Belt Tracking Roller

• Immediate effect - fast automatic tracking response at the very first sign of deviation
• Maintenance free
• Easy to install
• Adjustable steering strength
• Models for single direction and reversible belts

HM410 Belt tracking roller begins to guide the belt immediately after the sideways movement has happened. This tracking device can be used also with reversible belts.

• Belt width: 450 - 2400 mm (18"- 96")
• Roller coating: Steel, rubber, polyurethane
• Roller diameter: 159, 219 mm (6.3", 8.6")

One of the most common challenges when operating a belt conveyor is to maintain the alignment of the belt. When installing a conveyor, it is good practice to make sure that both pulleys and idlers are aligned together with the structure and each other. Poor belt tracking, caused by misalignment of a conveyor, can be fixed either by forcing the belt over to one side or by installing a tracking device.

Efficient tracking solution

The Sandvik HM410 belt tracking roller is a better way to keep the belt aligned. The HM410 is a return belt tracker that helps align the belt without causing any additional wear to the belt or the structure. The HM410 brings results instantaneously so that the belt will not travel sideways as it would with a traditional tracking device.

• Models for single direction and reversible belts
• Fast automatic tracking response at the very first sign of deviation
• Adjustable steering strength
• Easy to install on existing and new conveyors; no extra space or extensive modification to structure
• Belt widths from 450 mm to 2400 mm (18"- 96")
• Roller diameters 159 mm and 219 mm (6.3", 8.6")

The HM410 is installed underneath the return belt, and due to its automatic response to misalignment, results are achieved immediately. There is no need to wait for the belt to make contact with the side rollers, which is the case for traditional tracking devices. The HM410 belt tracking roller is easy to install onto an existing or a new conveyor, since it does not require extra space or extensive modification to existing structure. The mounting brackets can be moved along the shaft very easily, which allows simple installation to different frame widths.

Normal belt travel
Center of gravity of the belt and roller are in the middle. The roller is both level horizontally and square to the direction of the belt.

Correcting misalignment
When the center of the belt is offset from the center of the conveyor, the weight of the belt forces the end of the roller downwards, which in turn tilts the roller diagonally in the direction of the belt travel. The tilted HM410 roller will then help “train” the belt back to the middle of the conveyor. When the weight of the belt is centralised, the roller will immediately return to its original position.

The HM410 belt tracking roller replaces one of the return rollers. The distance of the belt tracking roller to the next return roller must not be less than 3 meters (9.8 ft). The belt tracking roller is installed at the same level with the other return rollers.

The HM410 belt tracking roller must not be installed at a point where the belt is bending or there are excessive forces on the roller. Avoid locations that are marked with an X as shown on the drawing on the preceding page.

The most efficient point to install the HM410 belt tracking roller is before the tail pulley. In the case of a reversible conveyor it is preferable to install at least two devices – one near each end. If the conveyor is too short for more than one unit, then locate the HM410 belt tracking roller before the pulley that will be the tail pulley for the majority of the time.

For improved performance on longer conveyors, several HM410 belt tracking rollers should be installed. Spacing between rollers should be about 35-40 meters (114-131 ft).

Applicable on reversible and single direction belt conveyors
Through advanced engineering, the HM410 belt tracking roller D-range is designed specially for reversible conveyors. Type S can be used only for one direction conveyors.

Adjustable steering effect
The steering effect from the HM410 tracking roller can be easily adjusted to meet the requirements for light, medium and heavy weight belts.

Attaching alternatives
Moveable attaching parts in the direction of the roller shaft enable the easy and quick attaching to the different frame types and widths.
