Mastering Ball Screws Pt. 2: Ball Screw Preloads

Preloading is used to increase the feed accuracy and rigidity of ball screws. Why is this necessary? In many applications utilizing ball screw actuation, position accuracy is of utmost importance. With many ball screw driven actuators, position accuracy can be achieved ...

Mastering Ball Screws Pt. 1: Steel Ball Recirculation System and Characteristics

Ball screws are one of the many components seen throughout factory automation applications. Using the same concept seen with a bolt and nut, this assembly uses the rotary motion of the screw to actuate the nut in a linear direction. ...

Sensor Mounting Part 2: Utilizing Proximity Sensors in Mechanical System Design

Introduction Proximity sensors are a type of sensor that is capable of identifying the presence of an object in a specific region without physical contact. The nature of it being a non-contact type sensor is an advantage because it inherently ...

Sensor Mounting Part 1: Introduction to Sensors and Sensor Mounting

At its simplest definition, a sensor is a device with the ability to detect physical occurrences and changes in the environment, process them as inputs, and then generate an output signal. Sensors play a significant part in the manufacturing industry ...

Linear Guide Tips & Tricks: Removing a block from a rail

Linear guides are a staple component in machine design where linear motion and load transfer is a requirement. The typical structure of a linear guide consists of a rail and a block with recirculating balls inside. The balls are retained ...

Re-examining Precision and Repeatability Criteria in Actuator Selection

One of the main design challenges faced during the early design stages of automated mechanical systems deals with the precision and repeatability needs of components and sub-components.  Sometimes, these two design considerations tend to dwarf all others in becoming the ...

Manual and Motorized Drive Stages

Positioning stages are differentiated by the means used to control the position of the stage platform, either by manual control, via a positional knob, or motor control, via a stepper motor.  These are two of the most common types of ...

Part I: Comparing Rolled Ball Screws and Ground Ball Screws

At a high level, ground and rolled ball screws appear to function nearly identically within a wide range of mechanical applications.  However, the raceway surfaces, which are very similar to traditional machine screw threads found in a typical screw/nut system, ...

Mastering Linear Bushings

Linear motion products are the most commonly used motion elements in the automation of transfer, locating, and assembly machinery. Here, three types of linear guides, Linear Bushing, Slide Guide, and Oil Free Bushing will be compared and explained as we ...

Q&A: Center to Center Spacing for Shafts with Spur Gears

Question: Dear MISUMI Engineering Team: We are currently building a machine that has several timing shafts that are driven by spur gears, but are having problems determining the correct spacing between the shafts. The shafts are held by bearings mounted ...
