New slewing bearings from igus use
two self-lubricating, low friction
polymer sliding elements in place of
conventional ball bearings. As a costeffective,
low noise alternative, the
PRT polymer slew ring bearing
modules are said to be highly wear
resistant, easy to install and
maintenance-free. They are robust
and have a high load capacity.

Housing parts are aluminium and
use stainless steel screws. Polymer
sliding pads are made of iglidur J
material, which contains a solid
lubricant, so it does not require
additional lubrication.
