1 Selecting and Sizing Ball Screw Drives (October 2012)

The ball screw drive is an assembly that converts rotary motion to linear motion and vice versa. The ball screw drive consists of a ball screw and a ball nut with recirculating ball bearings...

2 Ball Screws Revisited - Ask the Expert (February 2013)

A reader asks for clarification on last issue's Ask the Expert column about ball screw sizing.

3 Oscillation Welding Protects Pipelines (April 2010)

Ball screw assemblies are key to this patent-pending oilfield corrosion prevention solution.

4 CNC System Upgrades (December 2017)

Automated production of large objects such as auto body prototypes, boat hulls and surfboards traditionally requires computerized numerical control (CNC) systems costing nearly a million dollars. Thomson Cuts Costs and Production Time for Autoscale Inc.

6 Linear Motors (October 2016)

When the need arises for linear motion or positioning, there are many choices. One can use an Acme screw, ball screw, rack & pinion, or belts. The cost of a linear motor solution is generally greater than a mechanical linear product, but when one needs highly accurate, repeatable, high-speed motion, then the answer may be a linear motor.

8 Four-Point Bearings Do Triple Duty While Saving Space (March 2015)

A four-point contact ball bearing makes it easy to simplify machine designs that combine radial, thrust and moment loads, because it can handle all three simultaneously. They are primarily used for slow-to-moderate-speed applications, or where oscillatory movement is predominant.

9 Seeking Higher Ground (March 2016)

Even for a toddlin town famous for making “no small plans” — such as, for example, reversing in 1900 the Chicago River to secure clean drinking water, or rebuilding itself seemingly overnight after the devastating “Great Chicago Fire” (1871) — to physically — and successfully — elevate itself as much as 14 feet above its original ground level defies not only description but credulity.

10 Study of Multiple-Point Oil-Jet Lubrication of High-Speed Ball Bearings (June 2014)

The air-oil, two-phase flow inside the multiple-point, oil-jet lubrication ball bearing was studied based on CFD (computational fluid dynamics) theory and technique, and compared with single-point, oil-jet lubrication. The results indicate that the air-oil distribution inside the bearing with multiple-point, oil-jet lubrication is more uniform than single-point injection.

13 Selecting the Right Precision Ball Material for Aggressive Environments (February 2010)

This article will examine the major materials used to enhance balls to resist aggressive environments and help in selecting the right one.

14 Radial Play (Internal Clearance in Ball Bearings) (August 2011)

At first glance, ball bearings are relatively simple mechanisms. However, an analysis of their internal geometries reveals that they are quite complex. For example, the ball to raceway conformity, the radial play, and the number of balls all impact the ability of a ball bearing to support loads under a variety of conditions.

15 How To Use a Hand-Held Micrometer to Measure Miniature and Instrument Ball Bearings (December 2013)

For the most accurate measurements, miniature and instrument ball bearing dimensions should be measured with a calibrated air gauge. A good second option is a calibrated optical comparator. On occasion, it may be necessary to use a calibrated, hand-held micrometer to double-check a measurement or for simple verification while working in the field.

16 Should You Pay a Premium for a Mounted Ball Bearing (December 2013)

Mounted ball bearings are everywhere in industrial applications. They serve critical roles in keeping a manufacturing operation running smoothly and in ensuring that equipment functions properly and reliably. So why might it be advisable to spend significantly more for a dimensionally comparable bearing from one supplier versus another?
