Mini-Roller Continuous Lubrication for Coil Stock by UNIST
The UNIST Mini-Roller™ lubricator is designed to apply a uniform coating of lubricant to thin and narrow coil stock. Ideal for high-speed presses, small press windows, and applications such as punching, stamping, four-slide forming, and roll forming.
With its internally-fed rollers, the Mini-Roller™ provides precise and consistent lubrication on one or both sides of the stock. Available in horizontal and vertical configurations, it helps reduce lubricant consumption, minimize fluid waste, and maintain a cleaner working environment.
Intelligent Stock Coating Solution
The Mini-Roller™ applies the correct amount of fluid for your small press window and high-speed, short feed length applications when combined with a SmartFlow® programmable fluid controller. This 1 to 6 in. wide (25 mm to 152.4 mm) unit consistently applies the correct amount of fluid and lets you start saving now.
Advantages of the Mini-Roller
- Reduce fluid consumption by 50–90%
- <1 year average ROI
- Smooth and consistent coating on one or both sides of the stock
- 30% longer between die maintenance
- Decrease scrap rates
- Eliminate messy floors

An Ingenious Design
The Mini-Roller™ is available in both horizontal and vertical configurations. Each uses internally-supplied rollers that are essential to precisely applying the fluid.
The Horizontal model uses a fluid controller to inject lubricant into a dispenser tube inside the roller. Small holes in the tube evenly distribute the lubricant along the length of the roller.
The horizontal configuration has a dispenser tube with small holes placed along its length inside each of the rollers. Fluid is injected into the dispenser tubes from the fluid controller and dispensed across the inside of the rollers.
The Vertical model uses a baffle positioned inside each of the rollers near the top. Every time the fluid controller injects lubricant into the dispenser tube, the fluid spreads across the baffle and is redirected to the outside of the roller. Gravity pulls fluid down the length of the cover.
The vertical configuration includes a baffle positioned inside each of the rollers near the top. Every time fluid is injected into the dispenser tube from the fluid controller, it spreads across the baffle where it is then redirected to the outside of the roller. The wicking action of the roller cover material then draws the fluid along the length of the roller.
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 sides of the stock.
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!
