NB Corporation’s EXRAIL linear guide has more rollers in less space than other linear bearings, which increases load capacity and disperses the load more evenly. It has longer rollers for greater contact surface and less contact pressure. In comparison to presently available linear guides, the EXRAIL slide guide provides smoother movement. It uses multiple small […]
Tolomatic expands hydraulic-class electric actuator force range to 50,000 lbf
Tolomatic’s expanded extreme-force electric actuator family now includes the RSX128 actuator, rated up to 50,000 pounds of force (222.4 kN). Ideal for replacing hydraulic cylinders and designed for 100 percent duty cycle, the RSX actuator features Tolomatic’s precision-ground planetary roller screws for long, consistent operating life in challenging environments. Applications include assembly, metal fabrication (pressing, […]
Slide ways for precise motion control
NB Slide Ways are non-recirculating linear motion bearings used primarily in optical and measurement equipment where high precision movement is required. The SV style consists of two roller cages with precision rollers in a cross arrangement and four rails with V-shaped raceways. The SVW has one rail with V-shaped grooves on both sides and two […]
Tolomatic develops open-source, low-cost ventilator actuation prototypes for COVID-19 patients
In an effort to support the global need for medical ventilators, Tolomatic has dedicated a team of engineers to the development of highly efficient emergency ventilator concept systems using electric linear actuators. Tolomatic’s solution is a new type of ventilator that operates using an electric linear actuator. These prototypes automate a non-invasive, positive-pressure resuscitator (also self-inflating […]
Dual-axis pitch and roll stages precisely measure curvature and angles
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 […]
