Building a motion system that’s heavily reliant on mechanical components can be simple or complex. A few vendors that specialize in mechanical motion components explain what the future holds for these devices that are used everywhere from packaging and transportation to factory automation machines and systems.
Chris Blaszczyk, manager of product development at Misumi (misumiusa.com), says: “Configurable mechanical motion systems now are a reality. Many suppliers are developing assembled systems from their existing stocked products. In addition, the configurable component allows the engineer to specify the critical dimensions of a component in millimeter increments or less. Together, the configurable component and configurable-system concepts are making the machine build and design a quicker, more cost-efficient process. A company can procure a large variety of machined components, such as shafts, linear guides and precision washers, which can be configured without creating a manufacturing drawing.”
Clint Hayes, product marketing manager, Bosch Rexroth Linear Motion and Assembly Technologies (boschrexroth-us.com), says: “As companies strive to increase levels of accuracy in manufacturing, they have begun to replace pneumatic cylinders with electromechanical cylinders, especially in assembly, metalworking, wood manufacturing, packaging and material handling.” In many cases, electromechanical cylinders can provide more control and higher thrust forces than pneumatics can, without the added cost of air handling.
“There is a continuing demand for speed in system-level machine design,” says James Marek, business unit manager, Thomson Systems, Danaher Motion (danahermotion.com). “Combined with an economy that is driving lean business practices, the result is a demand on the supply chain to provide services that were once integral to the OEM. The critical initial phase of the design cycle includes component sizing and selection, engineering analysis, CAD model generation and material procurement. Companies that are leading their respective industries are both timely and cost-effective in developing prototype systems that wow their customers and win the contract. In the mechanical motion component industry, we should see more powerful software tools available to machine designers. These tools will provide services and collateral that will enable engineers to navigate these critical phases of the initial machine build.”
MP-Series integrated linear stages in both ballscrew and direct drive linear motor versions let machine designers choose a solution based on desired performance and not worry about internal technology. By using RSLogix programming software and Allen-Bradley motion analyzer servo system selection and software, OEMs specify load and motion profile parameters to select the appropriate linear stage, and then configure the motion control system to run the stage.

HPLA/HLE belt-driven linear actuators have an MPP motor option that allows users to create a complete system—from actuator to gearhead to motor. The configurable option includes mounting flanges and pinions for the MPP motors, which are field-mountable or factory-mounted.
Parker Electromechanical Automation
DNCE electromechanical screw-driven linear actuator with a non-rotating round piston rod is a drop-in replacement for conversions from pneumatic to electromechanical automation for the Festo DNC and other pneumatic cylinders based on ISO standard 6431. It can be a standalone mechanical axis mounted to a motor or as part of a complete solution with motor and controller. It is offered with a self-braking lead screw with +/- 0.07 mm repeatability or ball screw with +/- 0.02 mm repeatability.
MagnaGear XTR heavy-duty, cast-iron reducer is available with parallel-shaft or right-angle configurations with torque capacities to 920,000 lb-in. for a variety of soft start mechanisms in a variety of conveying applications. It meets or exceeds AGMA and international standards, with carburized, hardened and precision-ground gearing. Tandem HBNR lip seals are standard for extra protection on all bearings
Slip Sliding Away
MDrivePlus linear slides have speeds to more than 60 in./sec with standard linear slide leads of 0.1, 0.2, 0.5 and 1.0 in. travel per revolution. The slide has a precision aluminum guide and wear-compensating, anti-backlash driven carriage with precision rolled stainless steel lead screw. Slots accommodate sensor bracket mounting on the slide, with provisions for mounting a flag on the carriage. An optional sensor flag kit simplifies mounting a common optical sensor.
