Linear drive offers option for automatic shaft cleaning, lubricating
Uhing linear drives are available with a combination shaft scraper/grease fitting option, allowing drive shafts to be cleaned and lubricated while in use.
For automatic cleaning and lubrication of the drive shaft, Uhing linear drives are available with a combination shaft scraper/grease fitting option. The inexpensive addition removes excessive grease, dust and dirt from the shaft while the drive is running and simultaneously assures adequate shaft lubrication. As debris accumulates at either end of the shaft it can be wiped away with a cloth. In most applications the shaft scrapers may be used without the grease fittings to clean the shaft while the drive runs. The grease fitting combination is recommended, however, in heavy usage applications and also when shaft RPMs exceed rated speeds (1000 rpm for Model RG drives; 1500 rpm for Model RS drives).
The shaft scraper is an O-ring made of specially formulated rubber which is mounted in a Delrin brand plastic fitting. One shaft scraper is attached to each of the end bushings on the drive unit. When equipped with the grease fitting, the plastic fitting is made larger to accommodate the addition of a felt wiper ring which wicks oil out of the grease and applies a thin oil film to the shaft as the drive runs. Most standard grease gun nozzles fit the Uhing grease fittings. Note that special, molybdenum disulfide-free grease must be used. If attached in the field, users must also note that the addition of the shaft scraper with or without the grease fitting will slightly reduce the travel distance of the linear drive (for most applications this is less than 1 inch).

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.
