ADVANTAGES

Maintenance-free service
Inexpensive, easy, and fast to replace
Suitable for intermittent movements
Allowing for enormous variability in shapes and sizes
High load endurance that offers high wear resistance
Clean working environment
Removing fire hazard by eliminating of grease
High number of cycles due to special self-lubricating sliding surface resulting in low wear rate
Tight tolerance and low wear to guarantee precise closing of the machine
Optional lubricating pockets for grease and oil lubrication are available

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.
