- GLYCO® 190 works with soft mating surfaces under dry condition
- Excellent adaptability
- Ability of operation within the PTFE-overlay during all application service life
- Low friction
For some demanding damping applications running without any lubrication under oscillating conditions and soft mating surface, even solid plastic, maintenance free bearings do not achieve the targeted service life.
In addition friction improvement of the system efficiency is expected.
GLYCO® 190 is a three layer composite material. A porous tin bronze sinter structure is applied on a steel back. This layer is impregnated with a PTFE sliding material and a specific combination of fillers especially chosen to improve the performance of this material under dry running conditions. On the top of this filled bronze structure, a 50 to 100 μm thick overlay of the same sliding material is applied, providing a sufficient wear reserve for the operation of the damping application without even using the below bronze layer.
GLYCO® 190 sliding bearings are therefore providing in multiple vibration damping applications with high levels of requirements longer service life than usual PTFEbased materials. In addition, it offers lower friction than most thermoplastic-based materials, thus improving efficiency of the used system. Possible combination with other material through laser welded flange bushing.
