  1. Freudenberg Announces New Seals and Materials for the Aerospace Industry

    Freudenberg Sealing Technologies introduced several new material and sealing innovations at the 2019 International Paris Air Show.

    These new products are designed to help aerospace customers address ever increasing safety and performance requirements in the industry.

    During the June 17-23 event in Paris, Freudenberg showcased a new high temperature, fireproof material; an Omegat OMS-CS cap seal; and new ethylene propylene diene monomer (EPDM) and a fluoroelastomer (FKM) developmental material.

    “Our aerospace customers strive continuously to be faster, safer and more efficient, which in turn requires us to innovate to help them reach those goals – a challenge we enthusiastically embrace,” said Vinay Nilkanth, vice president, Global Mobility Sector, Freudenberg Sealing Technologies. “The launch of several new products aimed at improved performance underscores Freudenberg’s commitment

  2. Vesconite Bearings - Three Dakar Rallies With No Grease

    The Dakar Rally - What is it?

    The Dakar Rally (or simply "The Dakar") is an annual rally raid organized by the Amaury Sport Organisation. Since its inception in 1977, most races took place from Paris, France, to Dakar, Senegal. But due to security threats in Mauritania, which led to the cancellation of the 2008 rally, races since 2009 have been held in South America. The race is open to both amateur and professional entries, of which amateurs typically comprise of eighty percent of all participants.

    The race is an off-road endurance event. The terrain that the competitors traverse is much tougher than that used in conventional rallying, and the vehicles used are true off-road vehicles rather than modified on-road vehicles. Most of the competitive special sections are off-road, crossing dunes, mud, camel grass, rocks, and erg among others. The distances of each stage covered vary from short distances up to 800–900 kilometres (500–560 mi) per day.

  3. EagleBurgmann Shaft Seals in Waste Paper Treatment

    Waste paper treatment is of great significance in the paper industry. The collected and sorted waste paper is fiberized in pulpers using large amounts of water with the addition of chemicals and is sorted into slightly and heavily contaminated fractions.

    In the de-inking process, the printing ink is removed by means of chemicals and mechanical forces and is skimmed as foam from the surface in the subsequent flotation.

    The risk of dry running for the mechanical seal is especially great for the machines used in the flotation process. The seals in the coarse screening are subjected to intense stress due to the contaminations inclined to plaiting. Know-how and experience in the selection of seals and materials are requirements in order to ensure optimal and trouble-free operation.

    The shafts of bleaching agent pumps, MC pumps, dispersers, slurry pumps, sorters, pulpers

  4. A Closer Look at Parco's 4200 Nitrile Seals

    Nitrile (NBR) is a copolymer of butadiene and acrylonitrile. Due to its excellent resistance to petroleum products and its ability to be compounded for service over a temperature range of -30°F to +250°F, Nitrile /NBR is the most widely used elastomer in the seal industry today. NBR o-rings are very versatile, inexpensive material which contributes to its wide array of applications.

    Let's start with the 4200-70 General-Purpose Nitrile Seal. What differentiates this material?

    1. Excellent Physical Properties

    Parco’s 4200-70 70-durometer nitrile O-rings have excellent physical properties. For nearly 40 years, 4200-70 O-rings have been used in a wide variety of  applications with great results. So when you specify 4200-70, rest assured that you’ve made the right choice.

    2. Excellent Resistance to Compression Set

    To perform properly, seals must resist taking a set from compression after being installed. When a seal takes

  5. How Would you Handle Corrosion in your Steel Mill?

    Addressing New Issues

    Steel mill operators don’t like to have downtime problems, in fact they can’t afford to.  They want to run as much as possible, and as efficiently as possible.  Production equals dollars.  As problems pop up that cause unplanned downtime or upset production (and subsequently get addressed) over the years, they’ve driven the industry to continue to change and evolve as a whole.  So the mills of today don’t have the same issues that mills did in the past.  You can’t as easily say “Hey, we saw this exact same problem up the street on their furnace!” the way you may have been able to 50 years ago.

    That doesn’t mean that mills still don’t run into issues, they just tend to be a bit more personalized. And when you have a unique issue, you tend to get a unique solution.  A mill will do its best to solve its own problems, yet each mill has their own idiosyncrasies.
