About GLT Essen
Gleitlagertechnik Essen GmbH (GLT) specializes in the development, manufacture, assembly and regeneration of plain bearings. The portfolio includes tilting-pad and fixed-profile bearings with diameters from 50 mm to over 4,000 mm, new manufacture for original equipment and spare parts, housing manufacture, assemblies, accessories and special bronze in centrifugal casting up to Ø 3,000 mm. Core competencies are white metal coating by centrifugal casting, static casting and bearing metal welding, as well as complete regeneration of existing bearing shells with reuse of the old backing shells. In addition, GLT offers engineering and bearing design, damage analysis, non-destructive testing, build-to-print component manufacture and application training. Customers come from hydropower, gearbox manufacturing, the cement industry, marine propulsion, rolling mill technology, turbomachinery and power plant engineering; more than 50 employees manufacture at one plant in Essen.

Bearing Materials & Coating Processes
White Metal (Babbitt Metal)
High-lead and high-tin alloys as a running surface, typically cast in a thin layer onto a steel backing shell.
Special Bronze
For special applications such as rotary valves and vertical mills, available in centrifugal casting up to Ø 3,000 mm.
Bronze with Embedded Graphite
Bronze bearings for demanding, heavily contaminated environments with high load capacity and impact resistance.
Brass
Proven plain bearing material for medium loads and moderate temperatures.
Steel
Backing shells and backing bodies made of steel for the composite with bearing metal.
Polymers
Material for plain bearings with special application requirements.
Ceramics
Material for plain bearings with special application requirements.
Centrifugal Casting
Bearing metal is cast into the rotating backing body; centrifugal force ensures excellent bond strength and low porosity.
Static Casting
Manual casting of liquid bearing metal, e.g. onto thrust pads using a casting frame.
Bearing Metal Welding
Coating with bearing metal profiles (triangular/square) for base bodies of practically any size and geometry.
