Non-magnetic Encoders for High Magnetic Field Environments from NUMERIK JENA
Jena, Germany – NUMERIK JENA, sister company of HEIDENHAIN, now offers a line of linear and rotary encoders that are non-magnetic and that have been tested in environments up to 6 Tesla and have no influence on the machine environment. The encoders also can withstand this high magnetic environment without loss of accuracy or resolution […]
Accuride Expands Self-Closing Slide Options
Accuride announces the addition of model 3832SC, another self-closing slide option designed with a lighter pull-force for use in less demanding applications such as medical or supply carts and industrial workstations. The self-closing action is achieved through a spring-loaded device that activates about 1-1/2 inches from the closed position. This integrated device is designed to […]
Nippon Pulse Introduces Green Drive Linear Actuator
Nippon Pulse has announced the introduction of its newest linear servo product, the Green Drive linear actuator. The Green Drive is an all-inclusive linear direct drive actuator suited for high-performance applications requiring high force, accuracy, and precision. Features of Nippon Pulse’s Green Drive include: • Acceleration (peak) force of up to 600N for 40 seconds […]
Moog’s hybrid electric-hydraulic actuator offers efficiency and reliability
Moog (www.moog.com) presented a prototype hybrid electrohydrostatic actuator (EHA) that avoids the mechanical gearing and screws usually needed for purely electric actuators during the SPS/IPC/Drives show in Germany. The EHA, unlike conventional hydraulic actuators, needs no hydraulic piping, therefore improving reliability and cutting costs. The actuator uses Moog’s hydraulics and electrical expertise which are applied […]
Bosch Rexroth’s New Ball Rail System for Humid to Wet Production Environments
Charlotte, NC – Bosch Rexroth’s new NFRG ball rail system is well-suited for use in humid to wet production environments. The profiled rail and the ball runner block are both made entirely of corrosion resistant steel according to DIN EN 10088 and of certified plastics according to EU Directive 2002/72/EC and US Regulation FDA21CFR. The […]
What is linear motion design engineering? Technical summary
Linear motion is an area of motion control encompassing several technologies including linear motors, linear actuators, and linear rolling guides and bearings, among others. Linear motors — an accurate option Traditional linear motors are basically a permanent magnet rotary motor rolled out and laid flat. It’s as if the stator and rotor were cut along […]
What are roller chains? Technical Summary for Motion Engineers
Updated April 2015. || In any motion control system, the object is ultimately to move some kind of load. The component in the motion system that converts electrical energy into mechanical energy is the motor. But the task doesn’t end there. A motor’s output shaft has to connect somehow to whatever the load is. This […]
What are Linear Bearings?
Linear bearings generally use a pad, bushing, or roller system to carry a load on a rail that need not be a straight line. The rail can be most any length, although that dimension is limited by the actuator. The durability of the bearing is determined by the load and required speed. Furthermore, rails can […]
Lead Screw Basics
A lead screw, also known as a power screw, is a threaded rod or bar that translates rotational motion into linear motion. When it comes to translating the rotary motion of a motor to linear motion, there are many different ways of accomplishing this task. Often times in the world of motion control, the battle […]
