DIRECT GUIDES 75% fewer moving parts
LOW MAINTENANCE Reduces costs
DIRECT DRIVEN ROLLS High efficiency, design simplicity

TECHNICAL FEATURES

• 6 LED digital displays monitor lateral and pinch rolls

• Mobile console with low voltage push button controls

• Top roll and pinch roll driven by radial piston motors direct coupled to shafts for near 100% efficiency

• Fully hydraulic operation of drop end & tilt of lateral + pinch rolls

• Lateral roll movement with 75% fewer moving parts than competitors torsion systems means total reliability, lower maintenance and cost savings

• Pinch pressure adjustable for plate thickness, material type and diameter

• Pinch roll inclines for cone rolling, solid state controlled

• Roll rotation on high dynamic load self aligning spherical roller bearings

• Positive parallel system on pinch and lateral rolls, fully proportional controlled on PBS Series units

• Oversized low profile end frames for unsurpassed strength at max. loading
