1 How to Prevent Pulley Slippage (February 2017)

I'm not able to get a good connection between the pulley and shaft in my drive assembly. Could you explain the various ways of connecting a pulley to a shaft to prevent the pulley from slipping?

2 The Science of Radial Shaft Seals (April 2017)

SKF Product Investigation Center Troubleshoots Critical Rotating Equipment Applications with Analysis, Research and Testing Procedures.

3 Understanding the Dynamic Influences of Gear Oils and Radial Shaft Seals (February 2018)

Sustainability is becoming one of the most important aspects within the power transmission business. Users demand low-maintenance drive systems with as little disruption as possible, and expect lifetimes of more than 10,000 hours. Approximately 40 percent of long-term gearbox leakages can be traced back to poor interaction between the radial shaft seal (RSS) and the lubricant. Thus, it becomes essential to analyze the tribological system as a whole, which includes the gear oil, seal grease (if required), elastomer material and design, and the shaft.

4 Reducing Food Processing Plant Energy Costs (February 2016)

U.S. manufacturers, such as food processors, face an unprecedented competitive environment and must look for ways to be profitable without negatively affecting the quality of finished products.

5 Bearing Protection Needed if Inverter-Duty Motors Are to Live up to their Name (August 2012)

All major manufacturers of 3-phase AC induction motors offer "inverter-duty" or "inverter-ready” models, but while these motors have inverter-rated insulation to protect the windings, the bearings--their most vulnerable parts--are too often ignored.

6 Torque Arm Design Considerations for Shaft-Mounted Speed Reducers (April 2008)

Most manufacturers of shaft-mounted speed reducers offer torque arms for their products. However, in some situations, a machine designer may be required to design his own.

7 Sky Science (April 2012)

S.S. White Provides Twisting, Turning Power Transmission with Flexible Shafts

8 University Improves Sustainability of HVAC Motors in Platinum LEED Building (April 2012)

A new preventive maintenance program at a leading New England Ivy League university demonstrates how the push for more sustainable "green" building management has led to a growing awareness of a chronic, widespread problem with HVAC motors—electrical bearing damage and failure.

9 Flexible Options with Flexible Shafts (August 2013)

You need to transmit a rotary motion where no straight line is possible. Or, you need to allow for some uncontrollable misalignment. How about transmission taking place between moving components? What if you need to control something in hazardous locations where you cannot directly handle the application, such as high-temperature environments, under hazardous conditions or in clean room applications? Functionally designed flexible shafts can meet all these challenges.
