Manual Screw Adjustment Conventional Welding Rotator

Our heavy duty, built to last conventional rotators and turning rotators are designed and manufactured to tolerate the hardest, hard-wearing and unrelenting workload environments. The powered drive units are controlled by a five-function pendant with a variable speed potentiometer, giving the operator full control of the rotating workpiece.

Why Do We Need Welding Rotator?

When performing a weld on a pipe or cylindrical work piece, usually the weld must cover the circumference of the pipe evenly. It’s also important for the weld to be of a high quality and strong, as a lot of pressure could be put on the pipe depending on what the final work is meant for.


When pipe welding is done by hand, the welder must move around the pipe slowly as they carry out the work. Without something like a Bode welding rotator, this is difficult and necessary work in order to get the correct weld. Using a pipe turning rolls enables the tank/vessel to be turned at desired speeds enabling the welder to carry out the work far easier & more efficiently, giving a higher quality weld to form roll steel tubulars.


Welding rotators are usually arranged in sets including a pair of identical rolls, one of which is rotated by an electric motor through a reduction gear box, known at the powered or drive unit while the other is idle, so arranged that the distance between the rolls can be adjusted to accommodate cylinders of different diameters, and mounted on a fabricated frame of simple shape. Usually a pair of such frames must be arranged on the shop floor at some distance from one another, to accept the cylindrical body in need of welding. Weight capacity and diameters that can be supported are the major parameters that define welding rotators. Other characteristics involve wheel and surface materials, power and surface speed available. The free turning of the part on the rolls should be ascertained before the start of the welding operation, to verify that no protrusions interfere with the motion. Also the longitudinal weight distribution should be checked to prevent overloading. Special attention should be paid to avoid instabilities that may cause the work piece to overturn. Minute inaccuracies of positioning may involve translation of the work piece along its axis. None parallelled or out of square turning rolls may cause drag forces that tend to move the work piece unpredictably. Welding rotators are supplied with steel, rubber or polyurethane wheels.


What Are the Parts of a Tank Rotator?

Image where you can clearly see the parts and components of tank rotators

The traditional tank rotator is comprised of two (2) parts:

When dissected, each of them would have different parts, too!

Idler Supporting Unit

The idler support, or more commonly referred to as the “base” is the part that carries the wheels or the mediums that perform the rotation or the twisting of the workpiece.

Parts of the idler supporting unit include:


Motorized Drive Unit

Akin to the idler supporting unit, the motorized drive unit is also comprised of different parts and components.

For the benefit of everyone, the motorized drive unit is the part of the rotator that gives off the power and the energy to make the tank rotator work.

The controller and the motor are two (2) of the most important parts of the motorized drive unit.

These are the parts of a tank rotator. Some tank rotator manufacturers and suppliers might add too few parts and components to complement it, but these are the parts of a traditional rotator.
