NB Corporation presents a compact, single axis actuator with a unique “U” shaped integrated slide guide and ball screw. The BG actuator’s highly rigid structure may be one-end supported, and the four ball circuits contained in its slide block deliver high load capacity, accuracy, and rigidity. To accommodate a wide range of installations and applications, these […]

35-mm CBL35C programmable electric moving-coil servo actuator from SMAC Corp.
Now a 35-mm-diameter SMAC Corp. CBL35C electric cylinder has a built-in controller. The latter lets the CBL35C control force, position, and velocity — and facilitates simple installation. The actuator works for applications with limited space but needing accurate control … Plus the CBL35C provides significantly longer life, programmability, high speed, accuracy, and energy efficiency maintaining […]
New linear motor designs improve speed and positioning
Linear motors enable maximum precision and dynamic performance in various motion control tasks. These include not only rapid traverse, but slow, constant speed traverse of machine heads, spindle slides, tool management systems, part handling devices and more. There are considerable cost savings to be realized when various mechanical components are replaced by simple and efficient […]
Lead screw sizing in 4 steps
Lead screw sizing is a bit of a hybrid exercise, with similarities to the process of ball screw sizing, but incorporating some of the considerations that come with sizing a plain bearing. While many factors are involved in the selection of a specific lead screw assembly, lead screw sizing — choosing the right diameter and […]
Video: Schneider NEMA 14, 17, and 23 linear actuators (with external and non-captive screws)
In a recent video with our esteemed colleague Lee Teschler, we got to look at six linear actuators from Schneider Electric Motion — in NEMA sizes 14, 17, and 23. These linear actuators incorporate single-stack stepper motors to deliver long life and high accuracy and repeatability. The compact IP20 motors are 1.8° step-angle motors pre-integrated […]
LINAK has completed expansion of U.S. manufacturing facility
U.S. subsidiary of Denmark-based LINAK has now completed an addition to their North and South American headquarters in Louisville. The expansion sets LINAK up for continued growth and allows for greater commitment to the Louisville area and its U.S. customers. “LINAK’s work in advanced manufacturing, one of Louisville’s traditional strengths and a key component to […]
PV Equation: How to calculate the PV value for a lead screw application
Lead screws rely on sliding friction between the nut and the screw to convert rotary motion into axial (thrust) force to move a load. Most lead screw designs use either a carbon steel screw with a bronze nut, or a stainless steel screw with a plastic nut. In either case, there are no recirculating balls […]
Warner Linear new rugged-duty B-Track K4x actuators for demanding industrial applications
The new B-Track K4x model provides the highest load rating in its class with a ball nut screw for a 4,000-lb (17,760 N) load capability in a compact package size. The units work in demanding applications where an alternative to hydraulic or air cylinders is needed or where hydraulic power sources are unavailable. Suitable applications […]
Which timing belt tooth profile should I use: Trapezoidal, curvilinear, or modified curvilinear?
Timing belts — also known as synchronous belts or toothed belts — are most often used in transporting, indexing, and positioning applications where high torque or force transmission and high acceleration rates are required. Unlike V-belts, which rely on friction between the belt and the pulley for power transmission, timing belts have positive engagement between […]
New integrated motor/actuator series from Curtiss-Wright
Curtiss-Wright’s Sensors & Controls Division recently announced the release of the Exlar GTX080 next-generation integrated motor/actuator. The GTX080’s latest design offers substantial performance improvements over its predecessor. Incorporating Curtiss-Wright’s patented inverted roller screw technology, the GTX080’s high power density and compact form factor make it an ideal replacement for hydraulic cylinders. The GTX Series actuators […]
