At first, those components are easy to overlook. Motors get the attention, controls get the tuning, and software handles the complexity. But when performance issues begin to appear, unexpected vibration, inconsistent positioning, and premature wear, the focus shifts to what is physically connecting it all. Worn couplings, misaligned shafts, and undersized gearboxes often reveal the root cause. 

As improvements are made, the results speak for themselves. Properly matched gearboxes improve torque and efficiency. Precision linear motion components deliver smoother, repeatable positioning. High-quality belts, pulleys, and couplings reduce stress across the system, extending equipment life and minimizing downtime. What was once overlooked becomes essential. 

What seems like a small shift in perspective becomes something much more impactful: a deeper understanding that reliable motion does not happen by chance. It is built into every component in the system. When power is transmitted effectively, everything downstream performs better. 

AutomationDirect offers a comprehensive lineup of mechanical power transmission products designed to keep your systems moving with precision and reliability. From gearboxes and linear motion systems to timing belts, pulleys, and shaft couplings, these components are designed to optimize torque, speed, and motion control across a wide range of applications. 

We offer FREE shipping and FREE technical support for all products we sell, and offer a 45-day return policy on most products. You can TRUST AutomationDirect to deliver dependable solutions that keep your equipment running smoothly.

June 24, 2026 – AutomationDirect has added more I/O modules for the Productivity2000 PLC series. New combination I/O modules deliver increased flexibility and efficiency by integrating multiple input and output points into a compact footprint, helping reduce both panel space and overall system cost. Available options include DC input modules paired with sinking or sourcing transistor outputs, along with relay output versions for applications that require reliable switching of higher voltage or current loads, giving designers the freedom to match the module to their exact control strategy.

Expanding output performance, the new 16-point solid-state relay module enables high-speed, high-cycle switching with extended operational life and reduced electrical noise, complementing existing solid-state offerings for demanding applications. Additional analog input modules provide high-resolution 16-bit performance with channel-to-channel isolation, allowing mixed signal types and improving noise immunity in environments where signal integrity is critical.

Enhancements to Productivity Suite further extend system capabilities by adding Structured Text programming alongside Ladder Logic, allowing developers to select the most effective programming method for each task or combine both within a single project. New UDI Libraries simplify the reuse and standardization of proven code structures, while the added Delta contact function enables easy detection of changing conditions between program scans. Together, these updates streamline development, reduce engineering time, and provide greater flexibility for building robust, modern automation systems.

June 24, 2026-AutomationDirect now offers Wachendorff 58V and 36J series encoders that sport both IP67 and IP69K ratings, making them well-suited for high-pressure, high-temperature, washdown environments. IP69K is essential for sanitation compliance and protects against dust and intense, close-range liquid jets, including those used for high-pressure steam cleaning. The 58V models have additional resistance to acidic and alkaline cleaning agents, including salt mist.

Wachendorff encoders offer fixed resolutions from 60 up to 5000 PPR with universal, open collector, or line driver outputs for flexible connectivity. These heavy-duty models withstand shaft loading to 300 N (36J models) or 100 N (58V models) for reliability and longevity in demanding industrial environments. Their extreme service life (30 billion revs (36J) and 10 billion revs (58V)) allows for reduced maintenance, enhanced uptime, and long-term cost efficiency.

Combine a 58V or 36J heavy-duty encoder with a measuring wheel and a spring-loaded swing arm to easily create a measuring wheel system. MR series wheels are now available in 200mm and 500mm circumferences with a variety of contact surfaces. WDGM spring-loaded mounts are available with clockwise or counter-clockwise swing arms, as well as a straight-sliding version to fit any measuring wheel application. All assembly hardware is included, and a wide range of mounting angles and orientations is possible.
