INDRON® bearings with metal-based coating are an ideal alternative to oil -
lubricated metal bearings for guide vanes, whose creative coating
design has overcome the restriction of dry - ice installation for
polymer bearings and eliminated the obvious clearance changes
caused by the water swelling of polymer and thermal expansion.
- Best fit clearances are maintained thanks to tiny water swelling
and dimensional changes.
- Maximum load capacity (25% strain) up to 100Mpa.
- Effective protection of the shaft neck and reliable performances
due to full coverage of the shaft neck.
- Avoids the inconvenience that a typical polymer bearing has to be
refrigerated by dry ice during installation.

Note:
There are three grades of dovetail slat bearing bush materials to
choose from. White TSTN is selected by default for water pumps. In
addition, the materials are marked with TQDS40/xxxx (the last four
characters represent materials). Tolerance is controlled under the
conditions of ambient temperature of 21-28ºC and relative humidity of 40-60% when the slats leave the factory.
Beyond the environmental condition, the slat size may be affected
by environmental conditions and exceed the tolerance range. In such
case, please submit the conditions of measurement environment and
slat size, and contact the manufacturer to confirm whether it is
reasonable and available. (The maximum length of a slat is 830mm,
which can be customized on demand).
