Boat Trailer Side Roller 70 x 90 mm – 17 mm Bore, Wide Support for Stability
The 70 x 90 mm side roller stands out with its greater width (90 mm), which provides an increased contact area against the boat’s side. This results in improved stability and weight distribution, especially for medium-sized boats (around 4–5 meters in length). The 70 mm diameter makes it suitable for standard brackets, while being large enough to absorb minor bumps without harming the hull. The roller has a 17 mm bore to fit common trailer shaft bolts.
This model is available in white and black versions. The white polyurethane roller offers the advantage of no-mark contact – as it rubs against the hull it won’t leave streaks, and it is slightly firmer, which helps it roll under pressure. The black rubber roller, on the other hand, provides classic flexibility and cushioning, which is valuable when driving over road bumps or when the boat is loaded less gently. Both types are durable in the face of weather exposure and prolonged use in wet conditions.
The wide profile (90 mm) of this roller makes it extremely useful for keeping the boat upright. As the boat is winched onto the trailer, the roller covers a larger section of the hull, reducing the chance of tilting or wobbling. This makes centering easier – the boat naturally finds the correct position between the rollers. The 70x90 mm roller can be installed in combination with smaller or larger rollers on the same trailer to achieve an optimal balance of support along the entire hull.
Use Cases and Recommendations:
- Recommended for boats about 4–5 meters long, where a wider roller adds stability during loading
- White roller: ideal if you want to keep the hull clean – it won’t leave black marks; black roller: preferred for regular heavy use and when a few marks are not an issue
- Place this roller at key points along each side of the trailer – for example, mid-hull – to help balance the boat during loading. Combine with other side rollers to ensure full support
- To maintain optimal performance, rinse off sand or salt from the rollers and check their condition periodically. Replace the roller if you notice significant wear or deformation to ensure your boat’s safety
