Notes on lubrication
CTU features rails with self-lubricating recirculating ball bear-
ings.
Carriages with recirculating ball bearings also have a retain-
ing cage that eliminates the “steel on steel” contact between
adjacent rolling bodies and prevents misalignments of theses
parts in the circuits.
Lubricant tanks are installed on the fronts of carriages with
recirculating ball bearings. These small reservoirs release the
right quantity of lubricant in the areas where the ball bearings
support the applied loads.
This system guarantees long maintenance intervals: every
5000 km or once a year, whichever quantity is reached first.
■
Insert the dispensing nozzle into the specific lubricator.
■
Type of lubricant: class NLGI 2 lithium soap based grease.
■
More frequent lubrication is necessary for heavy duty
applications or difficult environmental conditions.
For more information, contact Rollon.
