SIH-PBS
Proportional Balancing System

Overhead & Lateral Supports Optional on all SIH & SIHR Models

• 3 Rolls Driven by Independent Direct Coupled Hydraulic Drives for near 100% torque delivery to the workpiece.
• Electronic Proportional balancing System maintains roll parallelism or cone incline via microprocessor. Simple, Reliable, Precise, Eliminates maintenance, Reduces moving parts by 80% over torsion balanced systems.
• LED Displays monitor both ends of lower rolls.
• Cone Rolling Device and Automatic Lateral Roll Inclination standard on SIH-PBS
• Spherical Roller Bearings, Force Lubricated for Smooth, Efficient, Energy Saving Operation.
• Lateral Rolls move in Rectilinear Inclined Guides with non-metallic gibbs for a Rugged and Simple design delivering Maximum Cylinder Tonnage to the Rolls. SIH-PBS System eliminates over 75% of the mechanical parts found on other systems, reduces maintenance and Significantly extends Machine Life.
• Massive Reinforced Single Weldment End Frames offer Rigidity and Strength
• Forced Central Lubrication System.
