2.1 About Uni-Roller® Systems

It depends on the lubricant in some cases, but a general guideline is that Uni-Roller® type C units can run up to 100 ft/min and Uni-Roller® type S units can run up to 500 ft/min.

Parts are in stock and in most cases can be sent out the next day.

Usually 9 months, although it depends on the application and the condition of the metal (burrs on the edges will damage the covers and shorten their lifespan)


Usually 2-3 weeks

No, there is no battery in the panel. However, all of the systems data is stored in an EEPROM so there should be no loss of data in the event of a power failure.

Flow sensors can be used to monitor the flow from a valve each time it is actuated. They work by watching for flow every time a valve is actuated and then transmitting a signal to the system . Once the system has confirmed flow, it doesn’t monitor the flow sensor again until the next valve cycle. As a result, if the duration is quite long, and flow is confirmed within the first .5 second, the system would not detect it if the flow stopped after that time until the next cycle. Another limitation is that the sensors can not differentiate between the flow of fluid or air. As a result, if the fluid reservoir runs dry so air is flowing through the valve instead of fluid, it would not create an alarm. In this case, a low level switch in the fluid reservoir would detect the problem. One other limitation is that since a flow sensor requires some time to sense flow, it is usually not possible to detect flow for a duration of less than about 250 milliseconds.

Our Uni-Roller® systems deliver return on investment in less than six months. That’s what many of our customers report. By applying the proper amount of fluid, Uni-Roller® uses 50 to 90% less lubricant. Plus it decreases the mess, the parts cleaning, fluid recycling and costs associated with in-die spray systems, rag technology and externally lubricated rollers.

The correct rollers for your application depend on your fluid of choice.  In most cases, our polyester felt roller covers will offer the best performance.  For vanishing oils and for thin stock that is narrower than the overall width of the roller, our polyurethane foam roller covers may be a better choice.  Viscosity of the fluid plays a small role but there are other factors to consider.  Contact Unist with details on your specific application and fluid type and we’ll be happy to make a recommendation!
