Free of oil of less oil lubrication, applicable for conditions such as incapable of adding or difficult to add oil. it can be used without maintenance or less maintenance.
With good wearing quality,small friction factor and long performance life.
With certain elasto-plasticity,which can distribute the stress to a wider contact surface,thus the load capacity is promoted.
Static and kinetic friction coefficient is very near, which can make the bearing crawl at low speed, so as to guarantee the operation precision ofprecision machinery.
Good running-in feature,need no scraping upon assembling. It can reduce vibration of the mechanism so that noise is depressed, which preventsenvironmental pollution and improves working condition.
Shifting membrane is formed during the course of running, which can protect the counter-friction shaft from wearing and seizing.
Low requirement of hardness for the counter-friction shaft.Even you can use ones without quenching and tempering. so that processing difficulty lowers down.
It is of thin-wall structure and light weight. which can reduce the size of the mechanism.
On water or oil absorption, low thermal coefficient, good thermal diffusivity and stable dimensions.
The base plate can adopt stainless steel,the blue and green copper,such materials as the stencil plate of low carbon,etc. . Need with right various kinds of working environment.
