For operating temperatures exceeding Series
100 & 200 grades, use Series 300 to 400° F
(204°C) with a compressive strength of 35,000
PSI (241 MPA). Series 300 is available with the
same solid lubricants as the standard grades.
As is common with all resin bonded fabrics
CIP has a low thermal conductivity. Under
normal circumstances frictional heat is removed
via the mating metal surface. However, in cases
where shafts or housings are conducting heat to
the bearing assembly, the lubricant must be sufficient
to remove both frictional and conducted heat.
The removal of frictional heat may be improved
particularly in dry running applications,
by using the housing as the main heat conductor.
The wall thickness of bearings should be
kept to a minimum in order to improve heat
dissipation.
Thermal expansion of CIP material is greater
than that of most metal alloy bearings and the
characteristic must be taken into account in
designs for higher temperature applications.
For applications where there will be a temperature
change of > 60° F (15°C), please consult
with Columbia Industrial Products for correct
running clearance.
