GLYCO® 193

Key Features

  • Usable under severe fluid lubricated or greased conditions
  • Running as well as under dry conditions due to the PTFE additive
  • High pv-value
  • Very high wear resistance
  • Very high load capacity
  • Low friction (improved through PTFE)
  • High thermal strength
  • Rotating, oscillating and axial motion possible

Some particular fluid lubricated applications need to be able to endure very high loads under poor lubrication supply, thus operating for long periods under mixed friction conditions at higher wear rate and elevated temperatures. 

Other special applications are running greased or even without any lubrication under high axial or radial pressures reducing considerably the service life when standard materials are used.

GLYCO® 193 is a three layer composite material. A porous tin bronze sinter structure is applied on a steel back, which is impregnated with a PPS sliding material with friction improving and wear reducing additives. An overlay of the same sliding material is located above the filled bronze structure.

Maximum sliding velocity of 2 m/s under dry operation. 

In a lubricated application, higher values up to 10 m/s or more depending on lubricant supply conditions are possible.
