ROUNDO 3-Roll Plate Bending Rolls (110, 150, 185)

For the sheet and light plate fabricator desiring the most modern, versatile three-roll double pinch plate bending roll for their shop, ROUNDO makes available their line of smaller Ps-style machines with the Series 110, 150, and 185 models. With superior prebending capability and the capability to roll to diameters as small as 1" larger than the standard top roll diameter, these machines provide the same quality results as four-roll double pinch or three-roll single pinch machines. The two lower rolls can be adjusted independently of each other, with infinitely variable adjustment speeds, in a curved path around a common center. The standard rolls are manufactured of high-carbon-content steel forgings for maximum surface hardness. A single hydraulic motor drives all three rolls, allowing any one, two, or all three rolls to provide 100% of the drive torque at all times. This drive system design is the simplest to maintain, yet the most effective delivery system for drive torque. All shafts including the rolls are journalled in SKF spherical roller bearings to keep friction losses to a minimum.
