Four-row Linear Guide System (with full complement) on a steel profiled rail.
The individual Linear Guide System carriages can be loaded from all directions
and can absorb moments around all axes. The key features of Linear Guide Sys-
tem PS 4-15 are its high carrying capacity, rigidity and compact design. Each
Linear Guide System carriage can be freely combined with every Linear Guide
System rail, so that one or more carriages are possible per rail and carriages
can be exchanged.
The Linear Guide System is pre-loaded when it leaves the factory.
Application
The carriages must be used in combination in order to absorb high forces and
moments.
Solutions involving several carriages on a single rail and several carriages on
parallel rails are also possible.
Guide systems with parallel rails on a single support profile can be constructed
on profile groove 8 without elaborate alignment due to the special fastening
geometry employed by the rail. The use of parallel rails on different support
constructions (i.e. steel frames) will require the amount of alignment and
fastening typical for profile rail guides (machining of mounting surfaces, use of
accurate spacing pieces etc.)
Technical Data
Note: The static and dynamic load factors and the static moment characterize
the rolling-ball contact between the carriage and rail and can be used for
calculating the service life.
For every application, it is necessary to check whether the 4 mm rail mounting
screws will support the anticipated load. For some of the permissible loads (in
particular M0x), the fastening strength lies below the load carrying capacity of
the rolling-ball contact.
The load factors are identical for loads in all axes. The static load safety
factor S
0
= C
0
/ P greater than 4 should always be selected.
The dynamic load factor C is based on a nominal service life of 100,000 m
travel i.e. 90% of a large sample of identical bearings achieve this performance
level without any sign of material fatigue.
In each individual case, however, it is important to check the link to the
connecting structures in order to verify that it is able to support the
forces and moments applied to the Linear Guide System!
