Edited by Mike Santora In machines for industrially manufactured bakery products, product changes must be flexible, precise and repeatable. This requires precision with numerous set-up and adjustment options. Siko integrated fieldbus positioning drives into the new “Soft Star CTi” dough dividing and molding machine, which combines the motor, transmission, absolute measuring system, control and power […]

Rexroth ball-screw assemblies increase service life by 80%
Bosch Rexroth now offers an 80% increase in the service life of its ball-screw assemblies thanks to continuously improved production processes. Design engineers can use smaller sizes for the same power requirements. Delivery times have also been shortened through the digitalization of engineering process, as well as optimized logistics. As a leading manufacturer of linear motion technology, […]
Option for fine-stroke adjustment improves linear-drive reversal point accuracy
Amacoil-Uhing Model RG linear drives now feature an option for fine adjustment of maximum travel distance. On the standard Amacoil-Uhing drive assembly, the end stops limiting travel distance are set by hand. With the new option, the end stops ride on threaded rods with control knobs on both ends. Turning the rods moves the end […]
Actuators with haptic feedback: Ultra-thin PiezoHapt actuator with low driving voltage
TDK now sells a new haptic component — a new ultra-thin PiezoHapt actuator featuring a short response time of just 4 msec. PiezoHapt has a unimorph design consisting of a multilayer piezo element bonded to one side of a vibration plate. With a thickness of a mere 0.35 mm the new haptic actuator is much thinner than conventional eccentric […]
Direct-drive linear motors with integrated encoders offer resolution to 1.25 µm
Moticont has added two linear motors to its SDLM Series of high-speed direct-drive linear motors. These compact drives with a 1.0 in. (25.4 mm) stroke are just 1.00 in. (25.4 mm) in diameter and 3.75 in. (95.3 mm) long. These direct-drive linear motors feature resolutions of 5 µm (0.000197 in.) and 1.25 µm (0.000049 in.) […]
ETEL expands linear motor line
As engineers expand their range of machines to a point where a larger payload is required, an upgrade of their linear motors may be necessary. So, to make their design process easier, ETEL has added extra ironcore linear motor lengths to each of their different widths. These new lengths are compatible with existing 50, 70, […]
Second-gen electromechanical cylinder from Rexroth features a hygienic design
Rexroth has expanded its compact drive offerings, with the second generation EMC electromechanical cylinder. Featuring a hygienic design and IP65 protection class, they are suitable for applications with frequent cleaning cycles in the food industry. The new size EMC100-XC-2 increases the power density for feeding forces of up to 56 kN, particularly for applications in […]
Motion system applications: Better ballscrews, more applications
Ballscrews suit applications needing light, smooth motion, applications requiring precise positioning, and when heavy loads must be moved. Examples include machine tools, assembly devices, X-Y motion and robotics. Factors such as lead accuracy, axial play and preload, and life-to-load relationship are most commonly used to classify ballscrews. Lead accuracy is the degree to which the shaft’s […]
Where linear motors improve designs: Application example in multi-axis stage
Machine-tool applications and the manufacture and assembly of semiconductor components account for more than half of all linear-motor use. That’s because linear motors are precise (albeit costly compared to other linear-motion options). Other applications for these relatively new motion components also include those that need fast and precise positioning or slow and extremely steady strokes. […]
ELP electric linear module from SCHUNK for user-friendly operation
The SCHUNK ELP can be adjusted in two simple steps making it the most user friendly electric linear module on the market. The end positions can be mechanically adjusted with a screw and the speed of extension and retraction is adjusted using rotary switches on the side of the unit. More after the jump. Speed […]
