ERW steel tubes for idlers for belt conveyors as per IS 9295-1983, in outside diameters from 63.50 mm to 219.10 mm. Tubes are sized with Rotary Sizing Machine (RSM) technology, which allows in-between non-standard diameters online without a tooling change and gives high diameter accuracy and roundness, improved surface finish and low residual stress. Stated end uses are conveyor idler tubes, propeller shaft tubes, bobbin tubes for the textile industry and high-precision or high-rotation applications.

Key features

• In-between non-standard diameters possible online without change of tooling
• RSM sizing gives very high diameter accuracy and roundness
• examples shown with tolerance of +/-0.022 mm
• Surface finish of incoming strip improved by 30%
• cold work reduced and energy savings considerable
• Even and low residual stress
• two cum-rotating cages used in RSM to avoid torsion load

Applications

• Idler Tubes for Conveyors
• Propeller Shaft Tubes
• Bobbin Tubes for Textile Industry
• High Precision Diameter
• High Rotational Application
