Hydropower Bearing Bushing
INDRON®hybron bearing can be flexibly assembled into split bearing
with dovetail slat bearing bush, which is convenient for
installation and maintenance without shaft extension, and more
reliable when compared with the interference installation of
cylinder bearing. If necessary during overhaul, the slat bearing
bushes can be conveniently replaced, and a variety of homogeneous
elastoplastic polymer alloy dovetail slat bearing bushes of
different material grades can be mixed or staggered in one bearing,
so that the bearing achieves wear resistance and self-lubricating,
and effectively controls the balance of wobble.

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).
