For the Seabees, hazardous construction zones have always been part of the job.

SKF energy-efficient bearings, Bishop Wisecarver guided motion system, Weiss torque rotary table, Mico wireless braking system, Nord worm gear series, and SKF expanded range of couplings.

With today's smaller, hotter - and overloaded - machinery, specifying the correct lubricant is vital.

Even when the critical components of industrial power transmission gear drive systems are properly designed, specified and manufactured consistent with application requirements, performance problems can develop over time and failure may follow.

When selecting an open gear lubricant for use in a particular application, the method of application used must be considered.

It is a simple fact: better lubrication can lead to dramatic energy savings and an improved bottom line. This ought to interest any plant manager who is looking for ways to reduce operating costs, and it is especially significant at a time when stricter government regulations are in direct contradiction to reducing costs. Lubrication reliability is the solution; this article will describe how manufacturing plants can use “lubrication reliability best-practices” to reduce their energy consumption, emissions and operating costs—all at the same time.

CONEXPO/CON-AGG and IFPE 2011 attracted nearly 120,000 attendees.

Despite posting its slowest quarter since early 2007, AWEA remains optimistic that the wind industry can and will work successfully with the revolving doors in Washington.

One of the driving forces behind the industrial revolution was the invention—more than a century ago—of the electric motor. Its widespread use for all kinds of mechanical motion has made life simpler and has ultimately aided the advancement of humankind. And the advent of the inverter that facilitated speed and torque control of AC motors has propelled the use of electric motors to new realms that were inconceivable just a mere 30 years ago. Advances in power semiconductors—along with digital controls—have enabled realization of motor drives that are robust and can control position and speed to a high degree of precision. The use of AC motor drives has also resulted in energy savings and improved system efficiency. This paper reviews the development and application of inverter technology to AC motor drives and presents a vision for motor drive technology.
