SEC Business Group Steel Rollers provide a conventional and highly
reliable solution for demanding conveyor applications, offering
exceptional durability and long service life.

Robust Welded Construction

Steel bearing housings welded directly to the roller shell provide
superior structural strength while preventing housing separation
caused by heavy loads or thermal expansion.

Advanced Sealing Protection

Equipped with 2RS NSK greased-for-life bearings and a
triple-labyrinth sealing system to protect internal components
from dust, moisture, and contamination.

Description

Heavy-Duty Performance for Demanding Conveyor Applications

SEC Business Group Steel Rollers provide a conventional, heavy-duty and highly reliable solution for conveyor systems operating in demanding environments. Constructed with steel bearing housings and a heavy-duty steel shell, the components are welded together to create a strong and durable assembly.

This welded construction prevents the bearing housings from separating from the shell over time due to factors such as heavy loading, moisture ingress, or thermal expansion.

Robust Welded Construction

The bearing housing design eliminates the sharp edges typically associated with shell failures, reducing the risk of the traditional “pizza-cut” damage that can occur to conveyor belts.

This structural design provides a reliable and durable roller assembly capable of operating in harsh conveyor environments where strength and longevity are essential.

Advanced Bearing and Sealing System

SEC Business Group Steel Rollers are fitted with 2RS NSK greased-for-life bearings and incorporate double-sided triple-labyrinth sealing systems along with an additional dust seal featuring a labyrinth design.

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

Designed for Mining and Materials Handling

Steel rollers are particularly suited for heavy-duty materials handling applications ranging from small quarry operations through to large-scale mining environments including iron ore, hard rock, and coal operations.

While heavier than alternative roller types, steel rollers provide exceptional durability and are robust enough to withstand rough handling during storage, transport, installation, and operation.

They are also suitable for underground applications.

Available Coating Options

  • Inorganic Zinc Silicate Primer
  • Galvanising
  • Rubber Lagging
  • FRAS Rubber Lagging
  • Ceramic Lagging
  • Polyurethane Lagging

All rollers are supplied powder-coated as standard and can be
colour-matched to site requirements. Additional coatings are available
to further enhance shell durability and corrosion resistance.
