GLYCO® 97

Key Features

  • Maintenance-free operation lubrication for use under severe dry running conditions
  • High pv-value
  • Good wear resistance
  • High load capacity
  • Low friction
  • Rotating, oscillating and axial motion possible
  • Wide range of part design types

For some applications operated without any lubrication, maintenance free bearings do not achieve the targeted service life. Performances in friction improving the system efficiency are also below expectations.

Reasons could be the use of standard performance PTFE-materials, not optimized for dry running conditions at higher loads and long operation periods.

GLYCO® 97 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 5 to 30 μm thick overlay of the same sliding material is applied, providing the initial lubrication during the running-in of the application. 

GLYCO® 97 sliding bearings are therefore showing lower friction and in the same time higher wear resistance under dry operation compared to other standard PTFE-based materials. In addition, it is available on request with a thinner top layer offering advantages for applications involving a cataphoretic painting process.
