ADVANTAGES

Maintenance-free service
Inexpensive, easy and fast to replace
Maximal uptime and reduction in maintenance cost
Suitable for higher loads
Allowing for enormous variability in shapes and sizes, solutions taking less space possible
Great emergency running properties
Performing particularly well in high-temperature environments up tp 650^oC
No moisture absorption, maximum dimensional accuracy and stability
Suitable for wide range of operating speeds

Ceramet self-lubricating plain bearings and bushings with a sintered sliding layer are especially suitable for continuous operations in a demanding environment. Sintering technology allows for the construction and manufacturing of a wide range of complex shapes with consistent self-lubricating properties throughout the whole lifecycle of critical moving parts. Sintered materials provide reliable and high-performance no-grease solutions.
