Constructed with high-strength steel structure and multi-seal technology, effectively reducing wear and resistance to ensure long-term stable operation of conveyor systems.
Core Product Values
- Ultra-High Concentricity Design for Smoother OperationThe roller shell undergoes automatic welding and CNC turning processes, with concentricity deviation controlled within ≤0.7mm, effectively minimizing conveyor belt misalignment and vibration.
- Low Rotational Resistance to Reduce Energy ConsumptionRotational resistance of carrying rollers directly impacts the energy consumption of the entire conveyor line.We adopt:
- High-precision deep groove ball bearings
- Optimized labyrinth seal structure
- Dynamic balance treatment for precision steel tubesResulting in starting and rotational resistance that is 15%–25% lower than the industry average.
- Multi-Layer Sealing System for Superior Dust/Water ProtectionThe roller’s sealing structure is critical to its service life.Our triple-seal system includes:
- External labyrinth seal: Blocks large-particle dust
- Internal labyrinth seal: Blocks fine dust
- NBR or silicone contact seal: Resists water, oil, and sludgeEnsures long-term trouble-free operation even in harsh environments such as open-air, waterlogged, or high-dust conditions.
- High-Strength Materials & Surface Treatments for Enhanced Wear ResistancePremium materials selected for durability:
- Q235/Q345 high-quality steel tubes
- 45# or 40Cr solid shafts
- Optional anti-corrosion treatments: Powder coating, hot-dip galvanization, epoxy coatingOffers excellent strength, impact resistance, and corrosion resistance.
- Long-Life Bearing Options (Domestic/Imported)Optional bearings:
- Domestic high-precision bearings (6204～6312 series)
- Imported bearings (NSK, SKF, FAG, etc.)Paired with high-precision bearing housings, it reduces operational resistance and extends roller service life to 30,000–50,000 hours (depending on working conditions).
