LINEAR MOTION CONTROL
Technical Data Sheet

Rod Locks
RLSS Series
Nexen’s new generation of linear holding/locking
devices take rod locking technology to the next
level. With superior performance, these springengaged, air-released units supplement air
cylinders and guide rods for holding in poweroff/e-stop situations. High clamping forces
ensure positive holding with minimal air required
for release. Choose from our standard products,
or we will work with you to meet your unique
application specifications.

Precision Operation Maintains Accurate Positioning
The RLSS series of Rod Locks guarantees accurate positioning and provides
precision holding while other operations are performed. The Rod Lock engages
without causing any rod displacement, and also features extremely low backlash
making them ideal for precision applications.

Large Clamping Surface Ensures Consistent Performance
The RLSS line is designed with a large clamping surface that provides uniform
force to the rod contact area on every engagement. The clamping mechanism
utilizes numerous ball bearing to reduce friction.

Spring-engaged Units Engage in Power-off Situations
Nexen’s Rod Locks are spring-engaged, so they operate even in power-off
situations to promote safety for operators and machinery. Multiple springs ensure
reliable performance and redundancy. The fast response time of these springengaged products also increases positioning accuracy. Nexen’s Rod Locks also
feature locking mode sensing capability that allows engagement/disengagement
feedback with the use of an optional inductive sensor.

Sealed to Withstand Harsh Environments
Every RLSS Rod Lock is sealed to protect internal components. These seals are
designed to withstand even harsh wash-down environments and are IP67 rated
(anodized models exceed NEMA 4X rating). Rod Locks are available in natural
brushed aluminum or with a black anodized coating.

Manual Release
The cam operated manual release feature mechanically disengages the rod lock
with the simple turn of a hex screw using a standard wrench. The default-to-lock
function springs back to the engaged position when released.
