Trusted Flat Spiral Spring Supplier in India

Flat Spiral Spring Supplier in India | Precision Clock & Power Springs - Durga Spring

Trusted Flat Spiral Spring Supplier in India

Introduction 

Flat spiral springs are engineered to store energy and deliver controlled torque through a compact, coiled strip design. Durga Spring is a dependable flat spiral spring supplier in India, supporting OEMs and maintenance teams with consistent, repeatable spring performance for rewind, clockwork, tensioning, and return mechanisms. Our flat spiral springs are produced with stable material quality, accurate inner and outer end formations, and reliable winding characteristics. Whether your application requires smooth torque output, predictable return action, or long cycle life, we manufacture spiral springs that integrate cleanly into housings, reels, drums, and compact assemblies across Indian industries.


How We Manufacture Precision Flat Spiral Springs

A high-performing spiral spring depends on strip selection, geometry control, stress distribution, and end-hook accuracy. We ensure reliable results through disciplined production steps:

  1. Material and Strip Conditioning: We use suitable spring steel strip and ensure consistent thickness and edge condition for stable winding and reduced stress concentration.
  2. Controlled Coiling and Forming: Coiling is monitored for inner diameter, outer diameter, number of turns, and pitch control to meet torque and space requirements.
  3. End Formation Accuracy: Inner and outer ends are formed as per housing design (hooks, loops, tabs, or slots) to prevent slip and ensure reliable engagement.
This approach helps deliver flat coil springs that maintain consistent torque output and dependable return action through repeated cycles.


Applications & Benefits — Flat Spiral Springs in Real Use

Common Applications
  • Rewind mechanisms for reels, cords, and retractors in compact assemblies.
  • Clock and timer mechanisms requiring smooth, controlled torque delivery.
  • Tape measure and tool reels needing consistent return force.
  • Safety covers and shutters with controlled opening and closing action.
  • Industrial devices with drum-based energy storage and return motion.
Performance Benefits
  • Compact energy storage in limited space compared to conventional springs.
  • Controlled torque output for smooth and predictable operation.
  • Reliable engagement with accurate end formations to prevent slip.
  • Reduced vibration and chatter when torque is tuned to the mechanism.
  • Long service life with stable spring behavior over repeated cycling.

Selecting the Right Spiral Spring for Your Assembly

  • Define torque requirement and working angle to select strip thickness, width, and number of turns correctly.
  • Match inner and outer end style to the housing design to ensure secure anchoring and smooth winding.
  • Confirm available OD/ID space and coil direction to avoid interference during operation.
  • Choose appropriate surface condition and protection when used in humid or mildly corrosive environments.
  • Provide the assembly drawing or drum/housing detail for accurate fit and consistent repeatability.

Reliable Supply for OEMs, Service Teams, and Assemblers

As a flat spiral spring supplier in India, Durga Spring supports both development and repeat supply. We work with customer drawings, sample-based development, and requirement-driven selection to help you achieve the required torque curve and compact fit. From rewind springs and clock springs to reel springs and flat coil springs, we focus on repeatability, consistent end forming, and stable performance so your mechanism runs reliably over its intended service life. Share your application details and space constraints with our team to align spring design with real-world loading and cycle expectations.


Maintenance & Safety Tips — Better Life for Spiral Springs

Checklist Durga Spring

Installation & Fit

  • Ensure the inner and outer end hooks are seated correctly in the housing slots to prevent slip, uneven winding, or sudden release.
  • Maintain correct clearance between the coil and housing wall to avoid rubbing, heat build-up, and premature fatigue cracking.
  • Do not over-wind beyond the designed working angle, as excess winding increases stress and reduces cycle life.

Handling & Safety

  • Use protective gloves and controlled fixtures during assembly, as stored energy can cause sudden uncoiling if ends are released.
  • Inspect for edge nicks, surface damage, or set formation during servicing, as these defects can initiate fatigue failure.
  • Keep the spring free from abrasive dust and corrosive exposure; use suitable protection if the application environment is harsh.

FAQs about Flat Spiral Springs in India

Q1 What is a flat spiral spring used for?
A flat spiral spring stores energy in a coiled strip and releases it as controlled torque. It is commonly used in rewind mechanisms, reels, timers, clocks, retractors, and compact return systems.
Q2 How do I select the right torque and size?
Selection depends on required torque, working angle, available OD/ID space, and end anchoring style. Sharing your housing dimensions and operating travel helps match strip width, thickness, and turns accurately.
Q3 Do you supply spiral springs for reels and retractors?
Yes. We supply rewind and reel spiral springs for tool reels, cord retractors, safety covers, and similar assemblies requiring stable return force and consistent winding behavior.
Q4 What end forms are available for flat spiral springs?
Common end forms include inner hooks, outer hooks, loops, tabs, and slot types. The correct end formation depends on your drum or housing design and prevents slip during operation.
Q5 What information should I share for a correct supply match?
Share OD/ID limits, working angle, desired torque or pull force, coil direction, end form details, and application duty cycle. A drawing or sample helps ensure repeatable fit and performance.
