| Rod Lock Series RL |
 |
For cylinders ISO 6431/VDMA and ISO 6432*
Series RL ø : 20, 25, 32, 40, 50, 63, 80, 100, 125 mm
|
The Series RL rod locks are available
in 9 different sizes to fit (DIN/ISO 6432)
cylinders 20-25 mm diameter
and (DIN/ISO 6431 VDMA) cylinders 32, 40,
50, 63, 80, 100 and 125 mm diameter.
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. g. and apply in
both directions. When operating the cylinder to
achieve intermediate stroke positions, a 5/3
pressure center valve should be used.
The piston rod should remain in the locked
position when the directional valve is in the
mid position. 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.
