Shaft grounding ring
This bearing isolator shaft grounding ring protects bearings in VFD-driven IEEE 841 and other severe-duty motors.
The AEGIS 841 SGR bearing isolator shaft grounding ringprotects severe-duty motor bearings from harmful VFD-induced shaft currentswith a proven shaft grounding ring, and from contaminants with an IP56non-contact seal. IEEE Standard 841-2001 calls for protection against bearingdamage by VFD-induced currents in addition to bearing seals.
Traditional bearing seals provide only half the protection
needed by VFD-controlled IEEE 841 and other severe-duty motors. Designed for
long-term total bearing protection, the AEGIS 841 SGR combines a proven shaft grounding
ring (in which conductive microfibers completely surround the motor shaft)and
a non-contact IP56 bearing isolator that withstands dust and powerful jetting
water (providing even greater protection against contaminants than is required
by IEEE Standard 841). The AEGIS shaft grounding ring has been proven in
hundreds of thousands of installations worldwide to protect bearings from
harmful currents and extend motor life. By diverting VFD-induced shaft currents
around bearings safely to ground, the ring protects them from electrical damage
known as bearing fluting that can lead to noise and vibration and result in
motor failure. The AEGIS 841 SGR's bearing isolator features an Anti-Clog
slinger drain system to prevent dirt and debris from plugging the drain and
compromising performance. The slinger's unique design chops and ejects foreign
matter, keeping the drain running free.

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.
