What Makes ISC Companies Different?
Put another way, why should someone choose ISC companies as a business partner over another company?
We are unique in offering the combined capabilities and expertise from our three product groups: Bearings & Power Transmission products, Machining & Fabrication and Sensors & Controls. ISC Companies serves a wide range of needs for businesses that build or maintain machinery from providing standard components to the design and manufacture of customized, turnkey solutions. We save our customers procurement costs while increasing productivity, resulting in improved bottom line performance.
Great sounding words, but what does that look like?
To one of our customers it looks like a supplier who was able to solve a problem no one else could. We started with an off the shelf bearing and machining a application specific housing in ISC Companies’ in house machine shop then assembling this unit with a special high temp lubricant. We package and inventory the bearing units and delivering them in kanbans to this customer. Because of our efforts this customer entered a new market segment and added dollars directly to their bottom line.
Another customer turned to us to make a sub assembly using parts they already purchased from us, with parts from other vendors and components we machined and welded in house. The end result was prefabricated sub assemblies that went directly from our inventory to being assembled in machines going down their production line. They saved assembly costs, handling costs, accounting costs and inventory; savings all going right to their bottom line.
Then there was the customer that needed to retrofit a thirty plus year old machine for which they had no prints or manuals. They turned to us to speed up the machine using today’s motor and sensor technology providing the needed mechanical components (both off the shelf and made to order), perform controls wiring and programming and create new drawings and documentation for the machine. We were able to provide all of this for our customer who then had a machine design ready to go into production.
So, let me ask you a question: “What can ISC Companies do for you?”

Product Spotlight: Deublin Rotating Unions
It’s hard to find a manufacturer that doesn’t have at least one or two rotating unions in operation. Some companies such as printers or film extruders may have hundreds. ISC Companies is proud to be a distributor for Deublin rotating unions. Deublin is the leader in virtually every market for rotating unions whether printing, converting, machine tool or wind energy Deublin has a solution for the most demanding applications. The following article presents an overview of the Dublin Company and what makes their product the industry leader.
Since 1945, Deublin has grown from a small garage shop to the world’s largest manufacturer of rotating unions. Today, Deublin’s international headquarters is located in Waukegan, Illinois, with manufacturing facilities, sales offices and warehouses located in 17 countries on four continents. Their worldwide distribution network allows end users all over the world to specify Deublin unions when purchasing equipment made in another country. They’re also manufacturers, so they understand the importance of fast response time to keep your manufacturing process rolling. Whatever your industry, Deublin has a rotating union to meet your requirements—quickly.
Unique Requirements Demand Custom Unions
Rotating unions must accommodate a broad range of materials, viscosities, temperatures, pressures and speeds. That’s why the Deublin product line offers over 500 standard unions, over 3,000 separate models. Even this extensive line cannot meet all the specialized needs required by our customers. That’s why Deublin manufactures an ever-growing line of custom unions to meet individual manufacturers’ particular requirements. In many instances, we can adapt or convert an existing union and offer a cost-effective solution to meet your exact specifications.
A Rotating Union for Every Application
Rotating unions are used in many manufacturing processes to cool, heat or transfer fluid (pneumatic or hydraulic) power. Typical rotating unions feature deep groove ball bearings to support the rotating component against the stationary component, and balanced, precision-engineered mechanical seals to seal the media flow. Deublin rotating unions vary for each application, depending on design, bearing type, construction and material required. In 1989, the Deublin product line was expanded to include steam joints and siphon systems for paper machine dryer cans.
Here are just some of the industries that rely on Deublin for their unique rotating union needs:

Deublin's state-of-the-art manufacturing facilities are strategically located worldwide, and feature the latest CNC technologies including multi-axis/multi-function, robotic interfaces, single point threading and cylindrical grinding. These advanced machining techniques and proprietary processes allow Deublin to achieve the most precise tolerances in the industry, and ensure superior union performance and service life.
Precision
A rotating union must be capable of containing high pressures while rotating at very high speeds. Smooth, easy rotation can only be achieved by exactly mating the seal faces to minimize friction. Precision and tight tolerances are critical in the micro lapping of seal faces. All Deublin seals are micro lapped to an optical flatness within 2 light bands or 0.000023” utilizing proprietary lapping machinery and compounds. This level of precision is essential for dependable leak-proof operation. Housings are machined on multi-axis twin-spindle lathes to obtain the necessary part-to-part precision. Rotors and other parts are turned on automatic bar machines to ensure true-running rotating unions without any wobble. This assures extended service life.
Balanced Mechanical Seal
The greater the pressure on a rotating seal face, the greater the friction, torque and wear on the union. That’s why Deublin rotating unions feature "balanced mechanical seals." With this technology, the thrust load or seal face contact pressure is kept to a minimum regardless of media pressure. This reduces wear, resulting in longer seal life. The spring-loaded seal is keyed so that it cannot rotate or creep, which can cause premature failure in secondary seals, resulting in a leaking union.
Extended Life Sealing
Responding to ever-increasing speeds and pressures, Deublin pioneered Extended Life Sealing (E.L.S.). E.L.S. rotating unions offer outstanding performance under the toughest conditions and can extend service life two to four times, depending on the severity of the application. E.L.S. unions use advanced materials such as tungsten carbide and silicon carbide to provide the best possible seal solution for the application. Where reliability is of prime importance, E.L.S. should be specified to protect against contaminants and resist wear caused by rust, scale, chips and other harmful abrasives.
