Tough hose bends easily
472TC hose is for high-impulse applications requiring superior flexibility. It features a one-half SAE 100R12 minimum bend radius and exceeds SAE 100R16 specifications, meaning installation is easy and less hose is used. With a 15% to 35% higher working pressure than SAE 100Rs2 hose, the two-wire braid hose has an oil-resistant, synthetic, high Nitrile rubber tube that handles a variety of fluids.

Hot/cold alignment fixture
OL2R fixtures are easy to use and solve a major problem by measuring the true dynamic movement of rotating machinery as it goes from offline (cold) to operating (hot) conditions. This measurement provides the information to intentionally misalign machinery when aligning, ensuring they will grow into an aligned condition when running.

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
