The precise measurements of angles and the curvature of objects are easily determined using two new Pitch and Roll stages from OES (Optimal Engineering Systems, Inc.) The PR100-45-01 is driven by stepper motors and the PR100-45-02 is driven by brushless servo motors with quadrature incremental optical encoders. The pitch axis (lower stage) is a high-precision […]
Out with the oil, in with the screw
A new generation of electromechanical actuators is replacing hydraulic cylinders in demanding applications. Increasingly, that choice is being driven as much by cost advantages as by performance. Tarek Bugaighis Ewellix Traditionally, when engineers wanted to produce large forces or move heavy loads their first choice would be hydraulic actuation. Today, however, hydraulic systems have a […]
High load capacity actuator from NB Corporation
This compact single axis actuator from NB Corporation features a unique “U” shaped integrated slide guide and ball screw. The BG actuator’s highly rigid structure may be one-end supported. The 4 ball circuits contained in its slide block deliver high load capacity, accuracy and rigidity. The product catalog supplies all dimensions, drawings and ratings necessary […]
FDA-compliant off-the-shelf linear motion components for urgently needed medical products
In dealing with the COVID-19 pandemic many companies have volunteered or been requested to produce urgently needed medical products such as masks, gowns, and ventilators. Tooling up quickly to produce medical grade products for some companies can bring challenges. In addition to needing FDA-compliant materials that will be used in the actual masks, gowns, and […]
New tools, services aid ball screw selection and design
Ball screw performance continues to improve, thanks to advancements in manufacturing methods and materials. Newer generations of ball screws have higher load capacities, which means they’re increasingly being used for applications with higher loads as well as more challenging environmental conditions. Hence, the rise in ball-screw-driven actuators replacing traditional fluid power actuation methods in some […]
Balluff’s new magnetic encoders easily integrate with Siemens motion control systems
Balluff’s new absolute magnetic linear encoders with Siemens Drive-Cliq interface are designed to integrate perfectly into Siemens motion controller environments. Plug-and-play installation makes incorporating them into the drive system easy. The controller automatically detects the sensor and its basic settings. Its automatic status monitoring continuously checks the measurement quality, detecting any mechanical position shift during […]
New linear measurement solution offers programmable option
Encoder Products Company’s (EPC) new addition to their line of linear measurement solutions offers users a spring-loaded mounting bracket combined with a choice of measuring wheel. They then select the encoder to meet their exact application requirements. With up to 10 lb of adjustable spring tension, this spring-loaded mounting bracket fits 2.5-in. shafted encoders with […]
Motorized yaw-pitch-roll stages from OES
Three new high accuracy yaw-pitch-roll stages have been introduced by OES (Optimal Engineering Systems, Inc.) – the YPR100-10-15-01 (stepper-motor driven, pictured below), the YPR100-10-15-02 (brushless servo-motor driven) and the YPR100-10-15-03 (dc servo motor driven). These stages are suitable for the precise measurement of compound angles or the curvature of an object. The yaw axis (bottom […]
New two-axis X-theta positioning system from H2W Technologies
The SRT-030/360-026-01 is a two-axis X-theta positioning system ideal for precision motion control applications that require coordinated linear and rotary positioning. The two-axis system consists of a rotary dc servo motor with encoder mounted to a moving brushless linear-motor-driven positioning stage. The linear axis uses an H2W brushless linear motor, the BLDM-C08, to generate a […]
New 3-axis linear voice coil actuator stage from Moticont
Moticont has released a new three-axis XYZ linear actuator, the XYZ-10. The X and Y axis of the actuator each has 0.97 in. (24.6 mm) of travel and the Z axis has a stroke of 0.500 in. (12.7 mm). The high-speed, high-acceleration, zero-cogging, brushless voice coil motors provide 6.3 lb (28.2 N) of force and […]
