Selection criteria of FERROBAL ® rod ends and bearings
The specific application conditions and the installation settings of rod ends and bearings are varying in practical use and therefore cannot be
generalised in a catalogue.
The specific application conditions are
The installation setting is determined by:
affected by:
Factor and kind of affecting load:
• constant / alternating
• static / dynamic
• axial / radial
Angle of tilt
Swivelling angle
Temperature
Environment conditions
• dust
• dirt
• humidity
(This list may not be complete)
With the details given in the catalogue the user will be able to roughly determine the rod ends and bearings that will be adequate for the
concrete application.
Static load Co
The maximal admissible load of a FERROBAL ® rod end or bearing is specified by
the static load rating Co hat is indicated in the catalogue.
The static load rating Co of a plain bearing corresponds to the static radial load that does
not yet cause a lasting deformation at the weakest housing section of the rod end or bearing
during standstill at room temperature.
Temperature - range of application
Non-maintenance-free: -40°C to +300°C
(from +150°C with restriction of the loading capacity)
Maintenance free: -40°C to +130°C
In all cases the user has to coordinate the theoretical selection criteria with the
concrete installation situation and check the suitability of the rod end respectively
bearing. In this context the user has to define sufficient security factors and mainten
ance intervals.
Whenever the load is defined at the upper limit of the load rating
DURBAL Vertriebsgesellschaft is recommending to use
DURBAL ® heavy duty rod ends.
Our specialists will be pleased to provide advice.
Selection criteria
The maximal dimension of the machinery element.
The existing adapter sizes for threads or other connections.
The lubrication and maintenance situation.
Lubrication:
• wanted
• not wanted
• central lubrication
• decentralised lubrication
