ROOF SLIDING ROLLER – KRONE 550018967

Precision component for the sliding roof system

The sliding roller for the roof with part number 550018967 is an essential element in the rolling mechanism of sliding roof systems for KRONE semi-trailers. Although visually similar to other parts, its specific size of 24 mm x 11.5 mm makes it critical for certain roof carriage configurations, ensuring smooth rolling and preventing jamming in the guide rails.

This original (OEM) part guarantees the tolerances required for the fluid movement of the top tarp, preventing premature wear of the aluminum rail profile.

Technical specifications:

Key benefits:

• Dimensional Precision: The 11.5 mm width is critical for correct alignment in the specific rails, eliminating lateral play that can cause noise during operation.

• Robust Construction: Manufactured from high-quality metal, the roller withstands the dynamic loads exerted on the roof during opening and closing.

• Reliability: As an original KRONE part, it ensures an extended service life, minimizing downtime in the workshop for roof mechanism maintenance.

• Fluidity: Reduces the effort required by the driver to maneuver the roof, facilitating loading/unloading operations.

Signs of wear (When to plan for replacement):

• Abnormal noises: Squeaking or metallic knocking sounds while sliding the roof.

• Difficulty in maneuvering: If the roof requires extra force or stops abruptly during travel.

• Deformations: Any signs of flattening on the rolling surface or noticeable play of the roller on its axle.

• Rail damage: Traces of uneven wear on the guide rail, which indicate that the roller is no longer rolling correctly.

Maintenance recommendations:

1. Periodic inspection: Inspect the rollers during seasonal tarp maintenance.

2. Cleaning the rails: Keep the tracks free of impurities; sand grains or metal debris can quickly damage the roller surface.

3. Set replacement: If you have identified a worn roller, it is advisable to check the other rollers on the same carriage, as wear tends to propagate evenly throughout the sliding assembly.

Do you need assistance in identifying other roof carriage components (such as axles or fixing systems) to complete the maintenance of your semi-trailer?
