Force Balancing Mechanical Seals

Pumps are one of the largest users of mechanical seals. As the name suggests, mechanical seals are contact-type seals, differentiated from aerodynamic or labyrinth non-contact seals. Mechanical seals are also characterized as balanced or unbalanced. This refers to...

Axis Of Rotation

In the history of machine tools, spindles have been very good relative to other bearings and structures on the machine. So Quality professionals have developed a cache of tools – like ball bars, grid encoders and displacement lasers – to help them characterize and...

Gas Bearing Lubrication In Turbomachinery

Gas bearing lubrication in Turbo equipment has been making slow but steady progress. Almost all fluid film lubrication applications in Turbo equipment use hydrodynamic (oil) or aerodynamic (gas) bearing technology. Hydrodynamic lubrication uses the relative shear...

Balancing Act

Gas bearings are not a new technology, but that doesn’t mean they can’t be used in a new manner. Drew Devitt, founder and chief technology officer of New Way Air Bearings, hopes that’s the case with his company’s Bently balance bearings, which...

Get Your Bearings Straight

Ask most people about innovation in bearings and they will mention magnetic bearings. Certainly, they deserve the spotlight. It seems that every turbine OEM and major bearing supplier has been eager to augment its arsenal with mag bearings. Examples include...
