Uni-Roller® S2 HG

Product Info

Lubrication for thick stock

The Uni-Roller® S2 HG delivers the same smooth and consistent fluid application the industry has come to expect from Unist, and adds an articulating chassis. The upper rollers opens a full 6” [152 mm] to avoid deformities in the head or tail of coil stock, making loading easier and preventing damage to the lubricator itself.

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

Uni-Roller® S2 HG 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® lubricator uses 50 to 90% less lubricant for coil 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.

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 HG is built to handle any manufacturing environment without sacrificing ease of maintenance.


Single roller unit shown above. Lubricators with multiple roller sets have guards on both entry and exit sides.

Built to fit your application

The Uni-Roller® S2 is modular in design. A single roller set is used for widths of 18” [457.2 mm] or less. For stock over 18” [457.2 mm] wide, multiple 12” [304.8 mm] wide roller sets are staggered and overlapped. Standard sizes are available to accommodate common stock widths, with custom sizes available on request.

Multiple rollers (coverage over 18”) [457.2 mm]
12” [304.8 mm] 19” [482.6 mm] 25.18” [639.6 mm]
18” [457 mm] 25” [635 mm] 31.18” [792 mm]
23.5” [597 mm] 31” [784.4 mm] 37.18” [944.4 mm]
35” [889 mm] 43” [1092.2 mm] 49.18” [1249.2 mm]
46.5” [1181.1 mm] 55” [1397 mm] 61.18” [1554 mm]

69.5” [1765.3 mm] 79” [2006.6 mm] 85.18” [2163.6 mm]

*On units with double air cylinders add 1.4” [35.56 mm] to the pass line and overall height

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.

  • Monitors critical parameters
  • Controls up to 22 outputs
  • Stores up to 250 setups
Easy to use touch screen interface.
