Ride the wave of electrification: Off-highway designs with linear actuators
The transition of mobile machinery and off-highway equipment away from fossil fuels may be a long-term goal, but electrification is already delivering real benefits in the sector. By Tarek Bugaighis • Ewellix Is the era of the internal combustion engine coming to end? Under pressure to reduce harmful emissions, the automotive industry is already gearing […]
What factors contribute to air bearing stiffness?
According to the American Society of Mechanical Engineers (ASME), stiffness is: The capacity of a mechanical system to sustain external loads without excessive changes of its geometry (deformations). When we think of stiffness in traditional bearings with rolling elements, we’re typically considering the deflection of the carriage when a load is applied. For air bearings, […]
Direct-drive rotary servo tables feature large aperture
The ACR-490UT precision rotation stage from IntelLiDrives is a low-profile rotary table with high-speed direct-drive rotary servo motor that features a large 490-mm center aperture and lightweight construction. This makes it a suitable choice for a host of applications, from precision indexing to high-speed laser machining to handling large diameter silicon wafers for semiconductor processing. […]

Bosch Rexroth precision modules meet requirements for clean production
With a sealed Ball Screw Assembly on both sides and an upgraded lubrication concept, the new Precision Module PSK from Bosch Rexroth – manufactured in the United States, meets the operational requirements of semiconductor production and of the electronics industry even better than before. In this new generation, designers have increased the rigidity of the […]
Motorized vertical lift stages feature high load capacity, high precision
OES (Optimal Engineering Systems, Inc.) has added 3 high precision vertical lift stages capable of elevating heavy loads by 30 mm (1.18 in.) in an ultra-low profile design. The rigid box construction of the moving component of the elevator stage travels on six slide rails assuring smooth vertical travel and parallelism of the table and […]
Nanopositioning controller for piezo stages boasts 270-W peak power, nanometer-level precision
A high-power version of PI’s (Physik Instrumente) E-727 family of multi-axis piezo nanopositioning controllers provides 270 W of peak power – close to 10X of the standard version. The enhanced performance is useful for dynamic, nanometer-level precision motion and positioning applications, such as FSM (fast steering mirrors) in free space optical communication and laser material […]
Linear actuators automate shampoo-bottle filling with less drips
Consider the equipment that fills shampoo bottles. Automatic Liquid Filling Manufacturing machines use conveyors to transport empty bottles to sensor-tracked wait positions. Then they insert shampoo-dispensing nozzles into the bottles and slowly raise those nozzles as the liquid rises during dispensing. Holding a constant distance between the nozzle ends and liquid surfaces prevents the shampoo […]
Industrial gas springs help in fight against COVID-19
Gas springs, also called gas dampers, tension springs, gas-pressure springs depending on the setup and context, are compressed-air or oil cylinders that install in motion designs to damp forces and return kinematic linkages and more complicated assemblies to default positions. Gas springs work through a piston on the end of a rod that protrudes from […]
