but also wear. In summary, elastic bearings lower maintenance costs.” This is a key sales argument for manufacturers of rail vehicles and rail operators.

The fact that the polyurethane materials Sylomer® and Sylodyn® from Getzner are among the leading vibration isolation materials on the international market is not only reflected in their effectiveness in reducing vibrations and noise. The elastic bearings in the floating floors of the new Hitachi trains are made of the fire retardant material Sylomer® FR. This achieves a Hazard Level (HL) 3 rating for floor constructions (R10) and meets the European requirements of the DIN EN 45545-2 ire protection standard for rail vehicles. Tests and classifications according to German DIN 5510-2, American NFPA 130 and Japanese JRMA are also available.
