Rack and pinion for sliding gate: Module M4/M6, material & assembly
The right rack and pinion determines smooth operation, durability, and safety. Here you will find a compact practical guide – with verified links to suitable products from Tormeister 24.
Introduction
Jerking when starting, rattling noises, or visible tooth wear? Often the problem isn't the motor, but the rack : incorrect module, unsuitable material, or improper installation without clearance. In this article, you'll learn how to correctly determine module M4/M6 , weigh the pros and cons of steel versus plastic with a steel core , and install the rack so that your sliding gate operates quietly and reliably.

✅ Advantages & Benefits
Plastic racks with a steel core dampen vibrations and transmit less motor noise to the gate.
Steel rack and pinion systems are extremely robust – the right choice for heavy or frequently used sliding gates.
If the module and backlash are correct, the teeth mesh cleanly – this protects the drive, pinion and gate mechanism.
⚙️ Technical background: Module & material
| variant | Typical application | Advantages | link |
|---|---|---|---|
| Module 4 – Steel (1 m) | Private & commercial gates with medium loads | Very robust, screwable | Steel rack M4 – 1 m |
| Module 6 – Steel (2 m) | Heavy/industrial sliding gates | Maximum rigidity, boltable/weldable | Steel rack M6 – 2 m |
| Module 4 – Plastic (1 m, steel core) | Living environment with a focus on noise reduction | Quiet operation, including mounting hardware | Plastic rack M4 – 1 m |
Important: The module (M4 or M6) is determined by the drive. If modules are mixed, the teeth will not mesh correctly – excessive wear is inevitable.
🧭 Selection in 60 seconds
- Check module: Datasheet/type plate of your drive (M4/M6).
- Material selection: Residential area → plastic/steel core; high load/cycles → steel.
- Mounting type: Screwing (adjustable) or welding (maximum stiffness with steel).
- Plan for safety: light barrier and, if necessary, safety contact strip 8.2 kΩ .
🔧 Assembly: screwed vs. welded
- Easily adjustable (height & play).
- Especially suitable for plastic rack and pinion gears with a steel core.
- For heavy loads and everyday industrial use.
- Place the tack points at an angle, then align them in a straight line – avoid distortion.
- Align the pinion and rack to the same height; leave slight backlash between the teeth.
- Mount sections "butt joint", avoiding offset.
- Install and test safety devices: light barrier / contact strip .

Steel rack M6, screwable/weldable – maximum rigidity. See product details .
🧰 Maintenance & Care
- After 2-4 weeks, perform an assembly check: tighten screws, check for play.
- Grease steel sparingly (corrosion protection & smooth operation); plastic/steel core usually dry – observe manufacturer's instructions.
- Test the safety function (light barrier/contact strip) monthly.

❓ FAQ
Is the M4 "quieter" than the M6?
The sound depends more on the material and correct adjustment. Plastic racks with a steel core audibly dampen vibrations.
When do I need an M6?
If the gate load or usage is very high (commercial/industrial), M6 offers more reserves and high stiffness.
Screwing or welding?
Privately, these are usually bolted together (adjustable). For steel and extreme loads, welding may be advisable – always ensure they are perfectly aligned.
What safety measures are mandatory?
At least one light barrier in the passageway; depending on the standard/application, an additional safety contact strip at the closing edge.
