Inpro/Seal, a manufacturer of bearing isolators, has revised its website, located at www.inpro-seal.com, putting the emphasis on education and information. Dedicated solely to bearing protection technology, the site incorporates illustrations, charts, diagrams, installations, product photography, documentation, product literature, feature articles, FAQs, guarantees and more to educate, inform and simplify the bearing isolator selection process.
The site includes information on the evolution of the bearing isolator, including: how and why it was invented; how it works; how and why contact seals fail in a short period of time; how to eliminate catastrophic failure; how to reduce power consumption in rotating equipment; costs; maintenance; and designs and configurations.
It is a useful tool for anyone involved in the management, maintenance, repair and operations of motors, machine tool spindles, turbines, fans, gearboxes, paper machine rolls, pumps, conveyors, shafts, etc., used in industrial/process plants. Additional applications include the sealing, handling, processing, packing and storage of dry particulates, powders and bulk solids.
The bearing isolator is a non-contact, non-wearing, permanent bearing protection device. It has a rotor and a stator, and the two are unitized so that they will not separate from one another while in use. Typically, the rotor turns with the rotating shaft, while the stator is pressed into a bearing housing. The two components interact to keep contamination out of, and the lubricant in, the bearing enclosure.
While a lip seal or contact seal operates with contact, the bearing isolator makes no contact, never wears out and can be used over and over for many years. Contact seals, on the other hand, have a 100% failure rate.
Of the 2-1/2 million bearing isolators installed, most of them continue to be in operation in process plants worldwide, where end users report reduced operating costs with increased productivity and reliability. Protected bearings have proven to run 150,000 hours (17 years) or more, eliminating the need for constant maintenance and repair. Documented cases show that a plant can more than double the mean time between failure (MTBF) and reduce maintenance costs by at least half, with users reporting an extremely high ROI. Inpro/Seal
