Applies the precise amount of continuous lubrication to 1 or both sides of your coil stock at line speeds greater than 100 ft. per minute (30.5 m/minute). Unique internally-fed design is an unsurpassed solution for metal forming applications when combined with a SPR-2000™ or SPR-2000-JR™ programmable fluid controller.
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.
Offers almost limitless sizes over the standard 69.50 in. (1765 mm) width. Unique modular design staggers and overlaps multiple 12 in. (305 mm) wide roller sets for widths over 18 in. (457 mm).
|Pneumatic roller pressure models available for stock widths from 3 to 69.50 in. (76 mm-1765 mm).|
|Compact spring latch roller pressure models available for stock widths from 3 to 12 in. (76 mm-305 mm).|
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.
The Uni-Roller® HG option adds an articulating chassis to our Uni-Roller® Type S system. The upper rollers can be raised or lowered to accommodate deformities in the head or tail of coil stock. This prevents damage to the lubricator and facilitates easier loading.
Polyester felt (standard)
Extremely durable and compatible with a broad range of fluids
Polyurethane foam cover (optional)
For use with vanishing oils and with thin stock which is narrow compared to overall roller width. Limited fluid compatibility, please contact Unist before selecting this option.
Stock guides* facilitate easy loading of the coil into the Uni-Roller® Type S.
Double cylinders* are required for stock thicknesses over .25 in. (6.3mm). Allows rollers to float w/stock.
Proximity sensor provides input to an SPR-2000™ based on roller rotation. Use when an intermittent press signal is not available.
*not available on spring latch units

The SPR-2000™ coil lubrication system 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.
