Featuring high-elastic rubber rings and a heavy-duty structure, it effectively absorbs impact, reduces vibration, and prevents conveyor belt tearing and damage. An indispensable protective component for conveyor loading zones.
Core Product Values
- Impact Absorption to Protect Conveyor BeltsIn conveyor loading zones, materials falling from heights exert significant impact on belts. Long-term operation can easily cause:
- Belt wear-through and tearing
- Damage to carrying rollers
- Premature failure of roller bearings
- Conveyor belt joint breakageThe Impact Roller, with its high-elastic rubber buffer ring structure, absorbs up to 60%–70% of instantaneous impact force, effectively protecting conveyor belts.
- Heavy-Duty Steel Construction for High-Impact ConditionsThe roller body adopts thickened steel tubes, high-strength shafts, and heavy-duty bearings, ensuring superior performance under heavy-load, high-fall-height, and high-frequency impact conditions.
- Premium Rubber Rings for Wear & Aging ResistanceWe utilize:
- Natural Rubber (NR) high-elasticity material
- Heat vulcanization molding process
- High-wear-resistant rubber formulaResulting in buffer rings with high elasticity, tear resistance, wear resistance, and aging resistance — offering a service life far exceeding standard rubber rollers.
- Multi-Layer Sealing Structure for Extended Service LifeLoading zones feature high dust concentration, high humidity, and severe impact, requiring a reliable sealing system.Our solution includes:
- Triple labyrinth seal
- Rubber contact seal
- Optional waterproof sealEffectively prevents dust and moisture from entering bearings, extending service life by 30%–50%.
- Customizable for Diverse Working ConditionsCustomizable options:
- Roller diameter
- Number and hardness (Shore A) of buffer rings
- Shaft diameter
- Length
- Oil seal type
- Color / Rubber coating material
- Compliance with CEMA/DIN/JIS/DTII standardsMeets requirements for different drop heights, material characteristics, and load conditions.
