Premium Stainless Steel & Plastic Composite Pulley for Doors & Windows

High-grade 304 stainless steel core ensures superior strength & corrosion resistance, reinforced with precision-molded POM plastic for ultra-smooth rolling.

Laser-polished bearing channels reduce friction by 40% vs standard pulleys, enabling whisper-quiet sliding motion even under heavy loads (max 50kg).

Dual-track sealing design prevents dust buildup, ideal for high-humidity areas like bathrooms, balconies, and coastal properties.

CNC-machined mounting holes guarantee perfect alignment during installation, compatible with European/US track systems (8-12mm groove width).

Industrial-grade nylon rollers withstand 100,000+ cycles, perfect for commercial storefronts, sliding patio doors, and warehouse partitions.

Direct factory pricing available for bulk orders (MOQ 500pcs), with custom branding options for wholesalers.
