Servo valves

D634-P direct drive, servo-proportional valve offers the highest flow for applications where speed is required while providing safety, energy savings, and responsiveness. The valve has integrated electronics and is available in 6, 10, and 15-gpm flow versions with a Dp of 75 psi per land. At high pressure drop, the valve holds its maximum flow area nearly constant.

Hose couplings

Swing-Couplings eliminate the common hazards associated with connecting and disconnecting pneumatic couplings and quick disconnects. They eliminate the hose whiplash effect by requiring the user to first pull back a locking collar, then swing a plug into position for release. This two-stage operation eliminates whip and ensures a safe disconnect.

Bearing substitute

DryLin R bearings are maintenance-free and dry-running, making them an ideal substitute for traditional ball bearings, especially in harsh, debris infested, or water-based environments. By reducing the clearance between the bearing liner and shaft by 50%, life expectancy is more than doubled.

Versatile gearboxes

Z-Series spiral-bevel gearboxes serve as speed reducers or increasers while delivering an efficiency of 96% to 99%. Available in seven sizes and six model types, the units are constructed of case hardened and lapped alloy steel, spiral-bevel gears, ensuring low noise, reduced backlash, and less transmission error. Two and three-shaft models have capacities from 2 hp to 540 hp.

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.
