A reader asks: I have heard that new axles no longer need a break-in period. True or false?

Columnist Brian Langenberg provides a current outlook update, key findings from a recent energy sector conference, and takes another look at education and employment.

Many of us have been there; the bearings had the correct preload. You know it, you were there, and you personally saw the measurements. Now, the testing is done and the preload is gone. Not a little gone, not sort of gone - gone, gone. Finger pointing ensues. Suppliers are dragged in by their wrinkly Polo collars. You know the drill. Losing preload in a tapered roller bearing (TRB) system over the life of your application can be a troublesome problem, particularly for gear sets that are prone to noise or severe applications that rely on a very rigid and stable system.

The scene is serene and picturesque. Sunshine reflects off the light chop of the Ohio River, as a barge winds its way into view. While those driving along Louisville’s River Road may be inclined to reach for a camera to capture this idyllic scene, the mood at Nugent Sand Company is anything but tranquil.

What are the best methods to adjust tapered roller bearings?

This article summarizes some common hurdles, issues and questions encountered by the newer and casual users of tapered roller bearings.

More than 27,000 packaging and processing professionals attended Pack Expo 2013 in Las Vegas from September 23–25. In addition to launching new products, creating brand awareness, achieving sustainability goals and generating new business contacts, Pack Expo was an opportunity to engage the next generation of workers in packaging, robotics and processing applications.

This article describes the challenges involved in designing and implementing microstepping systems.

Everything started in 1800 when Volta developed the first DC battery. Faraday used the DC battery to develop the first electric motor. It used brushes to transfer the battery voltage and current to the rotating disk rotor. This was in mid-1831. Thus was born the brush DC motor.
