Turning Rolls

Turning rolls are inherently simple positioners with many productive options. They can either be powered or not. Or we can mount rolls on a tilting frame to make tilting-turning rolls. We put rolls on rail cars to transport vessels through a fabrication shop and into shot-blast or X-ray chambers. We also invented the Trac-Tred ® roll that combines turning rolls with a tractor-tread cradle, forming an endless sling for handling thin or weak-walled work.

The basic turning-roll setup includes a driver with two powered wheels, and a companion idler which is freewheeling. The driver supports one end of the workpiece and imparts rotational motion to the work. The idler set merely supports the other end of the workpiece as it rotates.

Offering the widest variety and capacity ranges of turning rolls in the world, Koike Aronson / Ransome always has a fit for your application. Variable speed powered rotation with constant or variable wheel centerline settings are available.

Preferred usages of various materials for Turning Roll Wheels:

Rubber, Steel, Urethane, and Micarta (phenolic) wheels are also available. Traditional, Unitized, Self-Adjusting (SA), Trac-Tred®, Turbine, and Tilting rolls are just some of the models we offer.

Rubber - Normal material used on Rolls for general usage.  Provides giving surface for diameters that may be machined, or vessel surfaces that should not be marked.  For higher loads, a greater wheel width is required to accommodate weight.

Urethane - Used generally for same as Rubber.  Harder material that can, in certain circumstances, provide greater Tractive Pull when required.  Does not require as much increase in wheel width under increased load as rubber.

Steel - Provides greatest amount of Tractive Pull.  Used when load has to be concentrated on smaller footprint.  Minimal deflection under load.

Micarta - Used in special circumstances when load is highly concentrated (as in journals on rotors and armatures) and will ride on machined surfaces.  Unlike steel, which might damage machined surfaces, Micarta will not.  In addition, unlike steel, chips that do end up on the wheel surfaces will end up embedded in the Micarta surface.  Minimum wheel width is very dependent on the tracking surface (on the work piece) vs. the weight of the workpiece.  The Micarta material used in the wheels can be fairly easily replaced if necessary.

Manual or powered mobile sub-base cars can be included for quick adjustment of varying vessel lengths.

Special engineered turning rolls are always available.
