There are three types of Linear Actuators used in manufacturing: Hydraulic, Pneumatic, and Electro-Mechanical. Hydraulic actuators are primarily used for moving very heavy loads, in the same way, that large construction equipment often operates [...]
When selecting a linear guide system, a number of different factors must be considered. First and foremost, the approximate size and load of the system must be determined. Miniature sized profile guides aren’t capable of [...]
A bearing or bushing can be used for linear or rotational motion. While most bearings and bushings are designed for only one type of motion, there are some parts that can combine both. NB stroke [...]
A bushing is a round shaped cylindrical component. It is either equipped with rolling elements (ball, roller) or not and mainly used as a support component in an assembly to reduce machine wear out and [...]
A roller bearing is a cylindrical unit that is used to provide low-friction movement for a bushing or bearing block. A ball bearing is a spherical unit that accomplishes the same objective as a roller [...]
Crossed roller bearings provide more accuracy, rigidity, and weight-bearing capacity for linear motion than other commonly used friction-reducing devices such as ball bearings. And unlike ball bearings, they can support moment loads, radial forces or [...]
How Basic Ball Spline Technologies Affect Performance Before you specify a rotary ball spline, ask the question, “Should the rotary spline nut be riding on angular contact ball bearings or crossed roller bearings?” After ascertaining [...]
Semiconductor labs, in recent years, are billion dollar operations. Accuracy in the automated testing of the semiconductor wafers they produce is a critical part of their fabrication process and a major cost factor. On fabrication [...]
Manned Or Not, This Lunar Project Has A Prototype When NASA Langley Research Center hired Honeybee Robotics Spacecraft Mechanisms Corporation to develop a totally mechanical tool changer, Honeybee was ready. The tool changer was for [...]
“Bearings housed in carriages and tables can ride on round shafts or square profile rails. Here’s a look at the advantages of each when an application demands guided linear motion.” Engineers faced with a linear-motion [...]
