38mm Roller Blind Mechanism Kit - China Suppliers, 1:1.65 Gear Ratio, Factory Wholesale for Window Treatments
38mm Roller Blind Clutch Mechanism — Reliable Chain Drive System for Professional Blind Fabrication
Provides a balanced trade-off between lifting speed and operating effort, reducing end-user fatigue when raising or lowering medium-to-large window coverings. Fewer chain pulls required per full travel compared to standard 1:1 systems.
Uses the most widely available commercial bead chain specification, simplifying your supply chain and reducing procurement complexity. Compatible with metal and plastic bead chains from major chain suppliers.
Designed for seamless press-fit insertion into standard T-001 specification 38mm aluminum roller tubes. No additional adapters or modification required, minimizing assembly time on your production floor.
Each unit ships as a matched set: clutch drive unit, pin end idler, drive end bracket, and idle end bracket. Your team opens one package and has all hardware ready for one blind — reducing parts sorting time and assembly errors.
Frequently Asked Questions (FAQ)
It is precision-engineered specifically for standard T-001 specification 38mm aluminum roller tubes, allowing for direct press-fit insertion without adapters.
The 1:1.65 gear ratio provides an optimal balance between lifting speed and physical effort. It requires fewer chain pulls to fully raise or lower the blind compared to standard 1:1 systems, reducing user fatigue.
This mechanism is fully compatible with standard 4.5×6mm bead chains, including both plastic and metal variations from standard commercial suppliers.
Each matched hardware set includes one clutch drive unit, one pin end idler, one drive end bracket, and one idle end bracket.
Yes, the system is engineered specifically for high-volume blind manufacturers and window treatment workshops to streamline assembly processes and reduce errors.
