HL005 Series Professional Sliding Window Roller

Beyond Conventional
Mobility Standards

At the core of the HL005 is a high-tensile SUS316 Marine Grade chassis, engineered to prevent bowing or structural fatigue. For Luoqi Door Systems, the HL005 is not just a component; it is a structural statement for **Aluminum Alloy Hardware** systems that push the boundaries of modern skyscraper and luxury estate design.

Each wheel features internal Ceramic-Hybrid Bearings as an optional upgrade, offering extreme hardness and thermal stability. The HL005 is the definitive **Premium Hardware Solution** for architects who refuse to compromise on the size of their glass or the smoothness of their motion.

Ultra-Max Capacity Mapping

◈ Quad-Point Distribution

By utilizing four contact points instead of two, the HL005 reduces the PSI (Pounds per Square Inch) on the track by 50%. This prevents track "pitting" and ensures a smooth glide for sashes that would otherwise require motorized assistance.

◈ Dual-Pivot Rocker System

The complex internal suspension allows the quad-wheel carriage to articulate over track debris or uneven floor levels. This "Self-Correcting" geometry maintains 100% wheel-to-track contact at all times.

◈ Ceramic Shield Protection

Designed for 2026's most demanding environments, the HL005 uses a high-performance ceramic coating on internal bearings to dissipate heat during high-frequency usage in luxury hospitality settings.
