4″ Heavy Duty Steel Slip Roller

4″ Heavy Duty Steel Slip Roller —-This is our largest, most capable unit with 4″ diameter rollers.  We recently upgraded it to be quick-change position.  Instead of 8 holes in each side, it has a slot system.

Capabilities:

2″ wide of 1/2″ thick HR steel bar

6″ wide of 3/8 thick steel bar / plate

24″ wide of 1/4″ thick steel plate

36″ wide of 3/16″ thick steel plate

48″ wide of 1/8″ thick steel sheet

ARC square tubing – 1x1x 1/8″ steel,  1.5 x 1.5 x .062 steel, 2 x 2 x 1/8 aluminum

Capacities for Stainless steel are the same as for regular steel, but you’ll have to be more gentle.  Aluminum yield strength is about half the strength of steel, so you can likely bend twice the width of steel.

Description:

This Heavy Duty Slip roller has multiple positions for easier bending of tough, wide, or thick materials.  The upper hole setup is for sheet metal materials up to 12 gauge (.100 inch).  The second set is for materials up to 3/16″ thick.  The lower set of holes enable bending thicker materials, up to 2” thick.  The wider the spacing of the rollers, the easier it is to create the curve.  The wider the spacing, the larger the resultant radius.

> Slip-rolling is a slow process and usually requires 6-12 passes through the rollers, with small, incremental tightening on the adjuster block to achieve a smooth roll. Overloading a slip roller is very easy, however, can shorten the life of the unit. Exercise additional care when rolling hardened or stainless steels as you may damage the surface of the rollers.

> Depending on your material, these rollers may work better when covered in gorilla tape, duct tape, or other grippy materials.

>  To remove a full circle from the rollers, you will need to remove the center roller.  Removal, disassembly, and reassembly are all straightforward. Simply lower the adjuster bolt to release pressure from the system. Then unscrew the two end bolts from the top roller and remove the workpiece.
