**Steel Troughing Idler Rollers for Belt Conveyor**
Steel troughing idler rollers are essential components in belt conveyor systems. They make up about 35% of the total cost of a conveyor belt and account for over 70% of the resistance, making their quality crucial for efficient operation.
These rollers are widely used across various industries such as food processing, cement, power generation, mining, chemical manufacturing, construction materials, steel production, and more. They play a key role in supporting the conveyor belt and ensuring smooth movement by reducing friction and providing stable rotation.
**Key Features**
| Three-seal design for dustproof and waterproof protection. |
| High strength and durability. |
| Minimal radial runout for stable performance. |
| Lightweight and energy-efficient design. |
| Long service life (over 50,000 hours). |
| Low radial runout (less than 0.35 mm for carrying idlers). |
**Applications**
Carrying idlers are commonly installed in belt conveyors and are widely used in coal mines, metallurgy, ports, construction sites, power stations, and chemical and food industries. They ensure that the conveyor belt remains properly supported and runs smoothly without excessive sagging or misalignment.
