Featuring a mechanical self-adjusting structure, it automatically corrects conveyor belt misalignment, effectively protecting the belt and improving system continuity. An essential deviation correction component for large and medium-sized conveyors.
Core Product Values
- Automatic Deviation Correction to Prevent Belt MisalignmentThe Self-Aligning Roller automatically adjusts the roller angle when the conveyor belt drifts, guiding the belt back to the central position — no electrical control or manual intervention required.It effectively solves the following issues:
- Conveyor belt misalignment
- Accelerated edge wear
- Belt tearing
- Damage to belt joints
- Frequent shutdowns caused by misalignmentEnsures continuous and stable operation of conveyors even in complex environments.
- Multi-Point Guiding Design for Precise CorrectionThe Self-Aligning Roller typically adopts the following structural combination:
- Guide Rollers
- Center Roller
- Pivoting FrameWhen the belt drifts to either side, the guide rollers generate lateral force, and the pivoting frame automatically adjusts its angle to naturally guide the belt back to the correct path.Offers high sensitivity, fast response, and stable performance.
- Heavy-Duty Structure for Harsh Working ConditionsAs a critical component in conveying systems, the Self-Aligning Roller features reinforced construction:
- Thickened bracket steel plates (6–12mm)
- High-strength roller shafts
- Precision-welded frame
- High-load-bearing bearings
- Engineering-grade sealing structureCapable of withstanding long-term operation under heavy loads, high dust, and corrosive environments.
- High-Efficiency Sealing System for Extended Service LifeEquipped with a triple-seal structure:
- Outer labyrinth seal: Blocks large-particle dust
- Inner labyrinth seal: Blocks fine dust
- Contact-type waterproof seal: Prevents water and sludge from entering bearingsSuitable for: Outdoor applications, mining, high-humidity, and high-dust environments.
- Full-Series Customization for Universal Conveyor CompatibilityCompliant with international standards:
- CEMA
- DIN
- JIS
- DTII
- GBCustomizable options based on customer requirements:
- Roller diameter
- Belt width
- Bracket angle
- Number and structure of rollers
- Surface treatmentCompatible with conveyor belts of 500–2400mm width.
