HOW THE SURROUNDINGS INFLUENCE PLANE BEARINGS<br />
Polymer plane bearings made of specially modified<br />
compounds for the best operating results in maintenancepoor<br />
or maintenance-free surroundings. Through many years<br />
of experiences we have continuously improved our materials.<br />
Today, we are able to cover a large segment of applications<br />
with our products.<br />
Many factors have an influence on the successful operation<br />
of plane bearings. Temperature is a determining factor.<br />
Polymers change their properties more radically at different<br />
temperatures than conventional metal-polymer bearings.<br />
Approximate values and orientation cannot replace a test<br />
under real everyday conditions of a system. Check operational<br />
temperature, loads, life, safety and the insertion tolerance<br />
and lubrication edge pressures or unwanted inclusion of dirt<br />
particles.<br />
