The NB rotary ball spline has a cylindrical nut that rolls on the ball spline shaft. Rotary ball splines can be used for both rotational motion and linear motion, providing sub-millimeter accuracy every time. Popular applications include SCARA robots, the vertical shaft of assembly equipment, automatic tool changers, and loaders. A ball spline’s forte is […]
Under development: Linear stroke-extending technology from Ascending Power
In a recent email exchange with London-based John Hammerbeck of Ascending Power, we learned more about a novel new linear-motion extension technology from the company. The actuator steps up a short input stroke to a long output stroke using either kinematic linkages or permanent magnets. Below is a SolidWorks animation of the linkage variation; depending […]
Compact voice-coil motors from Moticont with 1.0-in. diameters for myriad stroke requirements
Moticont now sells linear voice coil motors (LVCMs) in two 1-in. (25.4-mm) diameter motors. • The LVCM-025-022-01 has a stroke length of 0.375 in. (9.5 mm) a mid-stroke length of 1.30 in. (33 mm) and a high-force-to-size ratio of 16.9 oz (4.7 N) and a peak force of 53.5 oz. (14.9 N) at 10% duty […]
Heavy-duty but lightweight slide is a solution for transportation and industrial uses
Accuride International announced the U.S. launch of its AL4160 Super Heavy-Duty Aluminum Slide – a strong but light solution that combines a full aluminum body with stainless steel components for diverse transportation and industrial applications. “We designed the AL4160 to address a market need for a slide that supports heavy loads and performs in harsh environments but […]
Take the burden out of managing misalignment in linear motion systems
No one wants a linear bearing to fail prematurely. While many factors can threaten a bearing’s expected life, designers of industrial machines must especially guard against alignment errors between the bearing rails and moving elements. Not only is misalignment one of the most common causes of bearing failure, it is also among the most costly […]
Low-profile linear stepper motor stage from H2W Technologies
The LSS-016-04-006-01A-ME is one of a revolutionary new series of low-profile linear stepper motor positioning stages that integrates an absolute linear encoder and a single-axis linear stepper motor stage. This enables the linear stepper motor stage to operate as a 2-phase brushless linear motor when coupled with motion control electronics provided by H2W Technologies (H2W). […]
