There are two main types of a recirculating THK ball guide: one that rides on round shafts and one that rides on profiled rails. Because both types are based on recirculating balls, the terminology used to refer to them is very similar and often overlaps. Here’s a breakdown of the most common terms that are used for each one.

A motion control programming system is a straightforward concept: Initiate and control the movement of a load to perform work. They are capable of precise speed, position, and torque control. An application requiring the positioning of a product, synchronization of separate elements, or the rapid start and stop of motion are case examples for the use of motion control.
Such systems are typically comprised of three basic components: the controller, the drive (or the amplifier), and the motor. The controller plans the path or trajectory calculations, sending low-voltage command signals to the drive and applying the necessary voltage and current to the motor, resulting in the desired motion.

Linear rail guides are designed for applications that call for precise motion with high load-bearing capability. But improper mounting can add unnecessary loads, reduce life, and undermine the inherent travel accuracy of the linear guide system. Understanding and following the three mounting specifications described below will help ensure your THK linear guide installation achieves the desired accuracy and doesn’t succumb to premature failure.
Motion controllers are the brains of any motion control system. In feedback-based systems, they take an input command from the user, compare it with a feedback signal from the motor, and take corrective action to bring the output (or actual position) and input (or desired position) in line with one another, ideally with little or no error. Here, we discuss exactly what a motion control board is. (more…)
We are surrounded by things that move in a linear fashion. At THK, their roots lie in the development of a Linear Motion (LM) Guide that can guide a device accurately along a straight line. This manufacturing know-how has let THK continue expanding the range of linear guidance products they produce. (more…)
Motion control is a sub-field of automation, encompassing the systems or sub-systems involved in moving parts of machines in a controlled manner. The main components involved typically include a motion controller, an energy amplifier, and one or more prime movers or actuators. (more…)
The shortest distance between two points is a straight line. But if you are designing a linear motion system, you have to consider structural support, guides, drives, seals, lubrication, and accessories between points A and B. Whether you decide to design and build your LM guide system from scratch using standard parts or buy one that’s engineered for you, making the right choices from the onset should help keep things moving for the long term.

Linear guides have been utilized since the prehistoric age, with paintings of similar guides being used by workers in Egypt, although they did not come to common use as mechanical operatives until the early 20th century. (more…)
