20Ton welding turning rolls for cylinders
,Self-aligning welding rolls for pipe welding
,Pressure vessel girth welding turning rolls
This 20-ton self-aligning welding rotator consists of one drive frame and one idler frame. Roller groups automatically adjust angle to adapt different cylinder diameters without manual adjustment. It delivers stable, low-noise rotation for girth welding of pressure vessels, boiler barrels, large-diameter pipes and tank shells. Reserved synchronous interfaces support linkage with welding manipulators and automatic welding systems, widely adopted for heavy-duty cylinder batch fabrication.
- Self-aligning structure, rollers auto-adjust angle according to workpiece diameter, save setup time
- Heavy-duty welded steel base, high rigidity for long-time continuous workshop operation
- Polyurethane rollers, high friction, no scratching on workpiece surface, long service life
- VFD stepless speed regulation, forward / reverse rotation, stable running under full load
- Hand-held control pendant with emergency stop function, simple operation
- Reserved synchronous control interface for connecting manipulator / SAW welding system
- Customizable voltage, roller material and multi-idler combination

Unlike conventional adjustable rotators, this self-aligning model enables automatic roller angle adjustment. No manual screwing or re-positioning is needed for different cylinders, cutting setup time for multi-spec batch production.
High-performance integral PU rollers deliver wear-resistance, anti-slip and cushioning. They avoid scratches on carbon steel, stainless steel and alloy parts. Smooth low-noise full-load rotation guarantees consistent weld formation.
Built-in VFD provides precise stepless speed control. Reserved synchronous interface supports connection with welding manipulators, SAW systems and robots for automated girth welding and fewer human errors.
Thick-plate welded frame offers high rigidity and heavy-load anti-deformation performance. Premium transmission and motor parts ensure low failure rate and reduce after-sales maintenance expense.
This 20-ton self-aligning rotator includes one drive and one idler frame. Its swing-type roller supports auto-adapt contact angles to match cylinder outer diameters for full-contact stable support. The drive unit transfers power via friction to achieve adjustable uniform rotation of workpieces for girth welding, with synchronous signal matching for welding equipment.
A: Roller brackets swing automatically to fit different cylinder diameters. No manual screw adjustment required when changing workpieces.
A: Yes. Synchronous interface is reserved. Please advise your manipulator model for signal matching.
A: 1-year warranty against manufacturing defects. 24/7 online technical support. Spare parts at cost after warranty period.
A: Yes, multiple idler frames can be configured according to your workpiece length. Please offer workpiece drawing for proposal.
A: Please control workpiece eccentricity within 15% of rated load. Severe eccentric load is forbidden.
