Rod Lock
Series RL
For cylinders ISO 6431/VDMA and ISO 6432
ø 20 - 25 - 32 - 40 - 50 - 63 - 80 - 100 - 125
The Series RL rod locks are available
in 9 different sizes (diameters: 20, 25,
32, 40, 50, 63, 80, 100
to 125 mm).
The compact dimensions allow units to
be fitted on cylinders where space is
limited.
Rod lock units are often used to hold
the load in position during Emergency
Stop conditions or when the air supply
may be accidently disconnected from
the system. The holding forces are
measured at 8 bar and apply in both
directions.
Caution!
The rod lock should not be used to
“
brake” the piston rod in dynamic
conditions and must only be applied
when movement has ceased.
Note:
the cylinder piston rod length must be
increased when using a rod lock unit.
See the table for the minimum extension
lengths for each diameter.
