Product Overview
Our 20 Ton Self-Aligning Welding Rotator, a reliable type of Cylindrical Workpiece Turning Rolls, consists of driving unit and idler unit.
Its self-swing roller mechanism automatically adapts different diameters of cylindrical workpieces, eliminating repeated manual adjustment work.
With stable variable-frequency rotation, it works with SAW, MIG and TIG machines to realize consistent circumferential welding for heavy cylindrical components.
Greatly improve production efficiency for vessel and pipe fabrication workshops.

Operation Guide
Before Use
Place the Cylindrical Workpiece Turning Rolls on flat solid ground, align driving and idler units on one central line. Check bolts and power supply.
Workpiece Placement
Set cylindrical workpiece on rollers; self-aligning mechanism swings automatically to support the component steadily.
Safety Reminder
Do not stand beside rotating cylindrical workpiece. Trigger emergency stop once abnormal vibration or noise occurs.

Frequently Asked Questions
Q1: What is the advantage of self-aligning Cylindrical Workpiece Turning Rolls compared with bolt adjustable type?
+
-
A1: Self-aligning rotator automatically adapts cylindrical workpiece diameters without manual adjustment, saving clamping time, more suitable for multi-spec cylindrical parts production. Bolt adjustable model requires manual roller spacing adjustment, cost-effective for fixed-size workpieces.
Q2: Can this equipment weld stainless steel cylindrical tanks?
+
-
A2: Yes. Standard PU rollers avoid scratches on stainless steel surfaces. Choose steel rollers if working under high welding temperature.
Q3: Can we customize power voltage?
+
-
A3: Yes, 220V, 380V, 415V three-phase available. Please confirm voltage before order.
Q4: Warranty policy?
+
-
A4: One-year warranty for motor, inverter and reducer (exclude man-made damage). Operation manual, wiring diagram and online technical guidance supplied.
What is the lead time and payment term for these cylindrical workpiece turning rolls?
+
-
A5: Standard lead time is 12~20 working days after deposit for 20 ton self-aligning models. Accepted payment terms: 30% T/T deposit in advance, 70% balance before shipment. L/C at sight is also acceptable for formal orders. We will update production progress and send test videos before delivery.
