GLYCO® 290

Key Features

  • Thermoplastic for high load capacity and wear resistance combined with PTFE for low friction reduction, flexibility and use in unlubricated applications.
  • Clearance-free installation due to high degree of flexibility enables reaching defined torque range together with press-fit.
  • Very small installation space (0.5 mm wall)
  • Cost efficient compared to conventional materials with porous bronze.
  • Optionally high corrosion resistance with G-290 in case of stainless steel structure.

Provide a solution for dry applications with minimum installation space but requiring also high load capacity and wear resistance, like door hinges and seat mechanisms.

Despite the thin wall and the necessary flexibility for a flange bushing production and a zero-clearance assembly, the material shall provide enough rigidity to ensure a sufficient press fit of the bushing inside the housing.

GLYCO® 290 is based on a steel-expanded metal impregnated and covered with a highly loadable polymer compound based on PTFE and thermoplastic materials giving  improved wear and friction properties under dry running conditions. On the back of the material the expanded metal is partially exposed.

Only 0.5 mm thick, G-290 provides a premium solution for applications where conventional rigid bushings (above 0.7 mm) are too thick and mesh-based thin bushings are too flexible to allow press-fitting and automated assembly.
