Polyurethane slide conveyor wheels are engineered exclusively for automotive skid conveyor systems, serving as core components for welding, painting, and final assembly lines. Featuring a high-strength steel core and wear-resistant polyurethane tread, these wheels deliver exceptional load capacity, low noise, chemical resistance, and long service life—critical for reliable, high-efficiency automotive manufacturing.
Key Features & Benefits
Ultra-High Load Capacity
• Single-wheel dynamic load: 1–5 tons (custom up to 10 tons)
• Steel core with heat treatment for maximum structural rigidity
Application-Specific Hardness
• Welding lines: 90A–98A (impact & heat resistance)
• Assembly lines: 70A–85A (noise reduction & floor protection)
Superior Wear Resistance
• Polyurethane tread: 3–5× more durable than rubber
• Akron abrasion: 0.02 cm³/1.61 km (polyether-grade formula)
Low Noise & Smooth Operation
• Noise level: <60 dB at 24 m/min (typical line speed)
• Precision bearing + curved tread design minimizes vibration
Chemical & Environmental Resistance
• Resists oils, greases, weak acids, and paint shop chemicals
• Temperature range: -30°C to +100°C
Precision & Durability
• TIR (runout): ≤0.05 mm for high-speed stability
• Service life: 12–18 months (24/7 operation, 300 kg load)
Easy Installation & Maintenance
• Modular bolt-on design for quick replacement
• Sealed bearings prevent contamination in harsh environments
