How paper-thin electroadhesive linear brakes can unlock significant power and weight savings in new and legacy linear motion systems. Kirby Witte VP of Engineering ESTAT Actuation Linear motion systems must pack all the right features and components in increasingly compact designs. Brake technologies are a critical part of this puzzle, providing load holding, emergency stopping […]
Pre-loaded systems deliver precise positioning for machine tools
Redex’s patented DualDRIVE and TwinDRIVE preloading technologies now give CNC machine designers several ways to build a zero-backlash system. These approaches leverage Redex modular SRP, DRP, KRP and KRPX Series rack and pinion reducers whose output pinions are preloaded against the rack to eliminate backlash — a longstanding challenge with designs that require long axis […]

Tolomatic’s new Drive Integration Tool combines the motor, drive, feedback and connection information across a wide range of industry-leading manufacturers with Tolomatic’s own servo linear actuator specifications. By […]
New mini hexapod from Aerotech with 6 degrees of freedom
Aerotech Inc.’s new HexGen HEX150-125HL Miniature Hexapod is a six degree-of-freedom (DOF) precision positioning system. This compact, cost-effective hexapod, with a 150-mm base diameter and a nominal height of 125 mm, achieves minimum incremental motion to 15 nm and payload capacity up to 12 kg for applications requiring multi-DOF motion – especially those with constricted […]
Photonics alignment systems feature motion in 4 and 6 degrees of freedom
PI’s new F-141 photonics alignment system provides high throughput with motion in 4 and 6 degrees of freedom for industrial test and assembly of photonic integrated circuits (PIC). This ultra-compact precision alignment system fits inside a space of approximately 5 by 7 by 4 in. (W x L x H) while providing 40 mm of […]
High-precision dual-axis Alpha-Beta goniometers from OES
OES (Optimal Engineering Systems) has released a new series of dual-axis high-precision Alpha-Beta stages capable of rotating an object around a fixed point in space on a spherical surface. The AK150-10-15-01 Dual-axis Goniometer Stepper Motor driven stage (pictured) features +/- 0.01 degrees repeatability, 0.05 degrees accuracy, and 0.0006 degrees resolution with a 10 micro step-per-step […]
