The new SP Series high-performance miniature ball screws from SKF Motion Technologies have been optimized to deliver precise positioning, excellent repeatability, and smooth-running and quiet linear actuation. Their advanced internal ball recirculation system and thread design additionally enable higher speed capabilities and longer operating life compared with conventional rolled ball screws. These small packages ultimately […]
High-performance XY stage with linear servo motors from InteLiDrives
New IntelLiDrives XY stage design allows critical elements such as orthogonality, straightness, and flatness to be optimized, resulting in a stage with exceptional geometric tolerances. Direct-drive technology with core-less linear servo motors has no hysteresis or backlash, enabling accurate and repeatable nanometer scale motions in both X and Y directions. Non-contact direct-drive technology offers robust, […]
HEIDENHAIN debuts multi-section linear encoder for use with ACU-RITE’S digital readouts
HEIDENHAIN announces the addition of the AMO LMF 9310 multi-section linear encoder to its line of robust linear encoders. This TTL encoder is specifically designed for long length applications (over 10 ft) on manually operated machines and is compatible with HEIDENHAIN’s ACU-RITE brand of digital readouts. The AMO LMF 9310 is a replacement for the […]
Thomson extends Electrak HD smart actuator line to 16 kN loads
Thomson Industries, Inc. has extended the capability of its Electrak HD electromechanical linear actuator line to loads of up to 16 kilonewtons (kN) (3,600 lb.) This new offering delivers heavy load handling capacity comparable to hydraulic technologies but with greater controllability, smaller footprint and low maintenance. The Electrak HD expansion also sets a new stroke […]
H2W develops highest force voice-coil actuator
H2W Technologies has developed what it says is the world’s highest force commercially available non-commutated DC linear actuator, otherwise known as a direct drive voice coil actuator. The model NCC08-75-3000-3X is capable of generating a continuous force of 300 lb (1,330 N) and a peak force of 900 lb (4,000 N) at a duty cycle […]

Other features include repeatability to 50 microns and loads to 30 kg. The […]
What are planetary roller screws?
Screw drives are some of the most common methods of mechanical linear actuation. And planetary roller screws are one of several screw types, including lead screws and ball screws. Planetary roller screws use threaded rollers that are toothed to mesh with geared rings at each end of a nut. The rollers spin on their axes […]
