Precision Weightometer Rollers

SEC Business Group Weigh Rollers are engineered for conveyor weightometer systems where minimal vibration and precise idler concentricity are essential for accurate measurement.

Heavy-Duty Welded Construction

Steel bearing housings are welded directly to the roller shell to prevent separation under heavy loads, moisture ingress, or thermal expansion.

Advanced Sealing Protection

Fitted with 2RS NSK greased-for-life bearings and triple-labyrinth sealing systems to protect against dust, contamination, and harsh operating environments.

Precision Rollers for Conveyor Weightometer Systems

SEC Business Group Weigh Conveyor Rollers are specifically engineered for use in conveyor weightometer systems where minimal vibration, high accuracy, and precise idler concentricity are critical.

These rollers are typically installed in the weighing zone as well as the lead-in and lead-out positions to maintain belt stability and ensure accurate measurement throughout the weighing process.

Heavy-Duty Welded Construction

Manufactured with steel bearing housings and a heavy-duty steel shell, the components are welded together to create a robust and reliable assembly. This construction prevents the bearing housings from separating from the shell over time due to heavy loading, moisture ingress, or thermal expansion.

The bearing housing design also eliminates the sharp edges commonly associated with shell failures, reducing the risk of belt damage caused by the traditional
“pizza-cut” effect.

Advanced Bearing and Sealing System

SEC Business Group Weigh Conveyor Rollers are fitted with 2RS NSK greased-for-life bearings, supported by double-sided triple-labyrinth seals and an additional
dust seal with integrated labyrinth protection.

This advanced sealing system protects internal components from dust, moisture, and contamination, ensuring long service life even in demanding operating environments.

Designed for Heavy-Duty Mining and Materials Handling

Designed for heavy-duty materials handling applications, these rollers are suitable for installations ranging from small quarry operations to
large-scale mining environments including iron ore, hard rock, and coal operations. They are also suitable for underground conveyor systems.

All weigh rollers are powder-coated as standard and can be supplied in custom colours to match site or equipment requirements.
