A look at the IMTS 2012 show from a power transmission component perspective.

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.

This special product news section takes a look at the latest in motion control products.

Nowadays, you can find scientists and engineers creating micro-robotic creatures for a slew of fascinating research projects.

Suggesting a bicycle is environmentally friendly is stating the obvious. But the Copenhagen Wheel, unveiled at the 2009 COP15 United Nations Climate Conference, is taking green technology and cycling in a new direction.

The Bearing Specialists Association explains the role of bearings in ensuring the efficient operation of machinery.

In the history of machine tools, spindles have been very good relative to other bearings and structures on the machine. So quality professionals have developed a cache of tools—-ball bars, grid encoders displacement lasers, etc.—-to help them characterize and understand the geometry of the structural loop. But as machine tools have improved in their capability and precision, and the demands of part-geometry and surface finish have become more critical, errors in spindles have become a larger percentage of the total error.

The recent trend toward using segmented laminations as a means to increase slot fill and facilitate automated fabrication of electric machines comes with a penalty of increased core loss at the segment joints.

Th e ISO defi nition of a full- complement bearing states that the bearing does not have a cage. When that defi nition was written, it was not technically possible to have a full-complement bearing with a cage. But SKF’s new high-capacity cylindrical roller bearing combines the load-carrying capacity of a fullcomplement bearing with the benefi ts of a bearing with a cage (Fig.1).
