Powered Uni-Roller™  Intelligent blank coating solution

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.
  • Precision lubrication for blank stock
  • Save 50% on lubrication costs
  • Eliminate mess
  • Precise control with SPR-2000


  • Apply fluid to one or both sides of stock
  • Neat application – No fluid mess!
  • Reduces fluid usage – Saves money!
  • Apply fluid to one or both sides of stock

Powered Uni-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%!


Available in 2 configurations

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.

Powered Uni-Roller® applications:

  • Punching
  • Stamping
  • Fine blanking
  • Deep Drawing
  • Application of rust preventives & 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® 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
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!


Available roller covers:

roller cover materials

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.

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.

SPR-2000™ 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.
