The 91112 Blue Smooth Wobble Roller is designed for boat trailer multi-roller and wobble-roller systems. Measuring approximately 100–106mm diameter × 87–88mm wide with a 20mm bore, its smooth polyurethane surface provides low-friction hull support during launching and retrieval. The blue roller offers durable, UV-resistant performance and is particularly suitable for aluminium/alloy hulls while also being listed by suppliers for fibreglass applications.

Signs the Wobble Roller Needs Replacing

Rollers that no longer rotate freely should also be inspected along with their shafts and retaining hardware.
