Product Description

Luoqi Mechanical Engineering

Professional
Spindle Drive
Handle Series

The industrial standard for torque-driven security. A Premium Hardware Solution optimized for high-performance Aluminum Alloy Hardware transmission systems.

Standard: DIN 18267 Compliant

Zero-Play
Mechanical Transmission

The Professional Spindle Transmission Handle Series is the backbone of modern window actuation. Luoqi Door Systems has engineered this series to eliminate the "loose handle" sensation, ensuring that every degree of rotation is translated into immediate locking movement.

By utilizing a hardened 7x7mm square spindle with micron-level tolerances, we ensure a perfect fit with all standard Window Hardware gearboxes. This high-torque stability is critical for aluminum alloy Hardware systems where multiple locking points create significant operational resistance.

Spindle Attributes

◈ Hardened Grade 8.8 Carbon Steel
◈ Anti-Fracture Torque Core
◈ Universal 7x7mm Square Profile
◈ Dynamic Length Customization
◈ Corrosion-Resistant Zinc Plating
◈ "Snug-Fit" Precision Milling

Engineered Connectivity

Optimized for the Professional Gearbox ecosystem.

High-Torque Performance

Commercial windows require high force to engage perimeter seals. Our Professional Spindle Handles are tested to withstand over 50Nm of torque, far exceeding the requirements of standard Window Hardware installations.

Multi-Stage Detent

The internal clicking mechanism features a reinforced ball-bearing detent. This provides a crisp 90° feedback, ensuring the user knows exactly when the Aluminum Alloy Hardware system is fully locked or in the ventilation position.

Universal Retrofit

With a standardized 43mm screw center, the series is the perfect Premium Hardware Solution for both new construction and large-scale maintenance retrofitting in commercial skyscrapers.

Aesthetic Versatility

Despite its industrial strength, the handle body is finished to architectural standards. Available in matte, satin, and polished PVD coatings to match any Aluminum Alloy Hardware profile.

Actuation Specification

◈ Structural Integrity

The spindle is secured to the handle hub using a high-tensile retaining clip and industrial-grade adhesive, preventing "spindle pull-out" in heavy-duty or high-security applications.

◈ Acoustic Management

Internal nylon bushings isolate metal-on-metal contact, delivering a silent operation that is a hallmark of Premium Hardware Solutions in luxury environments.
