The heavy-duty roller provides power to the conveyor and is used together with the reducer and motor. Generally, there is a rubber coating on the surface, which can increase friction and reduce power loss; using thickened iron sheet can increase the pressure resistance of the roller; thickening the shaft can provide longer use time. It is widely used in heavy-duty conveyors and can meet the requirements of long-distance transportation.

HDR heavy-duty conveyor rollers are engineered to deliver high-performance and extended service life (typically 8 years with 24/7 operation) in demanding bulk material handling environments. Their robust design incorporates premium-quality components and materials:
Precision steel tube to DIN 2458, electrically welded with tight tolerances to ensure minimal radial run-out, reduced imbalance, and quiet, smooth operation.
Carbon steel shaft ST37 to DIN 17100, offering the required strength and resilience for heavy-duty applications.
Forged steel bearing housings with tight tolerances, ensuring durability and precise alignment.
Deep groove precision ball bearings, lubricated with lithium grease NLGI 2 for long-term protection against dirt and water ingress.
Non-contacting triple-lip labyrinth seals, with a heavy-duty circlip cover cap made from cold-pressed deep-drawn steel (DIN 1623/1624), zinc-plated for added durability.
Roller shell and axle treated with a special long-life wax to resist rust and corrosion.
