UPRIGHT (POST) ROLLER – TECHNICAL SPECIFICATIONS

Guide roller Ø24 x 97 x 21.5 mm – SCHWARZMÜLLER Compatibility

This high-performance roller is an essential component in the sliding mechanism of vertical uprights (posts) for curtain-sider semi-trailers. Designed to handle dynamic loads during loading and unloading operations, the roller ensures smooth and quiet movement within the guide rails.

Compatibility with top manufacturers such as Schwarzmüller (Part Number: 284 014) confirms the high manufacturing standards of this item, serving as a core component for maintaining the structural integrity of bodywork systems.

Main technical specifications:

Technical advantages:

• Stability in motion: The precise geometry (Ø24 mm) prevents "play" of the upright in the rail, eliminating vibrations and premature wear of the metal guide.

• Premium material: The reinforced polyamide offers a low friction coefficient and excellent resistance to intense mechanical stress, weather, and corrosive agents (road salt).

• Durability: Designed for thousands of sliding cycles, the roller resists structural degradation caused by the demanding work environment of road transport.

• Easy installation: The 97 mm axle structure allows for quick and secure fixing into the original upright configuration, without requiring structural adjustments.

Wear indicators – When should the roller be replaced?

• Sliding resistance: If the upright becomes difficult to move or requires extra force when opening/closing the curtain.

• Noise: The appearance of metallic sounds or an uneven "hissing" during the sliding of the upright (a sign that the roller has become oval or cracked).

• Visible play: If the upright leans excessively or "wobbles" in the rail when manipulated manually.

• Visual degradation: Cracks, missing chips from the polymer material, or signs of uneven wear on the circumference of the roller.

Maintenance recommendations:

1. Cleaning: Keep the guide rails clean; accumulation of dust or rubber debris can accelerate roller wear.

2. Inspection: Check the integrity of the rollers at each semi-trailer technical inspection.

3. Preventive replacement: If you notice a roller with signs of fatigue, it is recommended to replace the entire set on that specific upright to ensure uniform load distribution.
