Quick Summary

The BW-SK Spring Kit Mechanism is a cordless, quiet, and durable lifting solution tailored for
bamboo and wood roller blinds. Using a stainless spiral spring inside a reinforced POM housing, it delivers
stable torque for heavier natural fabrics, smooth lifting without rebound, and long service life. Modular adapters support 38 mm/43 mm tubes; torque can be
factory-calibrated for OEM integration.

Product Overview

Built for natural materials with higher areal weight, the Bamboo/Wood Roller Blinds Spring Kit balances panel mass through a precision-matched
spiral spring. The mechanism holds any height reliably, eliminates external cords, and reduces assembly complexity compared with clutch/chain systems.

Technical Specifications

Model Tube Rated Tension (g) Itinerary Ref. Panel Width Ref. Spring Type Housing
BW38-SK500 Ø38 mm 500 96″ / 2400 mm ≤ 2.4 m (bamboo) 301 SS spiral spring POM
BW38-SK600 Ø38 mm 600 84″ / 2130 mm ≤ 2.1 m (bamboo/wood) 301 SS spiral spring POM
BW43-SK700 Ø43 mm 700 72″ / 1830 mm ≤ 1.8 m (heavy slat) 301 SS spiral spring POM (reinforced)

Notes: References assume typical bamboo fabric mass 250–400 g/m². Final selection depends on panel width, drop, tube stiffness, and bottom-bar mass.

Key Features

  • Cordless spring mechanism—eliminates bead chains, reduces >90% entanglement risk.
  • Calibrated torque curve for bamboo/wood weights; holds position without creep or kickback.
  • Quiet operation via low-friction POM guides and balanced spiral geometry.
  • Modular adapters for 38/43 mm tubes; quick drop-in with standard headrails.
  • Long life—10,000+ cycles target with ±5% tension stability under normal use.
  • Service-free—no lubrication; corrosion-resistant 301 stainless spring.

Installation Notes

  1. Verify tube diameter (38/43 mm) and choose matched drive/idle adapters.
  2. Insert the spring box into headrail; lock using the designated clip orientation.
  3. Pre-tension per model label (e.g., 2–3 turns) before mounting the tube.
  4. Balance check: raise to mid-height; panel should stay without drift—adjust pre-tension if needed.
  5. Avoid high humidity exposure during storage; install above child reach.

Applications

  • Bamboo roller blinds for living rooms, bedrooms, tea rooms, resorts.
  • Wood veneer blinds and other heavier natural fabrics.
  • Light-commercial cafés, boutique hotels, studios requiring cordless safety.

FAQs — Bamboo/Wood Roller Blinds Spring Kit Mechanism

How do I choose a model for my panel?

Provide tube diameter (Ø38/Ø43 mm), panel width & drop, and fabric mass (g/m²). We calculate the recommended rated tension and itinerary reference to balance bamboo/wood panels without drift.

Can I fine-tune the balance on site?

Yes. Add or remove pre-tension turns before the final end-cap lock, then test at mid-height. Panel should hold position without creeping up or down.

Is an internal brake required?

The spiral spring’s torque curve and POM guides usually hold position without a brake. For heavier panels or wide tubes, request the brake-assisted variant.

What maintenance is needed?

None in normal indoor use. Annually check for dust buildup, verify set-screws on tube/end-caps, and inspect bottom bar alignment. Do not lubricate.

What are the recommended operating conditions?

Indoor only: 0–40 °C, relative humidity <85% non-condensing. Store the spring kit dry, away from solvents and corrosive atmospheres.

Which materials and finishes are used?

Housing: POM (low friction, dimensional stability). Spring: 301 stainless steel (corrosion-resistant). Adapters/ends: aluminum/steel with protective finishing.

What panel sizes and weights are supported?

Reference: BW38-SK500 ≤ 2.4 m width (bamboo), BW38-SK600 ≤ 2.1 m, BW43-SK700 ≤ 1.8 m heavy slats. Final selection depends on g/m², tube stiffness, and bottom-bar mass.

How do I troubleshoot creeping or rebound?

Re-set pre-tension by ±½–1 turn. Ensure tube set-screws are tight and fabric is squarely rolled. If rebound persists on heavy panels, move to a higher-tension model or brake-assisted kit.

Is the kit compliant with child-safety rules?

The kit enables a cordless system configuration that supports compliance pathways under CPSC 16 CFR 1260 and ANSI/WCMA A100.1. Final conformity must be validated on the finished blind.

Can you support OEM/ODM customization?

Yes. Options include rated tension curves, adapter geometry for Ø38/Ø43 mm tubes, end-cap interfaces, branding, packaging, and pilot runs. Typical evaluation MOQ: 10–20 sets.

How do I choose a model for my panel?

Provide tube diameter, panel width & drop, and fabric mass (g/m²). We calculate the recommended rated tension and itinerary reference.

Can I fine-tune the balance on site?

Yes. Add or remove pre-tension turns before final end-cap lock, then re-test at mid-height.

Is an internal brake required?

The spiral spring’s torque curve and friction guides typically hold position without a brake. For very heavy panels, ask for a brake-assisted variant.

What maintenance is needed?

None in normal indoor environments. Inspect annually for dust buildup and tube set-screws tightness.
