The Powered Uni-Roller® system features a DC gear motor drive and Unist's proven internally-supplied rollers which apply the exact amount of fluid needed to lubricate blanks stock when combined with an SPR-2000™ or SPR-2000-JR™ programmable fluid controller.
On average, a Unist system can reduce stamping fluid consumption by 50% with some customers reporting reductions as high as 90%!
Powered Uni-Roller® for stock Up to 18" (457mm) wide: Compact drive arrangement and single roller design fits in limited spaces. Comes with a 1/17 horsepower DC gear motor that directly drives the lower roller at speeds up to 200 ft. per minute (61 m/minute).
Powered Uni-Roller® for stock wider than 18" (457mm): uses a timing belt to drive the lower roller at speeds up to 145 ft. per minute (44 m/minute). Each system features multiple 12" (305 mm) rollers that are staggered and overlapped. This design controls the lubricant application in zones and allows unit sizes beyond the maximum 58 in. (1422 mm) standard width.
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.
Powered Uni-Rollers™ are available in the following widths: 6" (152 mm), 12" (305mm), 18" (457mm), 23.5" (597mm), 35" (889mm), 46.5" (1,181mm), 58" (1473mm) for stock widths over 58", contact us!
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.
30mm proximity sensor option is used to provide an input signal to an SPR-2000™ or SPR-2000JR ™ programmable fluid controller.
AC variable frequency drive option is available for automated applications and allows many advanced motor control functions.
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.

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.
Prime button for easy priming of the Mini-Roller's™ roller covers.
Visual and audio alarm notification plus an alarm relay output for integration.
Access code prevents tampering by unauthorized personnel.
