Spare parts for sectional doors – the complete overview

Spare parts for sectional doors are the foundation for safe, long-lasting, and convenient door operation. A sectional door consists of many moving parts that are in daily use and subject to wear. These include spring systems, wire cables, rollers, hinges, brackets, shafts, safety technology, and seals. Only when all components function properly does the door remain reliable, energy-efficient, and safe. In this comprehensive guide, you'll learn everything about technology, areas of application, standards, installation, and purchasing advice—and why you can get tested spare parts from Tormeister24 .

Why spare parts for sectional doors are so important

Sectional doors are highly stressed structures. Every time they open and close, enormous forces act on springs, cables, rollers, and hinges. Even minor defects can impair functionality or compromise safety. Regular maintenance and timely replacement of spare parts are therefore essential – both in residential and industrial applications.

Spring systems – torsion springs & tension springs

Springs are the heart of every sectional door. They balance the weight of the door leaf and ensure smooth operation.

• Torsion springs: mounted on a shaft above the gate, for large and heavy gates.
• Tension springs: installed on the side of the gate, more compact and easier to install.

Typical damage includes spring breakage or material fatigue. Replacement should only be performed with special tools (e.g., clamps) and is particularly safety-relevant for torsion springs.

Wire ropes & slack rope switches

Wire cables connect the springs to the door leaf and transmit the force. They must be precisely tensioned and run synchronously. Damage could cause the door to fall uncontrollably.

Slack rope switches are safety components that detect when a rope sags or breaks. They immediately stop the drive, thus preventing accidents.

Casters, roller holders & hinges

Ball-bearing rollers are crucial for a sectional door to run quietly and smoothly. They are mounted in roller holders , which in turn connect the panels to the hinge elements . Worn rollers cause loud noises, jerky operation, and increased wear on the rails.

Consoles – Floor & storage consoles

• Floor brackets: secure ropes and tension springs in the lower gate area.
• Bearing brackets: hold the torsion shaft to the side walls.

Both components are essential for stability and must be corrosion-resistant and firmly anchored.

Shafts & shaft couplings

The torsion shaft transmits the torque of the springs to the door. Large industrial doors use multiple shafts connected by shaft couplings . Only with a precise coupling can the door run synchronously and safely.

Safety technology for sectional doors

• Optosensors: integrated sensor strips in the closing edge that detect obstacles.
• Light barriers & light grids: Personal protection through invisible protective fields.
• Wicket door contacts: block the door movement as long as an integrated door is open.

All safety systems must comply with EN 13241 and be tested regularly.

Seals & Accessories

Gap seals and door seals prevent drafts, dust, and energy loss. Touch-up pens allow for cosmetic repairs of small scratches and rust spots. Seals are becoming increasingly important, especially in the area of ​​energy efficiency.

Care & maintenance of spare parts

• Visual inspection: at least every six months for cracks, breaks or wear.
• Lubrication: Regularly lubricate rollers, hinges and springs with a suitable lubricant.
• Replacement intervals: Replace wire ropes and springs every 5–10 years.
• DGUV test: required for industrial use.

Buying advice – which spare part fits?

To select the right spare part, the following points should be considered:

• Nameplate: Check manufacturer and model information.
• Dimensions: Determine spring diameter, rope length, and pulley size precisely.
• Area of ​​application: private or industrial.
• Assembly: many spare parts can be replaced DIY, but springs and shafts require a professional fitter.
