Featuring a spiral design, it automatically guides the conveyor belt back to the central position, reducing belt wear and extending the service life of both the roller and the conveying system.
Core Product Values
- Automatic Deviation Correction DesignThe spiral surface of the roller generates lateral force when the conveyor belt drifts, guiding the belt back to the central position automatically. Effectively avoids:
- Conveyor belt misalignment
- Belt edge wear
- Frequent shutdowns for maintenance
- Damage to belt joints or rollers
- Precision Manufacturing for Smooth Operation
- CNC machining
- Strict concentricity control
- Smooth rotation with minimal vibrationEnsures stable operation of the conveyor belt under high-speed and heavy-load conditions.
- High-Strength Materials
- Roller Shell Material: Q235/Q345 Steel or Carbon Steel
- Shaft Material: 45#/40Cr Forged Steel
- Surface Treatment: Powder Coating, Hot-Dip Galvanization, Optional Stainless SteelHigh-strength structure with excellent bending resistance, heavy-load capacity, and impact resistance.
- Multiple Types Available
- Spiral Carrying Roller
- Spiral Return Roller
- Helical Guiding RollerCustomizable spiral rollers for inclined or long-distance conveyors.
- Efficient Sealing System
- Dual/Triple Labyrinth Seal
- Dust, Water, and Sludge Resistant
- Optional High-Temperature SealEnsures long-term stable operation of the roller in dusty, humid, or extreme environments.
