Heavy-duty rod locks

Nexen’s RLSS Series rod locks deliver good holding capabilities with low backlash for demanding linear motion control applications where high accuracy is required. The spring-engaged, air-released series — available in a wide array of standard and custom sizes — features a wide clamping surface to ensure high holding forces even during power/pressure loss.

RLSS rod locks ensure accurate positioning and holding while other operations are performed. The rugged rod locks utilise numerous ball bearings to transfer the spring force onto the clamping collar, resulting in large clamping areas designed to provide a uniform force to the contact area on every engagement. This allows the lock to engage without any rod displacement. Additionally, a cam-operated manual release feature mechanically disengages the rod lock with no special tools needed — just a simple turn of a hex screw using a standard wrench. The default-to-lock function springs back to the engaged position when released.

Available in ISO and NFPA sizes, Nexen RLSS Series rod locks are IP67 rated and withstand harsh industrial environments, including washdown applications. They accept most standard accessories and provide a suitable solution for many applications including robotics, inspection equipment, transfer equipment, injection moulding equipment, food processing, packaging machinery, materials handling, machine tools and positioning equipment.
