Inpro/Seal reports record sales. Attibutes it to an installed product/installation base fast approaching two million; direct customer feedback; a vigorous R & D program; an engineering data bank of over 58,000 designs that assures same day delivery at no extra charge; and an “educate and inform” marketing approach that has lead to a dramatic increase in acceptance for for the Inpro/Seal brand.

Inpro/Seal Company, the Rock Island, IL, based manufacturer of bearing isolators reports record sales for calendar year 2005. In addition, the company reports that advance orders, shipments and projections are far ahead of last year.


Though a number of factors come into play, the firm attributes much of this extraordinary success to: an installed product/installation base fast approaching two million; direct customer feedback; a vigorous R & D program; an engineering data bank of over 58,000 designs that assures same day delivery at no extra charge; and an “educate and inform” marketing approach that has lead to a dramatic increase in acceptance for for the Inpro/Seal brand.

Product Enhancements From A Very Active R & D Program

Their R & D program, conducted from the worlds largest campus devoted to bearing isolation technology, continues to develop new products and enhancements to existing products that increase plant productivity with measurable bottom line results. To illustrate how active their R & D is, these are a few examples announced during 2005:

  •     MGS Motor Grounding Seal - a revolutionary new product that stops the damaging effects caused by destructive residual shaft currents on AC motors. Specifically developed for VFD controlled motor applications, the MGS prevents pitting, fluting, fusion craters and eliminates catastrophic motor failure while permanently protecting bearings from contamination.
  •     Articulating Powder Seal - Inpro/Seal now offers two sealing solutions the Air Mizer™-PS and the Articulating Air Mizer™- PS™ that provide a positive seal in applications were dry particulates, powders and bulk solids are handled, processed, packaged and stored.
  •     Oil Mist – significant enhancements and improvements were made to their tried and proven oil mist bearing isolator, renaming it the OM 32 Oil Mist Bearing Isolator Series. The OM 32 is the only known method that solves housekeeping issues to contain and keep stray most from entering the environment.
  •     VBXX-MT™ Series Bearing Isolators – offers machine tool users protection from coolant, chips, humidity and heat, that can cause spindle malfunction and expensive, unscheduled downtime. The highest performance is assured with a reverse interface that avoids direct impingement of coolant and chips.
  •     Plus –the only product that protects rolling element bearings on paper machines from the wet end to the dry end; IEEE-841 motors that use bearing isolators as part of their specification and the standard for bearing protection; ad hoc designs for gear boxes, axial shaft movement and one of a kind projects and more.

Important To Educate And Inform

According to David C. Orlowski, President and founder of Inpro/Seal Company and considered by many as the “father” of bearing isolation technology, “More and more lip seal users at the plant maintenance level (and above) have learned that there are misconceptions when it comes to sealing devices and that contact seals are not the only option when it comes to protecting bearings.”

Orlowski continued, “Over the last couple of years, we have conducted extensive research into the use of bearing protection on a market-by-market, application by application basis and found that people wanted to know more about bearing isolators. As a direct result, in 2005 we published a brochure entitled Introduction To Bearing Isolators……A Short Lesson In Bearing Isolation which has become the most successful literature we have ever developed.”

Maintenance People Are Fast Becoming Converts To Bearing Isolators

Orlowski went on to say that, “When lip seals were first introduced more than 70 years ago, they were the only kind of sealing device available. Convenient and inexpensive, they went on to capture a 99% market share. Today, lip seal manufacturers state that at best, they have a median, average life cycle of 1,844 hours or 77 days of operation, though some may survive up to 3,000 hours. This means that, in the real world, lip seals are not meant for heavy duty, industrial applications where rotating equipment is designed to run, uninterrupted for five years. Once end users find out that bearing isolators provide levels of protection unavailable in any kind of bearing protection device with bottom line implications, they get fed up with the 70-year-old technology they had been using and quickly become an Inpro/Seal convert. Another in-demand brochure, Are Lip Seals Obsolete?, provides more in-depth information.

Energy Aspects

Orlowski concluded, “When engaged with a rotating shaft, each contact seal, (lip seal and face seal) consumes, on average, 147 watts of power while operating. To show how significant this is, a plant with 600 operating pumps, can run up annual costs in excess of $117,000 for energy to drive the lip seals. Add to that the costs associated with downtime and you can again see why more and more end users are switching to Inpro/Seal bearing isolators.”

More On Motors

Since the Federal mandate for the use of premium efficiency motors (EPAct) was put into effect, more and more end users have opted for a significantly more reliable IEEE-841 Motor, developed by the Institute of Electrical Engineers. The IEEE-841 standard was written to establish additional guidelines to improve motor reliability, efficiency and performance. A very important feature of these motors is bearing protection. Realizing that the most economical motor is one that runs reliably and the avoidance of a single motor failure more than pays for the entire motor, the IEEE-841 Motor has become an industry standard.

VBXX-D, The Next Generation

When Inpro/Seal introduced their original VBX™ series fifteen years ago, it provided end users with a way to eliminate the root cause of premature equipment failure – contamination entering the bearing environment – while increasing productivity and reliability in the process. Since then, hundreds of thousands have been installed in plants around the world. Today, the VBXX-D the next generation in bearing isolators has taken hold offering the latest and best non-contacting labyrinth sealing technology to improve plant uptime and reliability with an ROI that more than doubles previous results with levels of bearing protection previously unavailable.

Industry Leading Internet Support

Inpro/Seal has also invested heavily into web sites dedicated to the education of bearing isolation technology with much downloadable information. When an end user visits or they will find a wealth of information related to both Inpro/Seal and bearing protection, including: specific applications, case histories, data sheets, facts and questions, specifications and more. Interactive spreadsheets include a Cost Justification Worksheet and Contact Seal Energy Consumption Calculator. Simply to complete, an end user merely fills in the blank to calculate ROI and benchmark repair costs.

About Inpro/Seal

Inpro/Seal Company is the originator and the world’s number one manufacturer of bearing isolators, used to protect motor and pump bearings, machine tool spindles, turbines, fans, gear boxes, paper machine rolls and many other types of rotating equipment.
