GL-15154 26MM roller

A 26mm Sliding Roof Roller is a high-precision nylon wheel specifically designed for the sliding roof systems (often called "Edscha" or "Schiebeverdeck" systems) of heavy-duty trailers and commercial vans.

Unlike side curtain rollers which bear vertical weight, these roof rollers are usually mounted on the roof arches (bows) to allow the entire roof tarpaulin to collapse forward or backward for top-loading.

Key Technical Specifications

• Wheel Diameter: $26mm$ (Standard for several European rail systems).

• Wheel Width: Typically $17mm$ to $19mm$.

• Material: High-grade Nylon (Polyamide) or POM. This material is chosen for its "self-lubricating" properties and high resistance to flat-spotting under the tension of the roof tarp.

• Bearing: Usually contains a sealed ball bearing to prevent dust, grit, and moisture from seizing the roller.

• OEM Compatibility: This size is most commonly associated with Schmitz Cargobull, Edscha TS, Sesam, and Kogel sliding roof systems.

Common Applications

1. Roof Arches: These rollers sit inside the top aluminum rail, allowing the cross-bars (arches) to slide effortlessly when the roof is opened.

2. Schmitz Trailers: In the Schmitz system, these are often referred to as "Roof Arch Rollers" (Part No. 120260001 or 1016741).

3. TIR/Customs Sealed Transport: They are essential for systems where the roof must be completely secured but easily retractable for inspections or overhead crane loading.

Why 26mm Matters

Using a 26mm roller in a track designed for 24mm or 30mm will cause significant issues:

• Too Small: The roller will "wobble" or tilt inside the rail, leading to the roof arches jamming or the nylon wearing unevenly.

• Too Large: The roller simply won't fit into the "C-channel" or "Ω-channel" of the aluminum roof rail.

Maintenance Tip

If you are replacing these, check the axle bolts. Over time, the vibration from travel can loosen the bolts that hold these $26mm$ wheels to the steel roof arches. If a roller is seized, it’s better to replace it than to lubricate it; grease inside a roof track often does more harm than good by trapping dirt and creating a grinding paste.
