    uni roller s2
    Blank coating solution

    The Uni-Roller® S2 Powered is the ultimate solution in blank stock lubrication. Combined with an SPR-2000 or SPR-2000 JR programmable fluid controller, the S2 Powered will apply the correct amount of fluid for your application and do it consistently from one blank to the next.

    • Reduce lubricant consumption by 50% or more
    • Cleaner floors & work area
    • Quick-change rollers for easy maintenance

    Uni-Roller® S2 Powered applications:

    • Punching
    • Stamping
    • Fine blanking
    • Deep drawing
    • Application of rust preventives and other protective coatings

    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® S2 Powered lubricator uses 50 to 90% less lubricant for stock lubrication. 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 internally-supplied difference

    The internally-supplied rollers are essential to precisely applying the fluid. Inside each of the rollers is a dispenser tube with small holes placed along its length. Fluid is injected into the dispenser tubes from the fluid controller and dispensed across the inside of the rollers.

    internally fed

    The lubricant is transferred to the stock through durable polyester felt or polyurethane foam roller covers. These cover materials apply the lubricant smoothly and evenly across both the top and bottom of the stock.

    The Uni-Roller® S2 Powered applies the exact amount of lubricant required. This eliminates the mess and waste associated with in-die spray systems and externally lubricated roller systems. The result is not only a cleaner shop, but also significant savings from decreased fluid waste, improved die life, better part quality and increased machine up-time. Many customers have reported savings resulting in a return on investment of less than six months!


    The brushed stainless steel guards protect the rollers and guide material when loading coil stock or feeding blanks. With the guards removed for better access, a roller can be changed in about a minute using a single wrench. The Uni-Roller® S2 Powered is built to handle any manufacturing environment without sacrificing ease of maintenance.

    Built to fit your application

    A single roller set is used for widths of 18” [457.2 mm] or less where the lower roller is directly driven. For blanks over 18” [457.2 mm] wide, multiple 12” [304.8 mm] wide roller sets are staggered and overlapped. Each lower roller is driven by a heavy-duty chain from a central shaft.

    Take control with the SPR-2000

    The SPR-2000™ alerts you to issues before they become expensive problems that interrupt or stop your production lines. With the SPR-2000™ 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 SPR-2000™ features an intuitive, easy-to-use interface as well as an access code to prevent unauthorized tampering or changes in fluid settings.

    small spr
    • Monitors critical parameters
    • Controls up to 22 outputs
    • Stores up to 250 setups

    Prime button for easy priming of the felt application pads.

    Visual and audio alarm notification plus an alarm relay output for integration.

    Access code prevents tampering by unauthorized personnel.
