The Uni-Roller® S2 Powered lubricator by UNIST is designed to apply an even layer of lubricant to both sides of metal blanks before stamping operations. Its powered rollers also feed the material when the machine does not have another feeding system.
Equipped with a photoelectric sensor that detects passing blanks, the Uni-Roller® S2 Powered provides precise control over lubricant application. Its internally-fed rollers ensure consistent lubrication while reducing fluid consumption, lubricant waste, and maintenance requirements.
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.
Ensures even and consistent coating on one or both sides of stock
Roller cover replacements take minutes to swap in
DC gear motor for powered blank feed
Photo sensors detects blanks for fluid actuation
Designed to withstand the harshest industrial conditions
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 Powered is built to handle any manufacturing environment without sacrificing ease of maintenance.
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.
