Anti-creep cage cross roller linear bearings result in smooth, flat, and straight motion. The PXL43 series is ideal for use in applications for precision assembly and inspection. Its compact […]
New high-precision, compact linear stage from PI
PI (Physik Instrumente) has debuted a new compact linear stage, the L-509. Providing high precision linear motion with minimized runout, this positioner delivers performance and reliability at minimized cost. Despite its compact dimensions, the stage can handle payloads of more than 20 lb. Available with travel ranges of 26 mm (1 in.), 52 mm (2 […]
What is a crossed roller slide?
As their name suggests, crossed roller slides (also referred to as crossed roller bearings) are linear bearings that use cylindrical rollers—as opposed to balls—to carry a load. The rollers ride between parallel guides in which v-shaped grooves have been ground. The term “crossed” refers to the fact that the rollers are arranged in a crisscross […]
Miniature linear stage delivers higher force density
Breakthrough Miniature Linear Stage delivers five times more force and twice the force density compared to similar competitive products. Dover Motion, a leading technology solution provider for motion control systems, announces the launch of a new product, the XMG Miniature Linear Stage. This new stage is a high-performance version of Dover Motion’s Miniature Moving Magnet […]
Low cost, high precision linear voice coil stages from MOtiCOnt
MOtiCOnt’s VCDS-051-089-01 series linear motion voice coil stages feature a voice coil motor, a ball bearing linear slide, home switch, and an integral optical quadrature encoder with differential outputs. Measuring 13.5 in (342.9 mm) long x 4.00 in. (101.6) wide x 3.755 in. (95.4 mm) high, the VCDS-051-089-01 series stages have a linear travel of […]
New sealed linear actuators for lighter loads
Bell-Everman is now offering a new compact model of their SLS sealed linear stage that keeps contamination such as manufacturing debris, particulate or liquid contaminants outside of the stage housing. The SLS Light model, which measures 80 x 120 mm, has maximum dynamic payloads of 15 kg for the direct drive linear motor version and […]
Linear Stage Features New Drive Mechanism
Bell-Everman’s new ServoSpline™ positioning stage offers a unique drive mechanism that provides backlash-free motion and simplified control. ServoSpline is an extension of a classic rack-and-pinion design that provides simple motion commands and positions the stage in the x- and y-axis by independently driving the two splines. It provides engineers with a reliable stage that is […]
Linear Motion in the Third Industrial Revolution
According to The Economist magazine, a third revolution is coming for the manufacturing industry, ushered in by 3D printing, new materials, and collaborative manufacturing services. Anyone who has watched the 3D printing industry develop over the past decade, or even the past five years, will likely agree. Gartner forecasts that worldwide shipments of 3D printers […]
