GLYCO® 393
Key Features
- Advanced machinable dry bearing material for high loads and precision requirements
- Thermoplastic based material for high load capacity and wear resistance under lubricated and non lubricated conditions.
- High PTFE content for significant friction reduction and for allowing use in unlubricated applications
- Best in class material in performance and enabling of multiple application cases (dry, greased, oiled, machining after assembly).
A high number of fluid lubricated applications need to be fit with self lubricating composite material bushings due to mixed friction conditions.
Increasing precision requirements (reduced misalignment or shaft clearance) needs to be achieved.
Increased specific loads are placed on the bearings.
GLYCO® 393 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.
Surface roughness of Rz = 4 – 6 µm achievable through machining of the top layer with the proper process parameter (3000 – 5000 rpm, feed rate of 0,02 mm/rpm) and optimized tool.
