    Intelligent stock coating solution

    The Mini-Roller applies the correct amount of fluid for your small press window and high-speed, short feed length applications when combined with a SmartFlow programmable fluid controller. This 1 to 6 in. wide (25 mm to 152.4 mm) unit consistently applies the correct amount of fluid and lets you start saving now.

    save 50 percent

    Mini-Roller reduces fluid usage and saves money

    On average, a Unist system can reduce stamping fluid consumption by 50% with some customers reporting reductions as high as 90%!




    2 configurations

    Horizontal model uses a fluid controller to inject lubricant into a dispenser tube inside the roller. Small holes in the tube evenly distribute the lubricant along the length of the roller.

    Vertical model uses a baffle positioned inside each of the rollers near the top. Every time the fluid controller injects lubricant into the dispenser tube, the fluid spreads across the baffle and is redirected to the outside of the roller. Gravity pulls fluid down the length of the cover.

    Mini-Roller applications:

    • Small press windows
    • High-speed, short-feed lengths
    • Thin stock
    • Punching
    • Stamping
    • Roll forming
    • Four slide
    • Many other metal forming applications

    Delivers return on investment in less than 6 months

    That's what many of our customers report. By applying the proper amount of fluid, the Uni-Roller® lubricator 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.





    Available widths

    Both vertical and horizontal Mini-Rollers are available in 1" (25mm), 2" (51mm), 3" (76mm), 4" (102mm), and 6" (152.4mm) widths

    Available roller covers:

    roller cover materials

    Polyester felt (standard)
    Extremely durable and compatible with a broad range of fluids

    Polyurethane foam cover (optional)
    For use with vanishing oils and with thin stock which is narrow compared to overall roller width. Limited fluid compatibility, please contact Unist before selecting this option.





    The Internally-fed difference

    All Uni-Roller systems feature a unique, internally-fed roller design. This is the key to uniform and efficient fluid application. As illustrated, inside each of the rollers there is a dispenser tube with several small holes spaced along its length. Every time the fluid is injected into the dispenser tubes from the fluid controller, it is dispensed evenly across the inside of the roller through these holes.


    The lubricant is then transferred to the stock through a durable polyester felt or polyurethane foam roller cover. These cover materials apply the lubricant smoothly and evenly across both the top and bottom of the stock. As the system continues to cycle, additional lubricant is injected into the rollers to replenish the lubricant applied to the stock. The advantage of this system is consistent application of the exact amount of lubricant required for any particular operation.

    Uni-Roller® systems deliver smooth and consistent lubrication.




    Take control with the SmartFlow

    The SmartFlow alerts you to issues before they become expensive problems that interrupt or stop your production lines. With the SmartFlow you'll know immediately if the fluid supply runs low, if fluid pressure varies, or if flow to the applicator is interrupted (Level, pressure, and flow sensors required). The SmartFlow features an intuitive, easy-to-use interface as well as an access code to prevent unauthorized tampering or changes in fluid settings.
