1 Minimum Design Speed Considerations for Sleevoil Bearings for Industrial Fan Applications (September 2016)

Slow speed operation of fan systems within the air handling industry is generally performed due to two reasons: a coast down operation is required for hot (induced draft) fans to cool down before shutdown (often by using a turning gear), and operational efficiency improvements can be achieved during non-peak periods by slow speed operation using a VFD. In either case, when these fans are supported by hydrodynamic bearings, it is the oil film thickness developed from the bearing-shaft interaction that limits the minimum speed that can be maintained without causing premature wear and bearing failure. This paper will present a brief overview of lubrication theory and critical design parameters to achieve slow speed operation.

Heaven help Mr. Deane were he around today. In our non-stop world of transportation & transport technology, for at least the past decade it is without question the electric car that has drawn most of the attention

6 Guidelines for Bearing Seals (October 2016)

Equipment downtime and reduced component life are a few of the consequences — and potential costs — of using the wrong seals on many types of industrial equipment including pump bearing frames, electric motors, fans, pillow blocks, gearboxes and more. However, if correctly specified and installed, seals provide effective barriers that both retain lubricants as well as protect against water, corrosion, debris and other contaminants.

7 Turning Science Fiction Into Fact (August 2008)

Fans of Arthur C. Clarke may remember a concept in his 1979 novel, The Fountains of Paradise, of an orbital elevator used to raise payloads from the ground to a satellite as a more cost-effective means of transporting material to outer space.
