Timken Debuts Report On Its Global Citizenship


Timken has released its first-ever Global Citizenship Report, which highlights the company’s strategies and goals, as well as its achievements during 2008. According to the report, a sampling of Timken’s environmental achievements over the past year include:

  • A recycling process has eliminated 21,000 tons of electric arc furnace dust from being sent to landfills.
  • A new wind bearing facility in Xiangtan, China is well on its way toward certification as a green building, following the standards of the LEED rating system (Leadership in Energy and Environmental Design).
  • A program to eliminate PCBs from all Timken facilities was completed in March 2009, six years ahead of schedule.

“We know that global citizenship touches every aspect of our business and underscores the policies and practices for which we hold ourselves accountable,” said Chairman Ward J. “Tim” Timken, Jr. “By continuing to grow our enterprise in ways that build sustainable value, we help to fulfill our responsibility to our associates, customers and all business interests, including our communities and the environment.”

The full report is available for download on the Timken Website.

Maintain Wind Turbine Efficiency


LUDECA’s latest brochure, “Maintain Wind Turbine Efficiency,” describes how predictive and preventive maintenance solutions, such as shaft alignment, geometric measurement, vibration analysis, balancing and online condition monitoring equipment, can help improve wind turbine reliability while reducing downtime and maintenance costs.

Included in the brochure is the LEVALIGN® laser that can be used to  measure the profile of flanged surfaces found in major wind turbine components, including tower segments and the nacelle-hub assembly. Likewise, the high-precision electronic inclinometer INCLINEO® is suited for the precision measurement of horizontal surfaces.

The brochure also highlight’s LUDECA’s shaft alignment systems, that are capable of performing measurement under space constraints with high accuracy, and autonomous online systems, which detect both mechanical and electrical faults at an early stage.

Wind-Tower Welding Arc Flux


Lincoln Electric has introduced Lincolnweld® WTX™, a submerged arc flux designed to meet the requirements of wind-tower welding applications. Created for submerged arc welding on wind-tower bases and door frames, Lincolnweld WTX offers twin and multi-arc AC and DC operations. Additional features include low temperature impact properties, advanced performance when welding circumferential and longitudinal butt and fillet welds and a smooth bead profile. When used with the Lincolnweld L-61 electrode on longitudinal and circumferential seam weld, the Lincolnweld WTX meets the F7A8-EM12K-H8 AWS classification and allows welds to exceed the mechanical property requirements specified for cold-weather wind-tower applications.

Motor Doc's Hot Topics: The Use And Misuse Of Standards In Reliability & Maintenance

Industry standards are produced by professional societies, trade associations and not-for-profit businesses and basically represent best practices developed by experts in their fields. We recognize these practices, or the symbols of the use of such standards, based upon the reputation of the organization. In fact, within the reliability and maintenance (R&M) industry we often quote these documents and say that we follow them. We do not.

Take, for instance, one of the most commonly quoted IEEE Standards used within R&M for electrical testing: IEEE Std 43-2000, “Recommended Practice for Testing Insulation Resistance of Rotating Machinery.” This standard is quoted by instrument companies, service organizations, even our own maintenance departments. Still, I could go into any facility, find someone performing an insulation ground test and get a negative answer to the following questions:

1Are you applying the correct voltage for one minute?

2Are you adjusting the resulting reading for temperature and noting the relative humidity?

3Are you discharging the winding for four times the applied time through a bleeder resistor limiting the discharge current?


4Are you following the other steps involved in 43-2000?

The point is that we think we are following specific industry standards—which are best practices—when we are not. Yet we go blazing forward, developing best practices that will not be followed, based upon our experience with industry best practices. We also can’t use the results to trend potential equipment faults, as present conditions result in non-uniform testing.

To set up a successful environment for pursuing new best practices and trendable results around your operations, you must first nurture the organizational culture by following existing relevant standards—and understanding them to ensure that sales and marketing organizations do not mislead you. MT

Coming Next Time: Misuse of standards by sales and marketing organizations

Among other things, Howard Penrose (AKA “Motor Doc”) is the president of SUCCESS by DESIGN®, a reliability services and publishing company, and the editor-in-chief of the IEEE DEIS Web. A recognized expert, award-winning author and popular speaker, he is involved in standards development for IEEE and other organizations, and he successfully applies reliability and maintenance best practices.

Communications: The OEM Partnership


When maintenance is allowed to interact with the plant and production Original Equipment Manufacturer (OEM), a prosperous relationship for both parties will often ensue. This special relationship results in first-hand information for maintenance to set up its maintenance approach, and valuable operational and design feedback for the OEM.
