About GTW – Gleitlagertechnik Weißbacher
Gleitlagertechnik Weißbacher GmbH (GTW) has been designing, manufacturing and repairing oil-lubricated plain bearings for general mechanical engineering for more than 35 years. The basic body of the plain bearings is usually made of steel, in individual cases of copper alloys. A layer of tin-based white metal or a polymer based on polyetheretherketone (PEEK) is applied to it, enabling the machine to start up from standstill without damage to the shaft. During operation there is no contact between shaft and bearing, so the plain bearing operates in continuous duty essentially without wear. Fields of application include power generation and conversion (generators from 1 to 1400 MW, gas and steam turbines from 0.1 to 1000 MW, water turbines, gearboxes up to 90 MW, large motors from 1 to 100 MW), shipbuilding with bearings for diesel generators and electric ship propulsion, grinding technology with journal bearings and slide shoe bearings for roller and tube mill gearboxes, as well as special applications such as plain bearing arrangements for turbocompressors. Based on a specification document, GTW develops complete problem solutions covering development, design, procurement and manufacturing, and additionally offers conversion and modernization of existing systems as well as a repair service.
