- Usable under severely loaded fluid lubricated or greased conditions
- High pv-value
- Very high wear resistance
- Very high load capacity
- High thermal strength
- Rotating, oscillating and axial motion possible
Some particular greased or fluid lubricated applications need to be able to endure for long periods very high loads at elevated temperatures.
These operating conditions are reducing significantly the service life when standard materials are used, inducing a risk of material seizure before the application end of life.
GLYCO® 95 is a three layer composite material. A porous tin bronze sinter structure is applied on a steel back, which is impregnated with a PEEK 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 2.5 m/s under greased operation. In oil lubricated applications, higher values up to 10 m/s or more depending on lubricant supply conditions are possible.
