How to Estimate Your Linear Actuator Needs with Minimal Application Data?
High moment loads can dictate the use of a dual-rail style linear actuator. Selecting an actuator based on approximations of the performance requirements is arguably more risky than choosing a linear guide or drive with minimal application info. But still, the situation is quite common where a designer or engineer needs a reasonable estimate of the system that will work best for their applicat...
Does my system need high accuracy or repeatability (or both)?
Component selection and machine design affect system accuracy and repeatability. Before we answer this question, let’s define accuracy and repeatability for linear systems. 【Accuracy】 In linear motion, there are two generally categories of accuracy – positioning accuracy and travel accuracy. Positioning accuracy specifies the difference between the system’s target position and the actual pos...
What is sub-divisional error (SDE) in linear encoders?
Accuracy of the interpolation. To determine the position of a linear axis, an encoder read head travels along a scale and “reads” changes in light (for optical encoders) or magnetic field (for magnetic types). As the read head registers these changes, it produces sine and cosine signals that are shifted 90 degrees from each other (referred to as “quadrature signals”). These analog sine and cos...
Linear Systems for Nanopositioning
Piezo actuators, Voice coil actuators, Linear motor stages. When we talk about linear motion, we typically discuss applications where the travel distance is at least a few hundred millimeters, and the required positioning is in the range of a few tenths of a millimeter. And for these requirements, guides and drives with recirculating bearings are a good fit. Case in point: the lead deviation f...
FAQ: What types of linear encoders are there and how do I choose?
Absolute or incremental, Optical or magnetic. Linear encoders monitor linear movement and provide position feedback in the form of electrical signals.

What is racking in gantry systems?
And how can it be avoided… Gantries differ from other types of multi-axis systems (such as Cartesian robots and XY tables) by using two base (X) axes in parallel, with a perpendicular (Y) axis connecting them. While this dual X-axis arrangement provides a wide, stable footprint and allows gantry systems to deliver high load capacity, long travel lengths, and good rigidity, it can also le...
What causes synchronous belt noise and how can it be reduced?
Slience means faster and longer lifetime. Synchronous belts are common in motion systems, providing smoother operation and better high-speed performance than chains and lacking the problems of slipping and stretching that can plague V-belts in precision applications. But one downfall of synchronous, or toothed, belts is the noise they produce. Although quieter than a chain drive, a synchronous...
Take the burden out of managing misalignment in linear motion systems
Guard against causes of bearing failure. No one wants a linear bearing to fail prematurely. While many factors can threaten a bearing’s expected life, designers of industrial machines must especially guard against alignment errors between the bearing rails and moving elements. Not only is misalignment one of the most common causes of bearing failure, it is also among the most costly and comple...
