Today we are seeing a major shift from pneumatic linear actuators to electromechanical systems. This is because of high maintenance requirements of pneumatic and hydraulic systems which results in long machine downtimes and lost productivity. But can electrical linear systems truly fill in as a … [Read more...]
Do You Know the Basics of Thermal Expansion?
Motion systems with very long length capabilities like the LoPro® Linear Actuators from Bishop-Wisecarver may require careful evaluation. Thermal expansion is one of the problems that can plague your long motion system application, but it doesn’t have to be! Basics of Thermal Expansion is a … [Read more...]
The Long-Term Advantages of Linear Piston Free Pumps and Aerators
This paper examines the idea of design simplicity as it relates to compressors and vacuum pumps comparing and contrasting conventional design (i.e., motor-driven and diaphragm) with the linear motor free piston system design. … [Read more...]
Selecting Linear Encoder Technology: Design Challenges, Considerations and Solutions
When building a machine, OEMs and end-users are faced with the challenge of finding the highest possible precision technology, while meeting demanding price-performance ratios. Learn more about the challenges designers face and what types of linear encoder technology options should be considered … [Read more...]
How to Build a Better Linear Drive System
With advances in precision manufacturing and the advent of electronic preloading, the accuracy and performance of rack-and- pinion drives can match or exceed that offered by competing hardware – often with better durability, efficiency and economics. This paper outlines four key areas for comparing … [Read more...]
Forms of Closed Loop Stepper Control
This White Paper will explain the three methods that are used to close the feedback loop around stepper motors in a control system. … [Read more...]
Robotics and DualVee® Go Hand in Hand
Robotics and DualVee go together like peas and carrots! Why? Because DualVee can handle high load capacities in all sorts of environments. Did we also mention that DualVee double row ball bearings are internally lubricated as well as sealed and shielded? Say hello to lower maintenance cost! … [Read more...]
Linear Guide Track Designs
The primary function of a linear guide system is to enable an application payload to be easily moved in one linear direction (the linear guide system’s travel axis) while constraining motion in all other directions. Motion constraint is achieved through multiple points, lines, or planes of contact … [Read more...]
Learn how mechanical linear motion hardware affects precision motion control
While there's a lot of focus on electronic controllers that can handle nano-level positioning or multi-axis synchronization, Rexroth explains how choices machine designers make in mechanical linear motion components are critical in achieving the best accuracy possible. Mechanical systems must be … [Read more...]
4-point bearings do triple duty while saving space
A four-point contact ball bearing is ideal for oscillating movement at slow to moderate speeds, and can replace two angular contact bearings. A white paper from Kaydon Bearings, an SKF Group brand, explains the advantages (greater accuracy; space, weight, and cost savings) with design tips. … [Read more...]
