Extend the lifespan of dies, minimize scrap, and enhance the quality of parts through effective stock lubrication. Utilizing a powered roller lubricator, a single operator can efficiently apply a uniform layer of lubrication to both sides of the stock, ensuring optimal performance.
- Reduce labor
- Mobile/portable design
- Improve cycle times
- Reduce fluid consumption
Streamline multiple press line operations with a single Powered Roller Cart™. Effortlessly maneuver between press lines, and switch fluid settings on the go. Stock sensors ensure lubrication application only when blanks are detected. Carts include a SmartFlow fluid controller, powered roller lubricator, and fluid supply tank.
Optimize profits and cycle times with advanced fluid controls. With precise output control, job storage, and an easy-to-use interface, SmartFlow® gives you complete command over your fluid application. Experience enhanced efficiency through the ability to save and swiftly recall job settings, enabling rapid press line changeover. Simplify the configuration, control, monitoring, Auto feed & return and tracking processes with the user-friendly SmartFlow® controller.
Easily create Jobs
Effortlessly create and save jobs for each operation. Just choose your desired job, reducing new job setup time to a matter of seconds.
Fluid tracking
SmartFlow takes the guesswork out of tracking fluid consumption. With an optional flow meter, you’ll know exactly how much fluid your process is consuming and you’ll work smarter knowing your lubricant cost per part.
Powered Roller Cart™ 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 Powered Roller Cart™ 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.
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 Powered Roller Cart™ 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!
Powered Roller Cart™ delivers smooth and consistent lubrication.
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 Powered Roller Cart™ 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.
Carts are built to match the width of the powered roller lubricator: cart dimensions
