Industrial Rod Locks provide secure locking for a variety of applications. Constructed out of steel or stainless steel, these double rod locks feature two latching points secured by a removable 3/4″ connecting tube and include an inside release for padlocked applications.
A rod lock is a locking device used to safeguard electrical and other cabinet frame parts. It’s commonly found in electric cabinets, communication cabinets, network cabinets, transportation vehicles and other applications where securing the cabinet frame to its door or frame requires added security.
A quality lock should possess several characteristics such as durability, strength and security. It should also be made from superior metal such as steel or stainless steel that can withstand severe conditions while being easy to maintain.
One common way of making locks more secure is by adding spacer elements to each pin bore. A spacer element sits inside each aligned set of pin bores between a master pin, intermediate pin and driver pin; its top and bottom ends are given a slight chamfer for extra protection against detection during proper alignment. This also helps make picking easier!
Selecting the ideal lock is essential for protecting your possessions. There are various types of locks available, each designed for a specific purpose.
Two popular types of locks are combination and mortise locks. Combination locks typically utilize a rotating dial with internal discs to provide multiple combinations.
The Automatic Locking Cylinder Series is ideal for material handling tasks requiring stopping, lifting, and pushing. It boasts a high load capacity and features an innovative locking mechanism that locks in either direction of the cylinder stroke.
This compact design makes installation a breeze, saving space and minimizing the impact of poor air quality on lock performance. Plus, it features a floating taper ring for reliable locking and unlocking operations.
Air-operated rod locks utilize a small bore spring extending a pneumatic cylinder that is activated when compressed air is applied. These units offer superior accuracy and provide a smooth, controlled stroke.
These piston rods feature a low-profile alignment coupler that enables the piston rod to self-center, improving cylinder life. Furthermore, these are ideal for applications with varying temperature and humidity conditions.
Guide Cylinder Series – Pneumatic cylinders in this product category are the “workhorses” of industrial automation. They find widespread application in lifting, pressing, pulling, pushing, clamping, stopping, holding, cutting, and separating processes.
They boast superior strength, resilience, and compact design due to their guiding system. Furthermore, these can be customized for food-grade, heat-resistant, cleanroom, or ATEX applications.
Rod locking cylinders in pneumatic systems provide emergency stopping strength during power outages or disconnections in air supply, protecting heavy machinery and workers from potential fall hazards. They’re also essential during maintenance and repair operations where power loss often coincides with a break or significant drop in supply pressure.
Static rod locks are typically externally mounted onto the front-end cover of a cylinder body. When no signal pressure is applied, internal springs force the piston rod through a cartridge mounted transversally within the rod lock unit to clamp it at any point along its stroke – acting as a brake.
Once a signal pressure is applied, the clamping sleeves rotate back to their unlocked position and enable regular motion. Clamping sleeves feature special groove patterns designed to grip cylinder pistons with high, stable holding force.
When the air supply to a cylinder is interrupted, rod locks provide emergency holding power to stop machinery in its tracks. This is beneficial for both static applications and dynamic ones alike.
The rod’s cycle of movement is coupled with a self-intensifying process that causes its clamping sleeve and locking elements to contract alternately, increasing holding force. Even under heavier loads, this self-intensifying action prevents the rod from shifting from its normal position.
Unlocking the lock requires inserting a key of cross-sectional profile 30 into an opening 29 and featuring a ramp 31 with such an arcuate contour that, when fully inserted, positions all pins 24 in their unlocked positions without penetration into the body 23. This ramp 31 looks like a wave and engages a stub 32 on an inner pin 24 which pushes against spring 27.
Release pins 24 and 21, which were locked into their positions, cause pins 21 to be pulled back into their locked positions and pushed into body 23 in an organized and smooth fashion using ramps 31 located at different points along each profile 30.
The periphery of the locking discs may also be provided with shallow “false peripheral notches” (30), although this arrangement is not necessary and can be omitted to enhance lock security against picking.
Rod Lock Series are position-holding, power-off locking devices designed to provide emergency holding power during a power outage or disconnection of a compressed air supply. They can be stacked together for increased holding force and are compatible with Emerson Numatics NFPA and ISO interchangeable cylinder lines.
The Rod Lock Series provides safety by immobilizing the piston rod under load when the compressed air supply is interrupted. It utilizes a bias normally closed clamp on the rod that holds it securely when there is no air pressure present, avoiding potential accidents as well as damage or loss to your cylinder.
Rod Lock Series mechanical locks boast several advantages over their traditional counterparts, such as superior stability, high-strength construction, and flexibility.
Another advantage is the capability to be operated in a secure manner even when lock pressure loss occurs. Simply releasing hydraulic pressure through the unlock port enables the rod to reengage automatically.
Rod Lock Series cylinder rods are engineered to lock into place if the compressed air supply is interrupted, offering increased safety and dependability in many applications.
These cylinders feature air/spring activation, an internal mechanism that engages to hold the piston rod in place when air isn’t present. Once the air is restored, however, this mechanism disengages, and normal operation can resume.
The RLSS series rod locks offer superior holding capacity with low backlash for linear motion control applications requiring high accuracy. These spring-engaged, air-released units come in both ISO and NFPA sizes.
ZONZEN Rod Locks are the ideal solution for high and low switch cabinet locks, instrument box locks, and communication equipment locks. Crafted with modern technology, these can be used on mechanical cabinets; electrical boxes; metal cabinets; instrument boxes, and safes alike.
