Fiber-reinforced graphite composite has a much lower coefficient of friction compared to water-lubricated steel (0,15) than textolite (0,3).
Properties of graphitamide rolling mill bearings
Grafitamide has mechanical strength and impact strength higher than textolite, the ability to self-ruin, dampen vibrations and capture abrasive particles, is self-lubricating, resistant to water, oil, gasoline and chemicals.
The high abrasion resistance of graphitamide is achieved thanks to the reinforcement with graphite-lubricated fibers, which create a three-dimensional sliding structure that protects the matrix resin.
Service life of graphitamide rolling mill shells
The twice-shorter service life of textolite compared to graphitamide is primarily due to the higher friction coefficient of textolite in an aqueous environment, which causes:
- accelerated abrasion of the acetabulum
- work at higher temperatures damaging the cotton carrier in the textolite
- weakening of mechanical strength due to the action of water and oil, which leads to uneven wear, delamination and cracks.
In the case of graphitamide, increased temperature, water and oil improve its properties, especially impact strength. Water works very well with graphite, reducing friction and wear.
Savings when using graphitamide bearings
The savings resulting from the use of new generation bearings are easy to calculate for those who are forced to make production breaks and labor-intensive replacement of damaged textolite bearings every month.
