Improvements in lead screw designs have meant screws that are increasingly competitive with other types of drive screws, including ball screws. For instance, lead screws can offer shorter lead times and better performance, all at a lower cost than other screw technologies. Quite a few lead screw manufacturers offer a range of anti-backlash options, superior […]

Motion Trends: 3D printing aides lead screw design, prototyping
A number of trends in the motion industry are impacting lead screw design and implementation. One of these is the miniaturization of components. For instance, applications in optics as well as medical devices demand high precision, and smaller miniature lead screws can meet high precision specifications and can fit where space is limited and where […]
3DP leadscrew nut insert from Haydon Kerk boosts accuracy of 3D-printed prototypes
Now, a 3DP (3D-printed) leadscrew-nut insert prototype service from AMETEK Haydon Kerk gives machine builders a way to verify linear-motion design iterations quickly and more accurately. Engineers typically do not have access to 3D printers to do this prototyping. Instead, most of them contract with a third party to get quick turnaround on parts. With […]
Can-stack linear actuators: How the motor and screw components work
Can-stack linear actuators are one type of stepper-motor design that converts rotary to linear motion with a built-in leadscrew. The linear actuators incorporate can-stack motors — sometimes called claw-tooth step motors, tin-can stepper motors, or claw-pole motors — leverage low-cost construction with punched sheet-metal parts that form toothed (or clawed) cups surrounding bobbin coils. Common […]
Haydon Kerk adds mold flow Analysis software for rapid custom lead screw nut solutions
Haydon Kerk Motion Solutions recently added a powerful mold flow analysis software to help with the design of custom-molded lead screw and linear motion components. Solid Works Plastic Professional is an engineering tool used by Haydon Kerk’s experienced tooling engineers to help speed up the design process and offer customized solutions to fit customer’s application […]
How to size and use stepper motors that integrate rotary-to-linear motion?
No motor subtype satisfies all applications, as all have their own benefits and drawbacks. Even so, axes that need incremental strokes often use dc motors that are either stepper or servomotors. Very advanced designs incorporate linear motors to do away with gearboxes, belts and pulleys, ballscrews, leadscrews, and other power-transmission components — for high accuracy […]
What’s the use of a force versus linear velocity chart?
Force versus linear velocity charts are mainly a tool for engineers specifying screw-based linear actuators. In short, the charts help engineers pick the actuator screw resolution after settling on a given actuator frame size. Much like references that describe the capabilities of rotary motors alone, there are similar metrics that describe the capabilities of linear […]
New motorized linear stages from Haydon Kerk
Haydon Kerk Motion Solutions has announced the release of its new line of WGS motorized linear stages. The WGS line is now directly integrated into Haydon Kerk’s step motor family using its patented design. The motorized WGS can be ordered and shipped within 24 hours from the Haydon Kerk e-commerce website at www.haydonkerkexpress.com. The WGS […]
7.5 resources every design engineer should have
A design engineer often has to be a jack-of-all-trades, with good working knowledge of statics, dynamics, materials, and manufacturing, in addition to their “real” area of expertise (packaging, dispensing, etc.). And while most of us long ago forgot the bulk of what we learned in engineering or technical school, design engineers use those concepts and […]
Haydon Kerk Motion Solutions releases 2016 linear motion catalog and design guide
Haydon Kerk Motion Solutions, a brand of AMETEK® Precision Motion Control, has released its new linear motion Catalog and Design Guide, revised for 2016. The new catalog has been updated and expanded with new product sections, including the WGS06 linear rail, the brushless IDEA servo motor controllers, Size 8 double stack 21000 linear actuators, ZBM […]
