Torsion spring for sectional garage door: correctly identify and safely replace
Misalignment, noise, sluggish drive – often the spring is the cause. Here you'll find clear selection guidance, a measurement checklist, and sensible set combinations to ensure your gate runs quietly, smoothly, and safely again.
What this is about
Torsion springs balance the gate leaf. If the spring specifications or settings are incorrect, everything suffers: operation, drive, and safety. This guide explains concisely how to determine the correct spring (wire diameter, ID, length, direction of rotation), which parts belong together (bearing bracket, coupling, cables, tools), and how to properly commission the system . Includes verified links to the appropriate parts.

Advantages & Benefits
The correct spring relieves stress on the drive and audibly reduces vibrations.
Smooth opening/closing, less wear and tear on rollers, hinges, and ropes.
Correct spring + intact sensors = reliable stopping and predictable servicing.
Technical background
Wire diameter , inner diameter (ID) , effective length , running direction (LHW/RHW). Also: shaft size (usually 1″/25.4 mm) and cone type.
Fixed and clamping cones on the 1" shaft transmit torque. Couplings connect shaft sections without backlash.
Incorrect spring → drive struggles, gate rocks, sensors malfunction. Correct spring → smooth operation, longer lifespan.
Selection & Measurement Aid
- Measure wire diameter with calipers (e.g. 6.0 / 6.5 / 7.0 mm).
- Note the inner diameter (ID) of the spring (e.g. 51 / 67 / 95 mm).
- Determine the effective length (unstretched).
- Direction of rotation: LHW = left-hand winding, RHW = right-hand winding.
- Spring + bearing bracket (if bearing runs rough).
- Spring + shaft coupling (during shaft conversion).
- Spring + wire ropes (in case of tilt/rope wear).
- Plus clamping tool – safety first.

Application & Assembly
- Torsion springs are under high tension. Professional installation is recommended.
- Use only suitable clamping tools – no makeshift tools.
- After work: test end positions, force cut-off, and sensors.
- Take photos of the spring, cones, nameplate & bearing bracket.
- Note wire diameter, ID, length, LHW/RHW – then order.
- If the structure is tilted: check/replace the wire ropes.
No detailed instructions here – if you're not experienced, leave the featherwork to a professional. We can put you in touch with one if you wish.
Practice & Acknowledgements
Thank you for your measurements and detailed photos. This allows us to match the correct spring in minutes – without any back-and-forth.
Maintenance & Care
- Annual visual inspection: spring, cones, bearings, cables.
- Remove dirt, avoid excessive grease in the rail.
- Regularly test the sensors (light barrier/closing edge).
Why we are the right ones
We consider the entire system: spring + bearing bracket + coupling + cables + tools. Result: quieter, safer, longer-lasting operation – without guesswork.
FAQ
What data do I need to find the right torsion spring?
Wire diameter, inner diameter (ID), effective length and direction of travel (LHW/RHW). Photos are helpful.
How can I tell if a spring is overloaded or the wrong type?
If the gate stops, jerks, falls too quickly, or the drive struggles, then check it.
Do I need to replace both springs?
Recommended. This ensures that the barrel remains symmetrical and the service life consistent.
Can I reuse the old wire ropes?
Only replace if it's in top condition. If it's crooked or worn: replace it immediately.
Which wave do I have?
Usually 1″ (25.4 mm) for garage doors. A photo of the shaft/cones helps with matching.
DIY or professional service?
Working with feathers is tricky. If you're not experienced, leave it to the professionals – we'll advise you quickly.
Are there any suitable assembly videos?
Yes, in our magazine you will find clear videos for common tasks.
What's the quickest way to place the correct order?
Upload the measurement sheet, enter the dimensions, attach 3-4 photos – we will get back to you with a set recommendation.
Quieter operation instead of spring problems
We'll put together the perfect combination for you – spring, bearing bracket, clutch, cables & tools. Order once, and you're all set.
