Advanced Machine & Engineering Co., a manufacturer of stand-alone and NFPA cylinder mount pneumatic rod locks since 1994, has now introduced the Amlok RLI, its fourth-generation power-off rod lock. This basic lock unit is in addition to the RLN and RCH, expanding the company’s rod lock product line. The RLI Metric (ISO 6431) series will complement the standard NFPA line. This fourth-generation lock is the culmination of 18 years of manufacturing and marketing of pneumatic and hydraulic rod locks.

The rod lock’s standard features include anodized aluminum construction, a heavy-duty clamp system and power-off clamping. The standard seal material is carboxylated nitrile.

The unit uses dry-filtered air, has a release pressure ranging from a minimum of 4 bar/60 PSI to a maximum of 8 bar/120 PSI. The operating temperature ranges from 10 degrees F to 180 degrees F. Maximum rod tolerance is +0.000 in./-0.002 in.

Rod lock options include stainless or electroless nickel-plated housing, viton seals, wiper scraper and sealed versions. The lock mounts to standard ISO 6431 cylinders or can be stand-alone using MXO, MF1, MF2 and MS1 mounting configurations.

The Amlok RLI is available in various sizes for rod diameters of 16 mm, 20 mm, 25 mm, 32 mm and 40 mm and cylinder and bore diameters from 40 mm to 160 mm. Holding forces range from 200 lbs/890N to 2,450 lbs/11kN.  

The RLI power-off pneumatic rod locks are particularly-well suited for holding applications in industries such as automotive, mobile, food, machine tool and military test, among others.
